That's a good idea if the vinegar stops working I might try it thanks. Sarah

Great idea. You can use almost any sweet juice with a few drops of dish detergent like Dawn. VAL

Very good photo Minnie, THank you for sharing that with us. I always have plenty of extra pop bottles. I may just make one or two to have them handy. I have seen other homemade ones but this way seems to be one of the easiest.

This is a wonderful way to save money yet "fight back"! In early Spring, you will catch queens, and one queen is worth a thousand peasants! lol!
Try using a little bright (red?) food coloring in the water and soap mixture as: the color looks better in the yard,helps hide the dead bodies, and serves as an attractant.
In the Spring, wasps are searching for protein, in the Summer and fall? It's Sweets!
Vinegar mixed in with the water and soap will help discourage honeybees from investigating to their doom~

Clean out the dead wasps if the bodies are piling up...the newly caught wasps may use them as a bridge and a boat to a point of survival!

I used one these traps last year but the wasps never went down into the trap.

If anyone wants to catch and kill aggressive wasps ,especially yellow jackets, and not something beneficial and less aggressive like honey bees DO NOT use juice, soft drinks, and sweet things like that. Use about 1/4- 1/2 cup of red wine and a smidge of dish soap like dawn etc. (measure appropriate to the size container you are using) Believe it or not they are not really attracted to those other offerings and prefer red wine even over white, but do not have expensive tastes so cheap-o stuff works just fine lol. Good luck!
