So I move some pieces of wood on the top of the pile, last pile, drying out for 13/14. I see small brown ant colonies, eggs and all, not wood insects, take the pieces they use and drop them on the ground, everyone scatters. Is this a big deal and will it be gone by the winter or is this a problem. They are just small brown ants but if you need pics let me know because I think they will be back.
