How do I exterminate powder post beetles?
I am remodeling a bathroom, and I found powder post beetle residue behind shower stall.
For powder post beetles, we would recommend using Boracare. The wood you are applying this product to must be untreated, meaning no sealants. You will use 1 gallon of Boracare with 1 gallon of hot water. You can either spray the wood or paint it on. Once the product is dry, you can apply any type of sealants to the wood.
