A squirrel in a chimney may sound like gnawing since they like to chew through a wide range of materials. You may also hear a persistent scratching sound if they’re trapped inside and unable to get out themselves. Other evidence of a squirrel in your chimney includes holes on or around your chimney as well as droppings or damage to roof shingles or wiring.

Generally, squirrels are not considered aggressive toward humans. They are more likely to flee than confront people. However, like many animals, they may exhibit aggressive behavior if they feel threatened or cornered. If you approach a squirrel too closely or try to handle it, especially if it's a mother protecting her young, it may resort to defensive tactics such as biting or scratching.

Some of the best smells for keeping squirrels away are those that have a spicy or pungent odor. This includes pepper, garlic powder, vinegar, mint, and coffee. Just be careful when handling cayenne or chili pepper. Don’t touch your face to prevent getting some in your eyes, and be sure to keep it away from children and pets.
