This page provides problem-solving advice and ways to make your yard or home less attractive to tree squirrels in the first place.
For more information on these small mammals, including what they look like, what they eat and where they live in the forest preserves, visit the main tree squirrels page.
If a squirrel is in your house and you know its location, open a nearby window or exterior door, and close interior doors to limit access inside the house. Left alone, it will find the opening and leave.
Although a squirrel can jump from a second-story window onto a grassy area without harm, a first-floor exit is preferable. Never force a squirrel to jump from the second story. If it cannot leave on its own, set a live trap. Create a foot-long trail of bait leading into the trap, and leave it alone for a few hours. Once the squirrel is trapped, release it outside onto your property. Releasing it on your own property is your only legal option unless you have a permit from the Illinois Department of Natural Resources.
The best way to prevent a squirrel from establishing a nest inside your home is to keep it away from attractive areas from the start.
If a squirrel has already established a nest in your house, try the techniques below, preferably two or three at the same time. After a few days, pack crumpled newspaper into the entrance. If the squirrel is still there, it will pull the paper out. If the paper stays in place for a few days, repair any openings.
Squirrels are not a public health concern. They commonly have sarcoptic mange, but there are no reports of this type of mange passing from squirrels to humans or domestic pets. Squirrels that eat foods high in fat, such as peanuts, are more susceptible. The most obvious sign of mange is a hairless squirrel or one with patches of missing hair.
