You may think there’s no activity going on in your attic or crawl space. After all, there’s nothing up there but old toys, keepsakes and other collectibles. But an attic/crawl space actually can be a very busy place: rodents love attics, particularly the fiberglass insulation now used in homes today and placed in the attic or crawl space. What’s more, squirrels, chipmunks, even rats also love attics and the old insulation. It’s so warm and pieces of it make a great addition for a nest. It’s so easy to chew on and break into pieces. So easy to move from place to place. In addition, rats and other vermin leave droppings behind. Lots of droppings that can be full of pathogens. Some of which can turn airborne. That’s why it’s wise to take a peek at your attic every now and then to see what’s living (has been living) up there.
