You might hear scratching at night, find droppings, or notice something has been chewed. The challenge isn’t just getting rid of them. It’s figuring out what kind of rodent you’re dealing with in the first place.
There are several common rodents in homes, and each one behaves differently. Some stay in the attic, others stick to kitchens or basements.
