I have a remodeled home in Atlanta, Ga. I recently noticed gold colored dust piles beneath my white wood beams on my porch. I don't seen any holes or signs of wood damage but I guess they must be under the wood beam where I see the piles of fine dust material. I did see a bug that looked like the pictures of the powder post beetle. How to I prevent this wood damage from spreading? Does this sound like powderpost beetle damage? Thanks for your reply. L.
