Question: What are the tendencies of powder post beetles? Can they live in moisture content of less than 5%? Will they migrate and how?

ANSWER   Some powderpost beetles can survive at moisture contents below 5%, depends on what stage they are in.

When the adult beetle comes out of the wood, they may re-infest that same wood or they may move to another area to lay their eggs. They can also be transported – firewood is the most common method.

When firewood has been stored near the fireplace, adult beetles can come out of the logs and move into some of the wood around the room.  From there the infestation can spread through the house. This is why we recommend keeping wood piles outside and away from the house.  Only bring firewood inside when you intend to burn it.
