Before commenting: It isn't the temperature of the water. I didn't kill the yeast. It isn't the yeast, I used packaged and bulk. It isn't the sugar, I used white and brown. It isn't the tape, I made taped and untaped traps. None of them worked. None of them worked because the trap design doesn't work. It is not designed to catch adult mosquitoes. So if you have a new suggestion as to how to get the trap to work, please comment. Otherwise, hundreds of people have already made comments telling me what I did wrong. They're all wrong, and I have proof. No one has provided proof it works. Watch this video for more on this controversy: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jFlmzntJHk0.html
Douglas Conlin so, if this clearly failed, what can we make that will actually work? I camp. a lot. and I wouldn't mind being able to make a trap I can toss in my pack to kinda somewhat control those mosquitoes.
to be clear, I'm in no shape form or fashion here to dispute anything you found. clearly this failed, and the why isn't really that important. I legitimately want a design that works lol.
I set out to show if the trap worked or not. You're right, doesn't matter why if we now know the answer is no, it doesn't work. Making a trap that does work is a great idea, but I'm not the guy to do it, since mosquitoes bug other people much more than me.
Douglas Conlin i have used this type of trap for flies. I use water and a little bit of manure. The tape stops them from getting out the sides and the trap fills up in a couple days. I never tried the mosquito ones with carbon dioxide through yeast and sugar water though
This is the first time I have watched your videos you made over 6 years ago. OMG … you made me laugh and rewatch them. I even signed up to RU-vid to rewatch them. If you ever need a partner in crime to complete any future experiments let me know . What a lovely presence you have and hell funny with several cups of dryness thrown in. PS I successfully pulled my citronella coils apart. First time ever! Thank you and happy days 🦟🦟🦟🦟🧪🧪🧪🧪😎😎😎😎
Your trap didn't work because I wasn't in it. Mosquitoes go where ever I go. Here in Alaska they are considered the state bird, you can shoot them and make a fur coat.
alaskanalain, come get your relatives!! :-))) In Alaska, they may have made themselves at home and go where you go, but here n Florida is where they come on vacation to visit me!!!
Here in Georgia they will eat you up!!! I have used various mosquito sprays and tea tree oil. Right now I have about 7 or 8 mosquito bites that I have put clear finger nail polish on to help with the itching.
Yeah I've tried this type of trap as well and had no luck. But I did figure out that setting up a mosquito death pool works wonderful. Last year I set up a kiddie pool and every time I found mosquito egg rafts floating around I would burn them with a propane torch. Any larvae that had already hatched I used mosquito dunk tablets so they wouldn't survive. I must have eliminated 20,000 mosquitos and have already noticed a big difference this year.
Who told type 0 blood gets the first bites is full of shit! I am A+ and the mosquito bastards eat the living shit out of me. My wife is 0 + and the little blood suckers don't bother her at all. I started to take B1 vitamins and now I am bothered less than usual. There has to be a better way to get rid of them. .
For the people claiming you have to use a specific kind of sugar, you don't understand how fermentation works. Anything from fruit juice, fruit like bananas, refined white sugar, honey, brown sugar, syrup, and so on, all work, as long as there isn't something like salt in it. Look up how to make moonshine or bread and you will see that the source of the sugar, only effects the taste, not the ability to ferment, which creates carbon dioxide. Using Brewers/Wine Yeast you can ferment to higher alcohol content, but any sugar will ferment with the presence of yeast, water and within the living temperture. You can start with warm water or use room temp water. One thing that is important, is to test that the yeast is still alive. It is very possible that many people are using very old yeast that is no longer able to do it's job effectively, but if it bubbles within 72 hours, then it's alive. I probably used really really old old yeast, but I bought some fresh yeast to play around with fermenting (then discard). I feel like what the "DIY" should include, is how to proof your bread yeast. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ksziuzwLuGY.html
I found out quite by accident how to trap mosquitos and those pesky houseflies. I was washing my deck furnature one day and had a large light beige Tupperware bowl full of sudsy water for my wash rag. After I was done I put the bowl up on the railing in the shaded area of my deck to dump out later. All of a sudden my company came early and I forgot all about it. The next day I dumped it out and to my surprise there must have been at least a hundred flies and a few hundred mosquitos in the water. Now I do it all the time if I know I am going to be spending time outside or on the deck with friends.
Thanks for the tip Jerry! I will try a large bowl of sudsy water placed in the shade. I'll also get back with you with the results, could help a lot of people looking for a way to control mosquitoes.
One way to lessen the amount of bites is knowing what attracts skeeters in the first place. Basically, it depends on how you smell and since mosquitoes have excellent scent receptors in their antennae, they can smell any human within 100 feet easily. Unfortunately, it also comes down to genetics and 85% of the reason why mosquitoes prefer some people over others is due to their genetic makeup. Here are some of the main factors that make someone a mosquito bite magnet: 1) Exercise and Lactic Acid Production- The sweatier and smellier a person in the more attractive they are to a mosquito. Individuals who produce more lactic acid, which is emitted from our bodies via sweat glands, will draw in more of the pests to their general vicinity. Also, the more perspiration and the older it is, the greater the buildup of lactic acid, meaning your a tasty meal. Research has proven that fresh sweat isn’t as attractive to a mosquito as day old sweat appears to be, so taking a shower after working hard or exercising can make a huge difference on how many bites you’ll end up getting. 2) Bacteria- Our skin is literally crawling with bacteria and it’s estimated that the average human has about one trillion or so bacteria on their body. The types of bacteria living on our skin can vary greatly from person to person and some varieties affect how much an individual gets bit by mosquitoes. For example, it has been found that if someone has Staphylococcus and Variovorax present on their skin, they’ll likely suffer more mosquito problems. The opposite is also true, other types of bacteria act to make our skin less attractive to mosquitoes. A few of those types of bacteria include Pseudomonas, Delftia, and Actinobacteria. You definitely want those crawling on your body! 3) Blood Type- The type of blood you have coursing through your veins factors greatly into the risk of whether or not you’ll end up suffering from more bites than others. Studies have found that people with Type O blood are bitten most often, followed by Type B, then Type A. In fact, Type O’s are so appealing to mosquitoes that they’re twice as likely to suffer bites than Type A. In addition, if you happen to be among the estimated 85% of people who emit a certain chemical that gives away your blood type through your skin then mosquitoes will bite you long before they bite those who lack that chemical. It’s as if the pesky insects like to know exactly what type of blood they’ll be sucking, eek! 4) Carbon Dioxide- Even just breathing is enough to attract mosquitoes because they are drawn to the CO2 you exhale. Individuals who produce more CO2 get bit more frequently, thus pregnant women and heavy-set people who tend to breathe heavier need to take extra precautions to keep from getting bit. Another factor in relation to carbon monoxide is that beer drinkers have been found to get bit more frequently because they too breathe more heavily when under the influence of a few beers.

+Wesley Byrd LOL I wrote my above reply before reading your reply and while I didn't visit that particular website, if I recall, it is nice to know that some of the research that I have done has been confirmed by yours.
On this episode of Myth Busters.... I saw this somewhere and out of desperation I made it, yeah, same result. But had I saw this video, I wouldn't have wasted my time. Thanks for making it so others know not to waste their time.
Thanks for doing this and following it up. [I think we are all annoyed by bogus advice offered on the internet. Sure I'd like my brainstorm to be recognized and help the world, but only if it works.] There are commercial mosquito trapping devices that generate CO2 and use a meat smell, but last time I checked even these results are imperfect. What will work is a mosquito net with pyrethrum sprayed on it. Insects land on this and they die. Pyrethrum lasts several weeks. Safe to use on clothing as well. Treat window screens, porch screens. I've got a mosquito net that at night I curtain off the doorway to the bedroom. It's treated. Not too many mosquitos in Los Angeles. I do know that there are different levels of mosquito problems, even with the same species. In Detroit area, I could wear corn starch body powder to keep away mosquitos (My girlfriend and others are more likely to get bit than me even though I've got more BO, and presumably exhale more CO2). If I go into the woods, cornstarch is completely useless. So perhaps in India mosquitos will go in the traps: the 'are you hungry enough to eat a....?' principle. Bill Gates distributed mosquito nets with DDT in Africa. Same principal, but DDT lasts a lot longer (forever...) than pyrethroids (derived from Chrysanthemums) but caused problems when people used them for fishing nets. House flies. I've got store bought fly traps that use yeast and a common chemical. Smells like something is dead, thousands of flies--I've never seen a mosquito: not one. (Supports your experience) I've been using these traps for years against flies. One at the back of the house, one at the front. Effective. To lessen the stink I run some tape around the big entrance gap making the gap smaller about 1/2", less air flow in and out. For ants, those invasive Argentinian ants, I've found the Terra Ant Baits are pretty useless. It seems to just keep them busy. (You're the Terra company. Do you want to sell four traps a year or 40? Anything you do that noticeably changes the behavior of a pest will appear to be effective.) Instead I make my own, just using boric acid roach powder and a slurry of sugar at higher concentrations will first keep the ants busy like the Terra baits but, in a few days the numbers drop, after a week or so you can wipe out the colony. I've had 2-3 waves, new colonies replacing the old and then being wiped out. Now I'm not sure, my neighbors might be spraying--I haven't seen an Argentinian ant in almost a year. (Southern California). For my hummingbird feeders, I use a homemade water trap, but fill it with a 1:3 Dawn dish soap to water mixture. It dries out leaving a layer of soap. Ants won't cross it and you never again have to worry about the water level. Hope this helps. Insects are not the dominant Animalia branch on the planet because they're easy to suppress.
Here in Florida we have lots of mosquitoes! I have not tried this before. But as an experiment I'm going to try it this year. I have done a similar trap with cutting the soda bottle the same way. But the liquid I put in the bottom was apple cider vinegar and sugar water another time. The purpose was to trap some common house gnats. It worked for the house gnats very well. Got rid of em!
there is one mosquitoes trap that realy work, becouse it has inside what they like, I invented that trap,and it k1ll 80,000,000 I put hamsters inside a wood box,they live confortable there,and on the open top a insect electrocuter without the nonsense violet light(that atract only butterflyes) , and that trap acts to k1ll them when they try to get the hamsters blood,it kills thousands of mosquitos if put outside,K1LL ONLY MOSQUITOS. The smell and hot of the rats atract imediatly all mosquitos flying near that trap,thats what they looking for...
So I have made a similar trap that does work. There were dozens of dead ones in the water. I used a regular 5 gallon black bucket, clear doesn't work. Into that I put 3 packets of yeast, 60 ° water and 6 tablespoons of brown sugar plus a little dish soap. You then have to put the bucket into a cardboard box with the lid loosely closed so that the mosquitos can get in. The box provides shade which they like, but more importantly it allows the co2 to build up and slowly leak out of the partly open top. If you leave it in the open air without the box the wind will carry the co2 away too quickly to have any effect at all.
Ok but except the recipe calls for brown sugar not white sugar.. And you're also supposed to push the cut portion snugly into the bottom part of the bottle, not let it rest on top. If you follow the instructions properly I am sure you will find different results.
I live on a Tropical Nursery Farm with many different varieties of plants. The farm is located 120 km from North of Mumbai, India and comes under heavy Rainfall area. I have to irrigate my Plants after the monsoons are over and therefore my Farm is wet and Moist all the year around. I have some water tanks which I use to grow Water lilies where stagnant water is there. I have put the guppy fish. The Guppy (Poecilia reticulata), a freshwater fish popularly kept in aquariums, eats mosquito larvae and eggs. The Windows of my Home are always open and one will rarely find a mosquitoes in my Home. The lowest winter Temperatures never go below 10 degrees and on and average the Temperature remain 28 to 30 degrees centigrade. I do not spray pesticides and perhaps it has helped to keep other small reptiles and Frogs to survive and contribute to mosquito control. The Present time July - August month there is heavy rainfall and water is everywhere and there is a sudden increase in Mosquito Population and very difficult to control so was trying to see what else can be done
You didn't tape the bottles. Mosquito's instinct... Land on wall of bottle, then climb straight up. Without tape, you have gaps plenty large enough for a mosquito to just walk right out of. Your 'experiment' is pretty close to holding out a fly swatter, and then saying a fly swatter doesn't work, because no flys flew into it and killed themselves.
No gaps. The top and bottom fit. Also, no videos... no proof from any commentors that say the trap design works if you do it exactly the way they say to. I keep asking for pics or a video of trapped mosquitoes but no one has provided proof. It should be easy if you know what I did wrong and know how to make it work. Anyone got any proof?
Tried it in a heavily infested mosquito area. I was being bit by lots of mosquitoes while placing the trap. Several days later, not 1 mosquito in the trap. It does not work. However, if you don't believe me (and everyone else and the lack of people showing an amount of mosquitoes in theirs that is undeniably more than a random 1 or 2 that happened to be in there for whatever reason) go ahead and give it a try. It doesn't cost much to make and can be a fun little science project that you will dump out and throw a day or two later, (so that you don't raise maggots). I am 100% all for killing mosquitoes and I 100% wanted to believe this would work and even if I only caught maybe 10 mosquitoes, I would have been happy. Unfortunately, I should have cost at least 200, but instead, caught zero. I did nothing wrong with making a carbon dioxide generator and it being a trap, any modifications with ratios, temperatures, yeast placement, color and so on, would only change the effectiveness and won't turn a useless trap into a masterpiece. I think it is better to buy some Mosquito Dunks and give them a try. They are sold by a company that mass manufactures them SPECIFICALLY to kill mosquito larvae.
+Jay H Glad to hear I'm not the only one that made this trap in the expectation of results, (which as you say if there were lots of good results they would show them). Thanks for commenting, Jay H!
... / ... , man , perhaps your tap water is full of chlorine :that won't atract mosquitoes for sure. We are illiterate , still ,,, we've been using it even before the computers ever existed . Tomorrow l shall send you pictures of several bottles full of them , hanging from the orange trees . If l know how to use the computer system properly . So help me Lord !
+Manuel Luis I buy bottled water and distilled water and I know that chlorine can have an effect on yeast, so I doubt I used tap water, but I honestly can't remember. A fan with a screen over it, works great in a heavily mosquito populated area and all it requires is electricity and being in a dry/safe environment. The fan with a screen worked for me, I caught 3 or 4 mosquitos while I sat outside. Mosquito dunks seem to work, but it's hard to know for sure, because I don't have any proof. I took a black container and put water and green food coloring in it (to imitate algae) and a mosquito dunk. I add water when enough evaporates away, and i see some dead little flies in there, and nothing inside is alive and moving, ever. Even if the fermentation catches mosquitoes sometimes, it seems to have an overall low success rate among those who talk about it. In my searches, it seems to be tons of people talking about how to make one, some people talking about how they don't work, and the very rare person like you who claims they work. Maybe you are putting less sugar and less yeast in there, and because of that, the mosquitos see it as just standing water and they try to breed in there, and the alcohol kills them. Maybe we are all trying to make as much CO2 as possible, and as a result, making it unattractive to mosquitoes. You could probably just put mostly closed containers of water with rubbing alcohol added and kill mosquitos, given enough time and proper location.
The only thing you did correctly was cutting the bottle. This has and still does work in my front yard. 1. Cut the 2 litre bottle in half 2. Pour hot water into the plastic container. 3. Dissolve brown sugar in HOT water. 4. Put about a tablespoon of yeast in the bottle. Do NOT mix. 5. Put the top of the 2 litre bottle into the bottom piece upside down and TAPE the edges shut. Use dark tape. If you don't tape it you lose too much carbon dioxide too fast.
Yeast has a hard time digesting table suigar because it is a disaccharide. If you use a monosaccharide the yeast can get going faster (something like apple or grape juice). The baking soda + acid reaction is great for getting a lot of CO2 at once, but it dissipates very quickly and also creates a smell that they don't like (bromine tablet like alkaseltzer works a bit better). It is also important to keep it warm, they need high temps to be active so keeping them in the sun is better than the cooler shade. Even when I home-brew my EC-1118 will start shutting down at below 70-65 F, and that stuff has been selectively breed to ferment at lower temps. I get swarmed by mosquitoes when I go outside and I have found that shoving my arms tnd face through some of my rosemary plants helps keep them off for at least 2 hours unless I am really sweating hard. If that happens I wrap up some rosemary and catnip in a bandana and tie it around my head and they want nothing to do with me.
hmm. You didnt seal the sides of the bottle with tape so the CO2 coming out is too dispersed. The only place the gas should come out is via the funnel. 2nd, its recommended to use brown sugar than white sugar, it responds better with the yeast to grow (it didnt look like the yeast grew at all in your video after the couple of days. if done correctly it should look like proper mould growing on the surface of the water - perhaps your yeast was dead? (You should be mixing lukewarm water with the yeast below 26 degrees C. 3rdly, you have to cover side of the bottle with black paper - mosquitoes are comfortable hanging around darker places. With an open bottle there too much reflection from sunlight during the day and the reflected light off the moon at night. Give it another go.
AirtechStudios I did, AirtechStudios. Thanks for your thoughtful comments. But I addressed them in this 22 minute video, -taping, brown sugar, checking the date on the yeast, (black paper was never mentioned in the instructions). The follow up video addressing all these issues is here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A7L85190lz8.html. The facebook Mosquito Trap is Busted Busted Busted.
Approximately what was the temperature in the area? Yeast does have a minimum that it won't grow under. Also the critters aren't as active in the cool.
I noticed the "build" was not was not quite the way the video showed. However, I did read your description you repeated the test and constructed new traps matched to the video description. I too, wondered about why they did not show the result? LOL! Thank you for your myth-busting video!
I have also made a number of these traps (with tape), and used every bait suggested... the traps DO NOT work. My property is in the Hawaiian rain forest, and my property is legendary in Kailua-Kona for the plague of mosquitos... The fan traps work OK, about the same as the $300 propane (CO2) traps. I've found if I take mosquito netting and tape it to a box fan (or other fan) and leave it running, I trap a decent number of mosquitos for the first few weeks, then the netting needs to be changed. Best solution; eliminate shade. Good for keeping mosquitos away, crappy for everything else.
Since the facebook Mosquito Trap doesn't work, (subscribe and I'll notify you when the extensive new testing video based on your kind comments and suggestions is ready), I invented a Mosquito Trap that actually does work. Here it is: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M-mATcgqiIA.html
Doug, understand the frustration, but is it possible that these devices work as a lethal Ovitrap? Encouraging mosquitoes to breed in them but trapping the next generation. supposedly Ovitraps have a 98% success rate if left with stagnant water and no chemicals for 6 weeks. This would be a long term measure to prevent infestation, so the method used does not effectively test the longer term effects of leaving these bottles stagnate
Mosquitoes hate things that reflect light. Mosquitoes are attracted to dark colors (like that black shirt you're wearing) you have to make your trap black. I have been making these traps for years they most certainly do work. It takes at least 24 hours to get a good carbon dioxide going with yeast water and sugar, he didn't wait long enough. There are better ways to make mosquito traps, but this does work. Like I said I've done it a hundred times.
My uncle use to simply use a uv light above a water bucket with a fan. The mosquitos head to the light and get dumped into the water. Works to keep the area clear while having a nice outing. That worked 40 years ago, maybe the mosquitos have gotten more sophisticated now.
Did you preheat the water? And add the correct amount of sugar he said 75 grams of sugar per 250ml of water .. And your water was not brown ..hmmm I'll try it exactly like he said.
The trap does work, the problem is in how you are testing it. It would be like testing a mousetrap in Siberia. We know mousetrap work but there are no mice in Siberia because it's too cold. So in theory testing a mice trap there would conclude they don't work.Mosquitoes are attracted to carbon dioxide in areas near water. So even though you are creating carbon dioxide, you need to be near water, not in the middle of the woods. Also you need to be within 100 feet of the area in which the Mosquitoes are located.
Different varieties of mosquito are actually attracted and repelled by different things. They don't all behave the same. I can tell you that this works very well in the San Antonio area. I caught dozens when I tried it. But the critters in the area like to knock it over and drink the liquid.
Mosquitoes are most annoying bugs around me, i have been in Malaria once in this season as well! :( I am really fed up of them. I have to spray daily inside my House, but outside house they do not let me stand even after sunset. Do you have any suggestion? Thanks
I have tried this trip here in Fiji and it does not work so I'm guessing its maybe the humidity that doesn't let the co2 get out of the bottle to attract mosquitoes I've tried this trap about three times and no luck
this mosquito trap works. you put on repel, off or cutter with the highest rating of deet. the mosquito moves in for the bite and the repellant springs into action, and the mosquito is repelled away after the human trap lures it in.
I am one of those victims of mosquitoes. I can be in the middle of nowhere and they find me. Many say I have that 'sweet' blood. Must be the case or something. Even with bug repel on I still get bit. Go figure.
Agreed...I didn't see him using brown sugar like the original post says. Also the temperature of the water is important...too hot and you'll kill the yeast. It looked like he was using bottled water, so maybe it was also too cool. The water needs to be warm. The post I saw actually had measurements for the sugar, water, and yeast.
Mosquitos are atracted to d co2 and its temperature like human body Ex. Sweat it has odor that creaytes co2 and atracts the mosquito plus the your warm body temperature This kind of trap not good at outdoor it must be use at indoor so that the temperature will long for a minute
what if you modify it a bit, like somehow put a cheap water proof light under it or better yet a blue light. I think theres cheap battery power lights. I wonder if that would make a difference?
Got this from 'How Stuff Works' "When a mosquito trap does not work, often the problem can be traced to either the choice of attractant or the placement of the unit. The trap must be placed upwind from the area where mosquitoes are breeding and living. And the chemical attractant must match the species of mosquitoes living in the area." I suspect that might be the truth of the matter as there are so many articles describing how these traps work.
These traps don't work though. In the years since I posted this video people have continually claimed they work if I would just make small adjustments. They claim they have made one that works. I ask for pics of their trap full of mosquitoes. No pics as the years go by. That means they're liars. Or maybe you can explain why they don't or won't give me proof.
@@DouglasConlin Yes I'm now convinced you are right. I made two using the instructions I found on RU-vid and after leaving out for over one week I didn't catch one mosquito but got bitten three times.
I tried this and did not catch any mosquitos, but did trap most of the house flies in the neighborhood. First year we did not have any flies in the house.
I don't know if this is something that other people have pointed out. But I am pretty sure that Mosquitos are not attracted to sugar or yeast. Maybe if you fill that bottle with blood, you will be far more successful?
I tried burning used coffee grounds in an almost used glass jar candle. That seemed to repel mosquitoes very well. Also, I threw some used coffee grounds on my burn pile. Kept them away for quite a while!
I've got a bug trap similar to this... I used it to kill the fruit flies in my home. Some apple cider vinegarA strawberryA drop of dish soap I did this with and without the strawberry. The 'without' container was a fail, but I'd already been using the other ones and had caught a lot of them... So maybe there just weren't many flies left to be caught. One thing I noticed on your video is - you didn't tape the top to the bottom. Bugs can climb the wall of the bottle and climb out of yours. I'd like you to retry the test, using tape to secure the top to the bottom. I used black electrical tape... But black duct tape should work too.
What the liquid is doesn't really matter,ive used ketchup,the key thing like you said is a piece of fruit,i think it's the fermenting fruit that attracts them.
Great video. I have tried every way doing this as well and they do not work. One reason you might not get bitten so much with mosquitos or not be bothered by it so much is immunity. In Central American and Mexico people do not have screens. Many houses do not have real windows. In the tropical areas there are billions of mosquitos. The natives just go on and they do not bother them. When they move to the US and have lived here for a few years and go back for a visit they find the mosquitos horrible. What happened? I think that lack of exposure to bites makes you immunologically less susceptible to the inflammatory reaction. In other words the bites are not what bothers people but the reaction with itching and swelling is. So if your body, because of a lot of exposure, is used to it that may be why you don't have much of a reaction to them. Also cigarettes and cigars are pretty good at driving them away. That is why Indians in the US used to live in long houses and smoke tobacco in the swamps of North and South Carolina. And one of the key ingredients in bug killers is nicotinoids. That was all we had years ago. Then we developed DDT and then neurotoxins and pyrethrins. Anyway thanks for the video.
Before testing, you have to ensure the trap & contents are prepared correctly, this was not prepared correctly, no wonder it didn't work! (Were there actually mosquitoes around?!)
I think you took them out when the Camera is not rolling, LOL... Joking :D. Thank you for the Video, now I don't have to try it :D. Although you need a Zapper and Octenol, it seems to makes more sense and definitely will work :D
Did you ever sleep in a room with a small hole in the screen? Think about how the mosquito found its way into the room AND BACK OUT of the room. They keep trying to fly in various locations until one allows them to escape. Yes, mosquitos are attracted to CO2, but when there's no blood around they take off. Trapped by a hole? Not if they can got out that screen. They just keep looking around until they find that huge hole that they flew in through.
You would be surprised,if you take a milk jug put dog poop in the bottom and fill the milk jug with about 9 inches full of water and put a hole in the upper side of the jug you will catch flies.When you hang it up,hang it up by the handle away from the house.Make sure the cap to the milk jug is on.Guaranteed it will work just make sure the hole you put in the side isn't to far up because flies like to fly upward and bounce around.but are attracted to the foul smell of the water so they choose to not leave the trap.You can see proof on You Tube that it works.
1. You need to use raw sugar and not refined white sugar. 2. You need to sprinkle the yeast on top of the COOLED syrup. 3. You need to thoroughly tape the top to the bottom of bottle using Duct Tape.
never tried this for mosquitos ... but we used these at job sites (without the yeast ... just leftover soda) to trap the flies and bees. Yes, the bees were a problem if you were trying to balance on some wall / beam and had something buzzing or stinging you. By the end of the week, they had a lot of bugs in them and the site was more or less bug free.
I myself do not have a big problem with the mosquitoes. I attribute this to the fact that I eat a lot of garlic. I wonder if Mr. Conlin eats a lot of garlic also.
You're giving pretty limited evidence to proclaim that these don't work! After five years, you probably should have done more investigation and learned that these traps do work. One issue that you did not consider is that mosquitoes are most active when it is not daylight. In fact, that is one of the most common aspects of mosquito activity. There are many other factors that you didn't consider, but this is enough to warrant a conclusion that your claim lacks support. If someone in a developing country these past five years had the materials but despaired of making a trap due to advice they saw from you, wouldn't it be terrible if because of you they never tried and, possibly, one of their children became infected by a disease? Another thing that scientists have found is that negativity sells better than enthusiasm. Your negative video has gone to the top of RU-vid's searches for mosquito trap and you have almost 1 million views. Any hypothesis on how many of those viewers were in a zone that had serious mosquito epidemic problems?
The basis of my conclusion is that those who insist the design works have failed to provide any evidence. A pic of mosquitoes in the trap would change my mind. Got one, Peter?
@@DouglasConlin It's not mine or anyone else's job to do your research for you before YOU make sweeping conclusions that impact the world. There appears to be evidence that this can work; this appears not to be any sort of hoax (why would someone cook this up?); and the successes would be much more visible if there were not a greater abundance of experiments that have failed, including yours. All this means is that the conditions need to be laid out more carefully. Baking one's first few cakes without recipes and without comprehending enough of the underlying science is sure to lead to failures. A lot of first-timers trying to bake a cake are going to fail. Does that mean cake-baking is false? If they were to publish that, wouldn't it look like "cake-baking is a hoax"? Does that make any sense? Thanks to American ingenuity and marketing, the streets of the developing world are now littered with cheap plastic bottles. It's also easy to find sodium bicarbonate and acids throughout the world -- and many other combinations such as sugar, starch, and yeast -- that can generate carbon dioxide and some heat. This is also one of the few solutions that require no electrical power. It's therefore no wonder that many of your visitors are from the third world, and it's also little wonder that these very materials might emerge as potentially life-saving ingredients. Jeering at efforts to make this work, snagging some high-tech product off of Amazon and seeing it delivered in a box to your door, may be an option for you and me, but not for most people in the world. Hence the interest here may go beyond first-world DIY fun, and your responsibilities and actions suddenly increase in value and scope. Going negative might score you a million viewers, but for your moment of fame you may be doing a disservice to hundreds of millions. Mr. Conlin, do you want to be a real hero? Do a bit more research and find out the key factors behind this simple, potentially life-saving DIY project and why so many more fail than succeed. Clearly, the principles make sense: mosquitoes are attracted to carbon dioxide from mammalian respiration, and apparently also body heat, among other things, and many species prefer dawn, dusk, and night activity. It appears one can lure mosquitoes into a trap from which they may either drown or have great difficulty escaping through flight. Problems with implementation appear to include arguably simple questions of ratios, mixture, temperature, aperture depth to the liquid, time, and placement options -- just like baking. Placing multiple experiments in a single location, as you and others do, might also influence results. I gleaned this from a mere half hour of casual cruising among the failures and successes. The evidence is right here before us if we look for it.
@@DouglasConlin Oh, I "have" lots of proof, and so do you. We all do: it is available in little corners all over the world -- on RU-vid, in people's minds and experience, and elsewhere. It's just buried under piles of hot trash like your so-called "experiment." Your response is an indication of a lack of will to do the minimum work necessary in science: clearly you have not done a thorough job of scrutinizing the prior art, because you have not found what evidence I and apparently others have seen online, and what stands to reason. Instead, you shunt your responsibility onto others. As I said before, since you're the one making sweeping claims, it's YOUR job of due diligence to demonstrate that there is no evidence out there, not mine. Otherwise, you're doing the developing world a massive disservice. Do you even know your own strength? You haven't done your due diligence. You're the one making dangerous sweeping claims, so how dare you deflect your responsibilities by continuing to lay it on someone else's shoulders?!
@@PeteZelchenko you are obviously an excellent typist. So many words! (Still no proof. .) I'll respond to your continuous comments in 2021, giving you a couple years to provide proof. Till then, I'm ignoring you.
I was about to try this out good thing I saw your video and saved myself a lot of hassle.. There is currently a dengue epidemic in the Philippines, so a lot of us are already desperate to rid of these mosquitoes
Instead of, "Not Biting ME," perhaps you are not allergic. I have known people that aren't allergic to mosquitoes. They don't get the red whelps. Anyways, good experiment. That one little science fact on density kinda shows how it won't work. Enjoyed that you used a few different set ups.
aggresivepassivist Thanks. I think perhaps mosquitoes are allergic to me. I've never gotten poison ivy either, so maybe I'm just crazy lucky. I'll do a video on poison ivy and demonstrate how I don't get it.
So they don't like me either. I was going to try this and you saved me time. So for now I'll just go out with my husband (because they love him) and they leave me alone.
nice, try experiment video of same trap concept but bigger container., the heat emitting fresh cutted grasses tampered in the container and covered with under trees rain wet soil dry leaves
Douglas, I'm living in a wooded area outside Athens, Greece. It's early September and the mosquitoes are everywhere. My neighbor has a sprinkler system that brings them to the estate because he likes to keep his lawn and plants watered. What is the most effective way to combat the mosquitoes? Is a bug zapper the best solution or is something better out there I could use?
there is one mosquitoes trap that realy work, becouse it has inside what they like, I invented that trap,and it k1ll 80,000,000 I put hamsters inside a wood box,they live confortable there,and on the open top a insect electrocuter without the nonsense violet light(that atract only butterflyes) , and that trap acts to k1ll them when they try to get the hamsters blood,it kills thousands of mosquitos if put outside,K1LL ONLY MOSQUITOS. The smell and hot of the rats atract imediatly all mosquitos flying near that trap,thats what they looking for...
I made this trap and still being bitten like shit by mosquitos. this trap does not work. i will stick to the conventional means of protecting myself against these blood suckers.
It does, Kathy. The yeast eats the sugar and gives off alcohol and carbon dioxide. That's the carbonation in beer. But in this case its a very small amount compared to a person breathing, so the trap doesn't draw mosquitoes like its supposed to.
I had a war with mosquitoes trying a bunch of things to repel and kill them. Until I finally just went and bought potent pesticides. Since then there are little to no mosquitoes
awzome doe That's practical for severe infestations, Problem with pesticides is that using it will escalate as time passes. So it has to be reserved for nasty cases.
Maybe it is a problem of yeast. In France, the (french) word for yeast corresponds to 2 kinds of "levures" : chimical one (and it will not work for mosquitos) or microorganisms, and these ones are of 2 kinds : bread yeast and beer yeast. I think you need beer yeast : beer yeast plus sugar in water will create a lot of CO2 which attracts mosquitos.
+roque ordonez I made the video in Delaware, a hot and muggy state with no shortage of Mosquitoes. Now I live in Michigan where I grew up. In Boy Scouts we would joke that the State Bird is the Mosquito.
mosquitos are able to stand on the surface tension of water, and that is how they lay their eggs in water, so "drowning" then as the trap tries won't work
I just looked at a bunch of these videos about DYI traps, and I'm not sure anyone else has noticed the following. Many people said their brown sugar & yeast trap didn't work. But one thing in every video I saw with the complaint that it didn't work was that they all placed their traps low, mostly on the ground. Mosquitos don't fly close to the ground--they fly at head or shoulder level mostly. Those I saw where people claimed some success with their trap were when their trap was at least at waist level. One woman even HANGS the trap at head level. Maybe that's one reason some say they catch them while others do not! You might try this with the trap hanging at head level, and see if it makes a difference. There also seems to be some difference of opinion about mixture density and darkness of the trap.
I think if someone had made a trap and had it catch lots of mosquitoes, we'd have some video evidence by now. The most telling evidence as to why the trap design doesn't work is that it can only produce a small amount of C02. I measured it using a balloon in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A7L85190lz8.html. The balloon held all the C02 generated by the sugar/water/yeast mixture. It was about as much as blowing into a deflated balloon once or twice, about a breath or two. That's not going to draw many mosquitoes because its such a tiny amount compared to a live human in the area breathing several times per minute. So its logical the trap design doesn't work.
I hadn't seen your other videos--well done. I wasn't arguing that it works, just wondering if elevation was a difference that makes a difference. ...But what's the main point of all this? --It is pretty well known that expensive "Mosquito Magnet" type traps that use CO2, heat, octenol lures, and a few other tricks, work pretty well. Lures are available, other design features are easy. The question is, how to build a trap DIY that costs less than several hundred $$, is fun to do, does not need frequent service and actually works--with available materials. Since it doesn't exist on youtube already, probably not. The key would be an easy, cheap way to produce CO2 and heat. A catalytic propane converter is probably the best bet, but I've never seen these available or how to get one. Have you?
propanemosquitotrap.com/. Also, I think the volume of CO2 emitted by a commercially manufactured trap would have to be much greater than the facebook mosquito trap design could ever emit. The purpose of the videos I made was to keep people from making a trap that doesn't work because someone wants to have something to post on facebook. I kept seeing that type of video all the time and knew it was probably bs because no one showed proof that it works. (It doesn't work.) (Thanks for your comments and I like your screenname.)
Douglas, take a look at this one--might have some basis behind it and worth a test. www.motherearthnews.com/diy/garden-yard/homemade-mosquito-trap-zm0z12jjzhun
I read the article and have a few comments: Mother Earth News is a great resource, but in this case the trap description is pretty complex. Add to that that the article is 5 years old and has no comments even though the article ends by stating, "If you try this homemade mosquito trap around your home, please report back on how it works by posting a comment on this page." There are no comments and even the author of the article didn't test the trap, only said it works in Africa.
I live in Thailand where mosquitoes are a big problem. Caught dengue fever 4 years ago almost died. A day doesn`t go by when I don`t get bitten no matter how hard I try to avoid them. even with our mosquito shields on windows and doors some still get in. Tried all the commercial traps, the one`s with ultra violet lights, different electric devices with chemical repellents, but to no avail. I really don`t think there are any reliable mosquito traps, either commercial or DIY.
+bugutwo That's a bummer. I get a lot of viewers from Indonesia and Thailand in search of some relief from mosquitoes. I wish this trap worked but it doesn't, so if I can't solve your mosquito problem at least I'm keeping some people from wasting their time building this trap. (Isn't it cool that we can talk to each other from opposite sides of the world? Amazing! Take care, bugutwo.
+Douglas Conlin Thanks for your reply. I am originally from Whitechapel in London (famous for Jack the Ripper), no relation, I hope. It is amazing this technology. Back in young days my folks never even had a telephone, and had to book a call abroad, process took 24 hours. Personal computers were still science fiction. Enjoyed your video.
Bad experiment, mosquitos are drawn to CO2 although outside it's immediately mixing with the air. I think this would work in a confined area like a bedroom where the CO2 isn't going to be blown away and diluted with fresh air.
... /... , it is not striking instantaneous : just put it there hanging from the trees and leave it. After 7 / 8 / 9 /... months you'll find millions inside the bottles . No need to warm - up water : ☀ Sun will be in charge , and as to produce carbon dioxide and sugar to attract mosquitoes and flies of all sorts , a putrid 🐭 mouse or putrid meat will do the trick to attract others ✈ flying insect in the area. We've been using it even before the computers existed.
You are so good looking and funny I love watching you ,you are very intertaining, I hope you make more video soon. Please. Love va your my favorite , bye for now. Take care !,
While all these comments, attempts to make anything to kill those .......,s, im willing to give anything a try, I am a 5 star prime beef blood bank. If there's a mosquito within 5 miles, it will find me! Repellent only makes me sick. Glad I found this site keep the experiments going, I will keep all you posted if I succeed.
It works, but you need to: (1) use a cube of brewer's yeast, don't use yeast powder the reaction is over too fast; (2) need to seal the edges of the trap with tape, (3) hang it in the air (very few mosquitoes are ground huggers.
Oh Richard! The instructions you give are (1) irrelevant to the design and function of the trap, (2) untested by you, (or if they are, you know they don't work), and (3) all said before in this comment section by people who comment before reading what others have said. I say make the trap your way, videotape your results, send me the tape of the trap working so I can eat crow. Sound good? Do it. Thank you.
Gee, I didn't realize that offering another point of view would irritate you. I guess you have set yourself the task of exposing whatever you set your sights on. Okay with me, because it is your show and income. Expose away, have fun, and may your revenue stream never fail. Bye.
Lots of comments on my video, but here's the final result: .ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A7L85190lz8.html Sorry to all you people who insist the trap works. It doesn't, and I took two weeks and made a 23 minute video to prove it. BUSTED. BUSTED. BUSTED. Please don't comment that it DOES work unless you have proof, (which you don't: because it doesn't work).
... /... , no, no, it works 100% fine. I could show some pictures of several bottles , plenty full of them , in several orange trees ,,, if l knew how to work fine with Internet . Is very effective . We use it for generations .
+Peter Griffin ... / ... , no, no , ... /... , l have proof in my boss'backyard it is effective. I shall take some pictures and send it to people to see in Internet . At first bottles were green . Now : completely black - full of them - plenty, by thousands. And very effective during 5 , 6 , 7 months , cold weather , hot weather ... ... The dead mosquitoes themselves producing carbon dioxide whilst on decomposition , calling for other mosquitoes to be traped .
+Douglas Conlin... / ... , tomorrow, l shall take pictures of the bottles hanging from the orange trees, and post in Internet : first they were green : now they turned black because they are full of all sorts of black mosquitoes .
Thank god I found this video. I thought I wasn’t making the trap right. I thought maybe the trap kills South Americans and Asian mosquitoes but not the ones we have here is the U.S.
Nope. I was only interested in whether or not the facebook design was fake or not because any video telling how to make it and how good it works had the comments disabled, (meaning the video makers were getting called out in the comments section for providing no proof it works. 4 years later, I still have no proof from anybody who insists it works.)
Great video. Best advice ever 'learn to tune them out, execute them when they bite...Be happy'. I am curious about your diet, If 'bugs' are not attracted to you, there is something in your diet that is an excellent repellent. That, or they just don't like you :) Well, I have to make one this things (live in South America). There is a new mosquito species this year and they are nothing nice. The idea of this type of trap is sound. There is more c02 escaping from around the outside of your trap than the hole in the center. Seal up those leaks with tape (not scotch, or boxing) but maybe electrical, or even teflon. I will try this, and post results. Thanks for the video, and great advice, and stay happy.
+Rod Cain Thanks for your comments, Rod! As for my diet, I eat whatever I want and get enough exercise and I feel healthy as a horse almost all the time. It could be something in my genetic makeup that keeps the mosquitoes from biting me, and I know it helps that I'm usually happy, borderline giddy, with life and all it offers, which probably makes me less attractive to mosquitoes. A happiness force-field? Poison Ivy doesn't affect me either. But sadly, I am allergic to political debates and can't watch them without feeling queasy. So I don't, -we all have our cross to bear.
i have a similar case. i live in a tropical country and mosquitoes are quite common here. sometimes when i hang out with friends, there are rare occasions mosquitoes would attack me but most often they simply arent interested in me at all. my friends would get bit but not one single mosquito lands on me.
