I have been seeing these tiny little brown bugs all around the wood window sills and around the fireplace and door entry ways. They look like a spot of sand, they are easily squished with my hands. I tried to take some pictures but they dont look like anything based on the resolution. I know this is a broad description but does anyone know of any bugs like this around this time? I'll keep trying to take pictures and hope one comes out. I live in the Northeast (Boston), thanks guys.
