    Default Carpenter Bee Trap

    While inspecting a big log home this week I came across a device I have never seen. The owner had them installed around the home, at first I thought they were just a bird house but the caretaker of the property explained that they were Carpenter Bee traps. The bees go in the holes or bore their own hole and then head for the light (glass jar) at the bottom of the trap. Also the wood on the trap is bare or not treated with anything, the bees like it better than the logs that have been treated. Once in they can not get back out!

    They really work because I did not find one hole from a bee on this home.

    Ahh, but were there any bees in the jars? What was the mechanism that kept the bees from backing out?

    They had many in the bottom of the jars, you can see them if you zoom in on the photos. As for what keeps them from backing out? They are dumb!

    Talking Re: Carpenter Bee Trap

    I've found if I seal the holes with construction adhesive, problem solved. The bugs inside remain entombed waiting on Geraldo Rivera while their friends outside go play somewhere else when they get sticky feet.

    Keep the fire in the fireplace.

    Resurrecting an old thread rather than create a new one.

    Two years ago, while on vacation in North Carolina, we stopped at a hardware store and found an interesting item - a carpenter bee trap.

    Being as we had a number of carpenter bees around our house in Florida, we bought one. I put the carpenter bee trap up then forgot about it.

    Last year I noticed it and thought, oh well, it works some, but not much (there were two bees in it as I recall). I emptied it and put it back up.

    Last month I noticed it again and ... man, that things works!

    See photos.

    When I bought the Carpenter bee trap, I had forgotten that Scott posted about one 8 years earlier, I did a search before creating a new thread and ... there was Scott's posts showing the same thing!

    JP, when you are done painting the little numbers on their backs, could you supply some critical info?
    What is the diameter of the hole?

    We actually don't have infestations of them here, but how would we know if nobody is trapping them?

    I would guess 3/8-1/2 inch......I freaking hate those things and it is amazing how much damage they can do in just 5-10 years. I have literally heard them chewing on the fascia boards on my home, and you will literally see small amounts of saw dust drifting down as well. Active holes will have pollen staining around it more often than not (or at least around here)

    Without going out to measure, as Mike said, 3/8" to 1/2", I think the holes are just barely short of 1/2" as in the past I used 1/2" by 1-1/2" lags (the shortest I could find) and plugged the holes with those, sometimes the lags barely grabbed the wood, which is why I suspect the holes are almost 1/2".

    I can go out and measure if needed, but ... this should answer that question: Making Carpenter Bee Traps: 6 Steps (with Pictures)

    Cut and Paste:

    The trap is a simple wooden box with 1/2" holes drilled in all 4 sides at an upward angle. Since the bees prefer to use an existing hole, these traps provide the hole they are seeking. Once inside the box, the bees fly toward the light and end up in the plastic water bottle at the bottom. Two things I saw mentioned online were that these bees like an overhanging roof and a sloped side to the box. I included these design elements by providing an oversized roof and angling 2 sides of the box.
