Wood Beetle Pest Control Services in Salem, OR

Round exit holes about the size of a pencil lead, often with fine powder below them, are the sign of powderpost or anobiid beetles. The larvae feed inside the wood for years and the adults chew out to mate. Anobiid beetles are the most common wood-boring beetle in Oregon crawl spaces.

Fresh exit holes have clean, light-colored edges and new powder that sifts out when the wood is tapped. Old holes are dark and dusty with no new frass. Because larvae take two to five years to develop, an inspection looks for both current activity and the moisture conditions that allow it.

Anobiid beetles need wood moisture above about 14 percent, which describes many Willamette Valley crawl spaces from November through May. Poor ventilation, missing vapor barrier and plumbing leaks all raise wood moisture. Fixing those conditions is part of every treatment plan.

Accessible wood is treated with a borate product that soaks into the surface and stops larvae as they feed. Severe cases may call for replacing members or, rarely, fumigation. Reducing crawl space moisture with a vapor barrier and ventilation keeps a new generation from starting.

Yes. A wood beetle inspection covers the crawl space, sill plates, joists, subfloor and any exposed framing, plus the moisture conditions that let beetles thrive. We inspect and treat homes in Salem, Keizer, Albany, Dallas, Woodburn and the surrounding valley. Call (503) 362-4539 to schedule.
