Can I use a larger bottle?
Do you think it would be an issue if I were to use a 2 liter bottle for example? I figure this way I don't have to touch it for the whole summer. In addition, I've seen some people use juice or a sweet soft drink in their traps. Do you think that would help attract bees? Have you seen your traps catch yellow jackets as well? Thanks for your time.
As long as the top of the bottle fits, you should be able to use a 2 liter bottle. In addition, when there are carpenter bees trapped inside the bottle, the bees release a phermone that naturally attracts other bees.
I do not think the traps catch yellow jackets.
