I spent a lot of summer 2019 running from those dang things. We had a hive way up in a hollow spot in a tree not far from our door. They made it very difficult to leave or enter the house after dark. They were like moths, attracted to the smallest sliver of light coming through the shades over the window in the door. I made a trap with a five gallon bucket with about 6 inches of water, NOTHING but water in it with a light placed over the opening. I placed it away from the door so we didn't have to fight to get in and out. It killed about 40 to 50 hornets and rarely a moth or two and nothing else every night for almost two months. No more murder hornets around this year.
You put the piece where the holes for the bees to get out, IN the big compartment. So how do the bees get out? And: how about the results from this trap? How many hornets caught? How many bees still caught by a hornet while being in the trap?
I would have thought the bottom section of the plastic bottle that contains the tin with the bait would have needed a more secure way of holding it on otherwise in a strong wind I could see it coming adrift.
I just put Sugar water and chunks of wax for bait in bottom of clear jug,one inch hole towards top but on the face,set down OR hang it- CATCHES THOUSANDS...
Bald face hornets,wasp...etc.not Asian hornets but it would if we had them, but we don't at least their not established yet although I think I witnessed one two years ago
