I have a serious problem with Carpenter Bees. When is the best time to apply the dust in the their holes? I have a number of holes to do this to and if it will stop them from boring holes out of my home in the spring, I want to do it now. Note there are areas I have already filled with a wood-accepting bondo product. Over these areas I have applied a three-coat oil-based paint over them. Let me know (1) when is the best time to apply the dust (noting its fall now in New England. (2) will they bore out of holes I have already plugged?

Just added a carpenterbee video playlist page which features some excellent closeup footage of them in action. Some of the other videos included show how to use the various equipment needed and how to treat their nests.

Hi, I am contacting you to inquire about what product and equipment you can recommend to get rid of bees that living under my wood siding. Is this a job I can do myself or should I just call a professional.

To whom it may concern …
My carpenter bee problem exists below my untreated wood deck. The homes they’ve created are not the floor boards, but rather the joists underneath the floor.

I see some bees hanging around my shed and I’m not sure what species they are. First I thought they were honey bees but I noticed they’re mostly yellow and black. Then I saw a hole which could be an old wood knot but its so perfect, I think someone drilled it. Well, the bees are using this hole as a nest! I see them going in and out. The hole is in one of the 2×4 studs which I can rip out but I’m afraid of getting stung without treating first. Any idea what type of bee this might be?

I own a log home restoration company. I treat log homes with timbor (after I strip the logs, but before I apply the new stain) as a preventative against wood boring insects and fungi as part of my restoration process, and when I run into carpenter bees I use Drione dust in the holes and seal them with chinking. I haven’t figured out how to stop the bees from boring new holes after I’ve finished the job until I read about Cypermethrin. What I’d like to know is how do I use this product in conjunction with Timbor?
Thank You.

I need some help. I am looking at the Drione Dust 1lb vs the PT-230 Tri Die 8z. I have 2 nests of carpenter bees in my soffits and I don’t know which product I should purchase. I will need to treat again next year. But I was not sure which product I should use. your advise would be appreciated.

I have bumble bees coming into my sunroom throughout the day, I always manage to get the window open and let them out, there is a deck attached to the sunroom but I am not sure if that is where the nest is. I let 3-4 out the window every day. Not sure what to do since I do not know if they are in the wall or coming from the deck area. I only get one bee at a time (Thankfully). Any suggestions would be greatly welcomed as I know it is only a matter of time before me or my cats get stung.

I need to get rid of carpenter bees that are drilling into my deck. I see at least 5 holes but suspect there could be more. When do they drill their holes? I never saw anything happening. The only reason I even found the holes is because there was a lot of powder on the patio under the deck. It looked like someone was drilling holes there was so much powder and when I looked closer, I could see perfectly clear holes in several floor planks of my deck. Do I need to replace them and what can I do to get rid of them?

I’ve had an ongoing problem with carpenter bees drilling holes in overhangs that are on all sides of my house. I’ve been spraying with the Cypermethrin and it’s worked quite well but I’m wondering if there is something I can do that’s more permanent. What if I add some to the paint I use on my trim and siding? How much would I need? I generally paint every 4-5 years (a lot of touch up for sure) and if there is any way I can incorporate a chemical with the paint I’d do it.

THANK YOU for the great info on these cute but annoying creatures who have infested my porch beams…..will spraying insulating foam sealant into the holes do the job of caulking or corks? If so, that would sort of reinforce the holes as well as trap the bees after spraying. What should I do about the holes the bee has already sealed? I assume the wasps loitering around are trying to get to the newly laid eggs at this time of the year and are establishing nests to be near to take advantage of the hatching bees in the fall.

I’m going to be doing some treating with drione for carpenter bees and I’m wondering if I need a bee hat or veil or some kind of protection?
Generally speaking, you won’t need any special protective bee equipment when treating for carpenter bees. As our Carpenter Bee article explains, the Male bees don’t have stingers and females generally are not agressive. When treatments are done late in the day, around dusk, or early in the morning, we have not heard of anyone having problems. That being said, we do have Bee Suits, Bee Veils and Bee Hats available if you feel such protection would be desired.
