Carpenter bees can infest most wooden elements of the exterior of your home or structure. It is easiest to inspect the these areas during the day. Check wood siding, railings, eaves, fascia boards, fencing, landscape timbers and other exposed wood elements on your property. Look for:
- Half-inch round holes in dry wood, with piles of sawdust underneath
- Dirty yellow streaks of fecal matter staining the wood below the hole
- If a given hole is presently occupied, you will likely find the male buzzing around you when you are near that hole
