If you have a wood-burning fireplace with an uncapped chimney, there is a chance wild animals may have moved in. How do you know? Listen carefully: You'll hear scratching, movement and even yelping from babies. Animals like raccoons, squirrels, bats and birds are all candidates to take nest in your chimney. If you suspect you have an animal living inside, don't start a fire. When you lift the damper (where they often roost), you risk having them fall down the chimney and into your home. Instead, contact wildlife control to help you safely remove the animals. Then cap the chimney so this doesn't happen in the future.
