Make sure your trap is specifically intended for squirrels, as the wrong type of trap may cause unintended harm to the squirrel or allow it to escape.

Check your local laws and ordinances to find out if you are able to remove the squirrel from your property, or if you have to release it near your home. Although it’s best to release the trapped squirrel at least 10 miles (16 km) from your home so it’s less likely to find a way back into your attic, this is not always permitted.

These screens will not interfere with the effectiveness of your vents. A general contractor can also help you install the mesh screens, if you’re having trouble doing it yourself.

This allows the smoke to escape your chimney but prevents squirrels from using your chimney as an entrance to your home.
