I’ve done a lot to attract bees to my garden – planting flowers that they like, building them houses, etc. But carpenter bees? I’m not a fan. They do too much damage to our house, tree house and swing set each year for me to be on good terms with them. I’ve read article after article that says they only go after non-treated, rotting wood, but that hasn’t been my experience at all.

Carpenter Bee Damage

See those holes? They were made by carpenter bees. That’s pressure treated lumber, and they started boring holes in it as soon as we finished building our tree house. They continue to bore new holes in it every spring.

When we built a new roof overhang over the basement a couple years ago, they bored holes through the new cedar supports, before we had a chance to finish them, and they continued to bore holes through them even after we stained them. They’re destructive creatures, I tell you.

So, several years back, my husband and I decided to build some carpenter bee traps to combat the problem. After a ton of research, we came up with our own design, and when we tested them, we couldn’t believe how well they worked.

Here’s a video of one of our carpenter bee traps in action.

Seeing all those carpenter bees in the jar is really satisfying. If you’d like to put these traps to work in your yard, just follow the steps below to build your own, or order some from our shop.
