How do I know if I have squirrels in my attic?
Listen for scratching or scurrying sounds at dawn and dusk. Look for chew marks on vents, soffits, or eaves. You may also find droppings (cylindrical, 3/8 inch long) or nests made of leaves and insulation.
What do squirrels hate the most?
squirrels dislike strong smells like peppermint oil, predator urine, and ammonia. However, these repellents are temporary and not reliable for long-term removal. The only permanent solution is exclusion—sealing all entry points.
Can squirrels cause a fire?
Yes. squirrels gnaw on electrical wiring, stripping the insulation and exposing live wires. This can cause short circuits and electrical fires. The National Fire Protection Association lists rodents as a significant cause of attic fires.

What time of year are squirrels most active in attics?
squirrels are most active in attics during late winter/spring (January–February breeding season) and late summer/fall (June–July breeding season). They also seek shelter in attics during cold Illinois winters.
Will a squirrel leave on its own?
No. Once a squirrel establishes a nest in your attic, it will not leave voluntarily. You must actively remove it using exclusion doors or trapping. Sealing the entrance while the squirrel is inside will trap it, leading to death and odor.
What should I do if a squirrel dies in my attic?
Contact a professional immediately. Dead squirrels decompose quickly, producing a strong odor and attracting flies and maggots. The carcass must be removed, and the area decontaminated.
How common are squirrels around homes?
Almost universal, at least by sightings. In a 2022 survey of 1,006 residents of a southeastern U.S. metro area by Puri and colleagues, published in 2024, 89.1% said squirrels or chipmunks were present in their neighborhood, far ahead of raccoons at 51% and bats at 24.8%. The study combined squirrels and chipmunks in one question, and presence meant neighborhood sightings, not animals nesting in homes. Since squirrels will find any gap in soffits or fascia, an annual look at the roofline is worthwhile.
How much does it cost to remove a dead squirrel from a wall or attic?
Fixr's January 2025 U.S. cost guide estimates dead-squirrel removal at $100 to $250. That is a publisher estimate, not an observed customer bill, and local quotes vary, especially if the animal is inside a wall and drywall has to be opened. The smell usually peaks within a week or two and fades over several weeks. When you call, ask whether the price includes locating the carcass, disposal and deodorizing, since those are sometimes billed separately.
