Chemical-Free Ways to Get Rid of Carpenter Bees

  • Transcript

    LESLIE: Steve in Illinois, you’ve got The Money Pit. How can we help you today?

    STEVE: Looked outside this year and we’ve got a building that was built in 1929. It’s got a porch above the patio down below. And on the exposed joists, those carpenter bees have put some holes in there. And it – we’re looking for a way to eliminate the carpenter bees and not necessarily poison everything in the neighborhood.

    LESLIE: Well, a part of what they’re doing is – you know, they really enjoy eating this natural wood. So they’re coming there because you’ve got something tasty to offer up. And it turns out that they love to bore these holes that are perfectly 3/8-inches round.

    So you can do a couple of things. You can have it treated by a pest professional and then seal up those holes and that should do the trick. But you’re right: chemicals are used and that might not be what you have in mind.

    The other thing is you can cover that or replace that joist completely – or whatever the support is – with a synthetic wood or a composite that looks like wood but it’s not actually wood. It could be extruded PVC, it could be recycled plastics. This way, it looks like wood; it’s doing the same job that the wood piece was. However, carpenter bees, carpenter ants, termites, whatever pests like to eat a natural source as wood, they’re going to try it, they’re not going to get into it and they’re going to be really confused and fly away and find somewhere else to eat.

    STEVE: Yeah, that sounds like an option. Yeah, I was wondering if there was something that – I assume that painting it would not make a difference. I didn’t know if there was something that could be topically applied to it that would be environmentally friendly and keep the bees out.

    LESLIE: Unh-unh. I’ve had them eat through the painted wood that makes up my entire screened-in porch. And then what happens is they bore a hole but they won’t bore all the way through. They’ll bore into the wood, even if it’s just a 1×6 or whatever. They find a way to bore into it and then bore through the wood itself and lay their eggs in there.

    STEVE: OK. And it – yeah, it’s amazing. It looks like somebody got out with a drill and drilled the hole in there.

    LESLIE: It’s just bizarre. It’s perfect how they do it.

    STEVE: So, essentially, the options, basically, are having someone come out and treat it or either covering or changing the material that’s there.

    LESLIE: Yeah, changing material is usually the best bet because they won’t eat it. And then, as an added benefit, it doesn’t require any maintenance except the occasional cleaning. You’re not going to be painting it all the time. It really is a win-win situation.

    STEVE: OK. Yeah, I’ll look into that. I’ve got a contractor that’s got to come out anyway, so I’ll look into both options. But it sounds like it – I’d prefer something that wouldn’t have to do with pesticides but …

    TOM: Steve, I hope that takes care of those carpenter bees once and for all. Thanks so much for calling us at 888-MONEY-PIT.
