How do you get rid of squirrels in an attic?

Removing squirrels from an attic humanely involves sealing off all possible entryways, except for the main entrance, and installing a repeater trap or a one-way door in order to trap them for relocation. Use of fatal methods, such as poisons or kill-traps, inside the attic are not recommended, as they are an ineffective method of permanently preventing the squirrels from re-infesting.

1. Investigate the attic

   Check for any holes that could function as entrances or exits. Squirrels are active during the daytime and can easily be heard. Use this time to identify their movement habits, as sometimes squirrels move between walls that are connected to the attic. If the majority of noises are heard during the night, they are likely due to raccoons or other nocturnal animals.

2. Seal all secondary holes

   In order to keep squirrels and other pests out, all secondary holes must be sealed. Until final repairs can be made, use steel mesh to form a barrier over these holes.

3. Install a repeater trap or a one-way door

   Install a repeater trap over the main hole to trap all invasive squirrels at once. Setting traps inside the attic does not usually work, as squirrels avoid them. A one-way door also works and prevents the squirrels from returning, although it does not allow relocation.

4. Check for baby squirrels

   Mother squirrels often nest in attics due to the security and warmth they provide. If the mother is separated from her young, they have no chance of survival without the assistance of a wildlife specialist. Check regularly for babies until the squirrels are gone.

5. Release trapped squirrels

   Release or relocate trapped squirrels approximately five miles from the house.

6. Clean and repair the attic

   Squirrel droppings and urine are likely to be in the attic following their vacancy. After cleaning, make additional repairs to the holes, and check for electrical wiring damage.
