How I Treat Whiteflies In The Garden - What I Use, and How Often 

I had whiteflies last year like you had in this video. I will surely add pyrethrin to my arsenal this year. Thanks for sharing this video Jim. 👍🏻

Great tip! I had them late in the year. I think they were why I didn't have a fall crop of tomatoes. By the time I discovered them it was too late. They hide well.

Thank you so much for sharing your knowledge. Our family recently moved from Maryland to Forida. Boy there are a lot of different trials and tribulations here. Lots to learn. I was gifted a hibiscus for Mother's Day. Started to notice the leaves turning yellow, and dropping. Went to water and noticed flying white flys. Turned over the leaves and spotted white eggs on half of the plant. Been using soapy water w/ vinegar. Spraying over and under the last two days twice a day. Morning and evening. Tonight took rubbing alcohol and wipped the leaves. Removed dead leaves. Going to trim some branches. Next step is trying your method. Best wishes, and happy gardening.

Holly Molly your not joking on being invaded. WOW that was a mass of white flies. Cold Press Neem Oil is what I use. Not the store bought junk that is just about worthless. Good to see ya got them under control and for the tips. Stay safe and have a great day!

Great information Jim. I'm really glad I don't have whitefly challenges. Stay warm. Stay well. Best wishes Bob.

Same here in late summer Northwest Texas. I'd never seen so many little white flying vermin! We used the yellow sticky paper too with the plants we brought inside for winter.

Thanks for the video. I am starting to see them in my garden.

They’re monsters. Thanks for the video - very helpful. Cheers.

great advice, thanks for sharing

Great video, thanks!

I am in Texas and this my first year fighting white flies. I was treating pest with DE then they appeared then I tried Neem oil and Sevin.I pulled all my cucumbers as i was getting too annoyed. I think I will try your technique. Thanks for sharing.

I’m in Washington state and dealing with white flies on my 2 dwarf apple trees (first time growing apples). They seemed to magically show up while I was gone for a week in July, but since I’ve sprayed them with a Neem oil mixture and hand squashed the little flies daily to control the population…so far so good. I’ll definitely be in the lookout next year for this! Thank you for making this video. :)

Great Channel.

Thank you this really helped

Hi Jim, i'm still learning but I think I can share a thing or two after battling white flies the 3rd year now. My first year started like your video but it turned into a disaster by the end of Sept because I had no idea what those are. They're so nasty, they multiplies fast, they carries disease and spread them everywhere. We're in northern CA, winter is warm enough for my tomatoes, pepper, and whiteflies to survive. During late summer, our city is usually so badly infested, you'll see whiteflies literally everywhere. I realized in such place there's no way I can make them extinct, but I've found a few ways to keep my plants going and not driving myself crazy. 1. mulch. I mulch every plant rigorously 2. soil. I changed all my container soil to foxfarm Ocean Forest, I gave up using those cheap ones or mixing manures with cheap potting mix, adding a bunch of stuff in there. (I think the money is well worth it, at least we have cherry tomatoes and jalapeno to eat all the way till Dec). That'll also save me money on fertilizers, I don't need to use any water soluble ones, and I only use little bit of slow release organic fertilizer every few months, and I would always bury those under mulch. 3. Grow more flowers year round. Grow companion plants. They'll attract pollinators and good insects. I also grow garlic, green onions, herbs all over. 4. I have to spray regularly whenever I see signs of them coming back (usually finding clusters of eggs hiding underneath the leaves), I spray with neem oil, peppermint oil and castile soap, mixed in water. I have a series of sprayer, and when things are out of control I would get an backpack electric sprayer go twice a week for 2-4 weeks (thankfully last year I only need to use the big sprayer twice). Spray underneath the leaves. 5. About yellow stick pads, I would avoid them. It could be a way to monitor the pests in your garden, but I don't think it's going to help at all. I used to go crazy about them, and they would attract and kill both good and bad insects. In my garden, I was left with only whiteflies after a few weeks, since nothing can out number them.

Thanks for sharing. First season in a greenhouse and I have an infestation of whiteflies. I just sprayed Seven yesterday so we shall see what happens. Wish me luck

Supposedly Michigan zone 6A gets too cold for whiteflies to overwinter here, but we have them this year as bad as this video shows, if not worse. It has really been frustrating since our tomato plants in particular are mostly sickly and producing probably a 5th of what they would have if not for the major whitefy infestation. I will be following your advice as closely as possible as soon as I can purchase everything.

Exactly my approach. Pyrethrin really does work but not the safest in terms of beneficial insects. Neem oil is more for maintenance than getting rid of them.

Jim, thank you for the in depth video. Where do you buy your pyrethrin??

Just sprayed this morning with pyrithan. I’ve had them the last 3 years. I’ll pick up some neem oil and try that in a few days.

I have some three containers with yellow peppers in them that I've had for about nine or 10 months nursing them in and out of the sun in Florida when super hot I bring on a porch. I'm not sure if they're thrips or white flies but they're overwhelming the plants in a matter of week or two of neglect. I'm either going to follow your regimen or destroy the plans and hope they don't get into other things. I am in Orange citrus country in East Central Florida and I used to get white flies a lot in hibiscus and they would get into the citrus trees but I haven't seen that happen in 10 years maybe or in my garden plants either this is the first year in a long time. Thanks for your video clip

I had heaps of white fly on all my green vegetables plus other green plants I spray top and bottom leaves with wash up kitchen detergent 2 to 3 days apart unless raining that seems to kill a fair few they can not fly and get stuck to the leaves. Also use Seasol. Rick from Aussie

Fortunately I think I caught them early. Only one tomato plant (Black Krim) was infested, but it was a mess. I washed the undersides of the leaves ever other day for five days with a jet spray from my hose. I then hung lace wing eggs around the tomato plant. Watching to see if they return but so far so good.

Hello from Auckland New Zealand (currently summer) The white fly here are even in the neighbours bushes (coming over to my vege garden) and in the grass ! I’m using neem but will also try pyrethrum cause they just won’t budge. No plant is safe, not even the companion plants I have for pests

I mostly use neem oil for white flies. I will consider the pyrethrin but it does kill honey bees. Where I am in the summer (Seattle area), the sun sets really late and the honey bees are present in the garden very late. I would need to use the pyrethrin after dark or super early in the morning to be safe.

I have whiteflies indoors on my tomatoes. I knocked out the aphids with lady bugs. Smoke will send them flying into the grow lights. I use neem oil and insenticidle soap.

I use 2 teaspoons of dish detergent and 1 tbsp of lemongrass oil (peppermint oil is also popular) per gallon of water and spray down the plants. 2 applications seem to do the trick.

I WISH we only had that many white flies 😩 I don't live with my parents but I'm over here often to work on their garden... I went to the beach for a week and a half, and when I got back the ENTIRE GARDEN was absolutely INFESTED with white flies. I think I'm just going to burn it all down lol

SW Florida, with Whiteflies on peppers and ornamentals. Gave up on growing peppers. Still have these little killers🤨

Thanks im doing my forst hectare of habanero and im discovering they hatch like crazy in higher temperatures. Also found out one of the products i use is just mimicking nicotine (imidacloprid )and i could just grow and extract the tobaco

Thank you for the video. I don't have whiteflies, knock on wood. My scourge is Japanese Beetles. I just checked on Pyrethrin, it is organic and is to work on the beetles. I have been using Neem oil for the beetles and I need something organic for additional control.

And green lace wings from Arbico Organics does a number on them and aphids

I have a bad case of white flies. I have tried neem oil and a dawn detergent. Even doubled the amount of neem oil and still have those sob’s. I’m going to try to find pyrethrum and give that a shot!(nothing to lose at this point)..

I had them on my pepper plants last year.

I use a cup of Olive Oil and Water, .. in a empty spray bottle, shake good and let them have a good drink..

This year was horrible and sure did the plants in early. Wondering if 2nd year of drought and high heat mixed with periods of high humidity had anything to do with it.

Last year I had the worst infestation of white flies that I've ever seen! I used everything I had. Soapy water, neem and DE. I even invested in a hand held vacuum cleaner. I would suck up white flies until the battery died. I finally cut off all the leaves on the sweet potato vines, advice from my local nursery. I put the leaves in a garbage bag (inside sprayed with non stick cooking spray) to keep the flying ones in the bag. I also had to spray my other crops. It was a disaster, but I finally won the battle! I might even wait a year before growing sweet potatoes, just to be safe. I never want to have that problem again. Have a great Day!😆😄😄😄😄

Thanks for the tip on Pyrethrin,...My guava tree has been getting hit by those suckers periodically smh, c.press Neem oil & a fragrance free soap mix keeps them controlled but you can’t skip on treatment cycle or they’ll be back with a vengeance! 👍🏼

We are having a whitefly problem and I am noticing them mostly on my Eggplants.

Hello I used neem oil with pyrethrin in one gallon spray applicator but unfortunately killed my cucumber plants the neem oil seemed to have clogged the pores of the leaves and inhibited the plant to photosynthesize. I used 3 table spoons of neem and 4 table spoons of the pyrethrin. What’s a safe dosage of neem if you don’t mind to answer. Thanks

All you can do is check for them earlier this season and try to wipe them out before they get out of control. Problem is, it always happens right when there are a list of other garden chores that must be done so that you can't get around to it for awhile. I don't know how the pioneers survived the insect attacks, diseases, birds and other critters, drought and storms. Their lives depended on their success. At least we can run to the store.

Have them on my night-blooming jasmine every single year and the infestation gets really bad. I try Neem, nothing...they are back in a day every single time. Can't find anything that kills them or keeps them away at all, no matter how many applications. They destroy the plant. Never heard of Pyrethrin, but will give that a try.

I can't seem to get rid of the White fly. My plants was healthy and do great when I planted them. I started them all from seed myself. What can I do. This is three years now

I use malathon spray. Usually only one application is needed.

I found lots of this on my kale. Can I still my kale free many wash with water or not recomendable.?

What type of need oil and pyrethrin do you use? I don’t know what best?

They were horrible last year in central Illinois as well.

I like Whitefly I want them to came to my plants it makes them better. How can l get them

Oh my goodness. Last year my entire garden was infested. It was like a plague. I hope they don’t come back this year.

After ten years n still continuing, having no success with planting peppers due to insects, diseases n fertilizing errors. Trying not to use any poisonous chemicals, quite effective method to get rid of white fly is to spray high pressure fine mist water everyday for more than a week. It works.

We had whiteflies on our tomatoes three years running. Tried the organic sprays and fly paper sticky traps...it was a constant fight that i couldn't win. Last year after doing lots of research worm castings came up a few times and thought it was worth a try as gardening had become more of a nightmare than a pleasure. So when we put out our tomatoes in '22 we planted with worm castings then after some time and growing we dressed with more castings then once again after 2 or 3 more weeks. The whiteflies showed up about this time of year, late june , but didn't stay and had a wonderful whitefly free tomato patch!! We did about the same routine this year and again the flies appeared just a few days ago was out tonight and no signs of them when shaking the plants and found some of them on the underside of a leaf.. unresponsive , dead as a hammer!! I drug them off with my thumb and they fell to the ground! Never in my wildest dreams would i have thought something so simple and organic would work so well in fighting whiteflies and give our garden back to us.

The beep say to get rid of them is Irish soap mix it with water no dish soap you have to spray at night and early morning and put moth ball oround your plant Iit work for me I do natural things

White flies destroyed my garden. They were so bad the bug totally blanketed the bottom leaves of all my plants. I used Jacks neme oil and it did absolutely nothing. Have not started another garden because of these white flies.

I have white flies on my lettuce in my greenhouse. Is the stuff your using ok to put on lettuce? If not any ideas what to use

My goodness!! I have them inside! They drive me batty. I will have to get some pyrethrin.

i got hit with them during 2021 winter life in north Florida and never seen them and i have them worse then you never used pyrethrin will try and used neem oil before thanks

Try Encarsia formosa, if it available in your country.

Oooh what are those peppers call

G'day Jim, Thanks for this Video... I'd never seen these little White Flies before, but they pretty much wiped out my Zucchinis & Beans & Tomatos & Potatos this year. I found that they don't like Seasol Fertiliser (suitably diluted) poured on the Leaves, but they leave the Folaige with a white Fungus/Mould, and I found that amputating all the effected Leaves was the only way to stop the sickening Leaves from poisoning the rest of the Plant. Then I tried a 1.5% Solution of Hydrogen Peroxide sprayed on the Foliage, both sides..., and that seemed to hunt the Flies away and also kills the Fungus..., leaving the Leaves with dead brown patches on them where the Fungus has died. The Dwarf Beans actually appear to have recovered, growing new Leaves, Flowering, and producing a few late Summer Beans. I'll get a bigger Sprayer and try your Pyrethrum & Neem Oil. I sort of thought the White Flies seemed to appear after I applied chopped Sugar-Cane Mulch after my Seeds all came up. One of those "Pink & Red & White Silver-Beets/Swiss Chards" has flowered & gone to seed - but I dunno what if anything they'll grow...(?) ! My impression is that 55-Litre Tubs are too small in which to grow Vegetables, but the 90 to 110 Litre ones are fairly serviceable. Last week I posted a Garden Update featuring the major Carrot Harvest (6 in one day, to be given away to my mother, son & daughter - as against one at a time for my own consumption. 24 little Onions cost $36 to get set up to grow, and 2 dozen Carrots cost $55...; but the most expensive Produce has been 5 Cobs of Corn from 2 x 110 Litre Tubs of Soil, costing $110 - or $22 at per each (!). Hopefully, next year I'll have a better idea of what I'm trying to do...(?) ! Growing Food sure makes shopping in the Stupormarked into a humbling experience ; when regarding all the PERFECT Veggies which are being virtually given away almost for free (!). Such is Life, Have a good one... Stay safe. ;-p Ciao !

I am in the Philippines. I have a horrible time with them every year with egg masses like crazy. I use a bit of soap and oil in water with a sponge, wipe the undersides of the leaves as spraying is ineffective. I also use the yellow sticky traps for the bit of good they do for adults.

I got lots this year...

What is the name of the pyrithrin?

I saw this earlier when we went to Trick or treating I was having a panic attack

Is periproxyfan good to kill them??

Where do they come from?

we used Doctor zymes to kill white flies and used yellow sticky traps

White flies are on my rosemary plant. Ugh! 😮

I've been having a white scale-like hopping insect infest green bean, tomato, and occasionally pepper stems the last couple of years, especially in hot humid weather. I also found big infestations on young native black cherry and redbud. Until I saw your video, I thought they were whiteflies; then I thought they might be mealybugs; now I'm guessing flatid planthoppers. In any case they are annoying and seem to slow the growth of plants or worse, and I'm still trying to figure out the most effective way to control them.

Are these sprays harmful to bees?

I really hate how they flies fly around in the air and they sometimes get in your face and they are everywhere

What about if they are eating the grass? 🤔

If ya think whiteflies are bad outside, just get a couple of greenhouses going. AARRGGHH!!! Those things are relentless.

🧼 soap and peppermint oil

understand the life cycle of the whitefly and you almost have complete control. Spraying is good? but what is shown here is the whitefly being eliminated at the adult stage, it does nothing to destroy eggs or prevent hatching. So you will have the same problem. My solution is to spray every 4-5 days with a soap-based spray every 4-5days for 40 days within that period you will have stopped the life cycle. However, miss a spray session, then you will have to start the 40-day period again.

Good god my friend that's a bunch of flies

I had them for the past two summers. I hope they don't return this summer.

This brinjal leaves looks different

Ladybugs💯%fact

Good info but I think you did it to show off all your peppers again. Lol

little bastards destroyed all my plants

Why are you whispering? Why do you make me use google to know the chemical you’re using. I’m not talking about neem oil.

Got them in my grow tent. They are destroying my pepper and tomato seedlings
