How do I get rid of powder post beetles?
Powder post beetles are commonly found in damp dirt floor crawl spaces. One of the things that can be done is laying down a 6mm or greater poly vapor barrier. This will greatly reduce moisture coming up through the ground. The other thing that can help is putting a dehumidifier or heater in the crawl space.
