Attic Insulation Tunnels: Old Damage or Active Shrews? Inspect Before Trapping

Quarter-sized holes and depressed trails in blown-in attic insulation in Richmond, VA. Mouse traps (seeds, cheese, peanut butter) caught nothing. Expert asked: are holes fresh or old? Insulation damage persists years after animals leave.

If fresh: take the free ICWDM inspection course. For shrews, set snap traps perpendicular to trails (blind sets)—they must step on the trigger. Shrew details at the site.

No noises reported—verify activity first. Don't assume an active infestation without current evidence.
