Question: how do you know if you have rats in your home?
Answer: Squeaking or scurrying sounds in the walls. Running or soft footstep sounds primarily at night. Piles of droppings in an area behind a stove, in the basement or attic, or on the ground. Food packages, containers or wooden spoons that have been gnawed on. Rub marks, which look like an accumulation of dirt and grease.
