hi all im new to this. I have a decent stack near my house for burning this winter. I was moving it around and when I got to the bottom I notice little piles of saw dust. I didn't see any ants but with some searching on line best I can figure is there carpenter ants. The stacks are between my barn and house. what can I do to get rid of the and make this wood ok to burn in my home with out infesting it. thank you
