Quick answer: Powderpost beetle treatment depends on the extent of damage — localized borate treatment works for small, accessible infestations, while widespread structural damage may require fumigation.
Powderpost beetles lay eggs in the pores of unfinished hardwood, and the larvae tunnel through the wood for months or years before emerging as adults, leaving behind fine, powder-like frass and pinhead-sized exit holes as the giveaway.
Because the damage happens inside the wood, an infestation in flooring, furniture, or structural beams can be well underway before it’s visible from the surface.
We assess the extent of damage, identify active exit holes versus old ones, and apply targeted borate or fumigation treatment depending on the wood type and location, with follow-up monitoring to confirm the infestation is fully stopped.

Fresh frass (fine wood powder) beneath exit holes signals active activity; old, dusty holes with no powder buildup usually mean it's run its course.
Yes, especially unfinished or antique wood furniture, which is why we inspect nearby pieces during treatment.
Not always — localized borate treatment works for smaller, accessible infestations, while fumigation is reserved for widespread damage.
