There shouldn't be a need to touch the squirrel, but if you end up doing so, make sure you wear heavy-duty gloves. Squirrels may nip and scratch, and it's important to protect yourself. If you release the squirrel too close to your property, it will climb right back into the attic. Drive well away from your neighborhood and release the squirrel in an area with plenty of trees. If you somehow trapped both the babies and mother, try to release them all in the same place. The babies will have a much better shot at surviving if they're released with their mother. After you've released the squirrel, sanitize the area where you found it using heavy-duty cleaning products. Make sure all of the entry holes are secured. Consider spraying squirrel repellant in the area on the off chance that the squirrel will try to come back.

Summary:
Don't handle the squirrel with bare hands. Release the squirrel 510 miles (8.016.1km) away. Release the babies and mother together. Clean the area where the squirrel was trapped.
