Need some advice guys - moved into a new home (new to me but built in 1991) about a year ago. Last year I went into the attic and noticed a considerable amount of droppings through out the attic on top of the insulation. Since then I have put glue boards down and contracted with a pest control company who has put bait station in the attic. In the past year there has been no additional evidence of activity as I have caught nothing in the glue boards, the bait is never touched (checked monthly) and I don't hear anything. So maybe this is an old infestation of field mice or something? We do have small grey field mice outside occassionally. I am not sure if its ok from a health perspective for my family to just leave the dropping up there, however there really is a considerable amount and I can't see how to clean it up short of replacing all of the insulation, as its sitting all inside of the fiberglass. What do you guys think?
