insect sawdust between double paned glass
At our house in Grand Lake, there is a pile of sawdust between the panes of the double-paned glass. Do you know what this is from? I am thinking carpenter ants or wood beetles. We have not seen any insects and the only evidence is this pile of sawdust. What do we do about it? We are thinking we must replace the glass but then what do we do for the underlying problem?
Nevermind... our glass contractor said it is silicon beads that are from the window seal. Not an insect.
