Do you think that would work for yellow jackets too?

Nice trap. I have 3 that I put out every season. They really work well. Carpenter bees, wasps, even a green tree frog – though I have no idea how he managed to fit through the hole.

Is that cedar or pine? The folklore in this part of Kentucky is that cedar is the only wood that works.

Theory is the carpenter bees go in the hole – same size as they like to bore out – looking for a place to lay eggs/fertilize. Once they get in they see all the light coming from below in the jar and they head toward it, kind of like a fly in the window. It’s so bright down there they never try to come up and find the hole they came through. Magic formula seems to be wood type and hole diameter, you get those right and bingo. The oddball wasp, yellow jacket or apparently tree frog? only goes in by chance, the carpenter bees are actually looking for those kinds of holes in the wood.

So what is the hole size? I’ve had them bore dozens of holes into the fascia of my back yard shed. I’m seeing about 3/8”?

Thank you all for your interest and comments on my Carpenter bee Trap.

Hole is about the size of your Pinky about 1/4-3/8 depending on what you find already in your yard.

Yellow Jackets will not go in . Like Wasp they want to build their own homes were carpenter bees want to burrow into wood. the fresher the pine board the better to attacked them.

My instructions stated a 1/2 hole (which is about your pinky size) close to the top angled up. The opening at the bottom has to be small enough that they cannot get back out. The angle of the hole and the size of the top are to provide protection from the elements. The bees are picky about protection from the elements. Though some do not have fluid in the bottom of the jar, my instructions stated a 1/2 mix of water and liquid soap – eliminates the bubble of air on the insect and causes them to drown.
