You Discover Clumps of Shredded Paper
Discovering little piles of shredded paper should send up a red flag. Those clumps are a sign that rodents are moving into your house. Mice and rats make nests from shredded paper, cardboard, or even fabric.
Don’t lull yourself into thinking that it’s just a few mice: A female mouse can give birth to five litters in a single year, so a couple of mice can quickly turn into dozens of mice, which can create a health hazard in your home.
You can try using no-kill traps to catch the little critters and transfer them safely out of doors, but if you continue to find rodent nests or droppings, you should call an exterminator.
