Often referred to as nuisance wildlife, squirrels present their own unique set of dangers when it comes to their interaction with humans as they can become aggressive when they feel frightened or threatened. While people should be cautious year-round, squirrels tend to be more of an issue in fall and winter as the weather becomes colder and they look for a place to stay warm. During these months, our homes become an ideal shelter for squirrels, and this can be a problem, as squirrels will gnaw at wires, insulation and damage walls.
Where do squirrels live?
In general, squirrels nest in tree cavities or build nests in tree branches during the warmer months. When it is colder, squirrels may live in tree holes, but are also known for invading homes and structures to keep warm.
Are squirrels dangerous to humans?
It is unclear if squirrels pose a health risk to humans. While some people claim that squirrels carry diseases, others say that they do not carry any harmful diseases that can be transferred to humans. That said, it is best to take precautions and avoid contact when possible. If you do get bitten, seek immediate medical attention.
Are squirrels a threat? How can I prevent a squirrel infestation?
Squirrels are considered to be pests as they can damage electrical wires and telephone lines outdoors. They also enter homes in the colder months to keep warm, where they can gnaw at wires, insulation or walls and make a lot of noise. To help prevent a squirrel infestation, it is recommended to:
- Seal all possible points of entry around the house, including small openings and cracks around doors and windows.
- Screen vents and openings to chimneys.
- Keep food in airtight containers and dispose of garbage regularly.
- Keep tree limbs cut back 6 to 8 feet from the roofline.
