Squirrels become a nuisance when they chew through the facia board or roof and gains access into your soffit and attic. Because they are very social you will normally have more than 4 or 5 making nests.
Raccoons can cause extensive property damage and can be a risk to human health and safety. Small pets as well may be in danger of things including rabies or distemper.
Once nuisance wildlife takes up residence in your home (attic, soffit, wall, crawl space), they are hesitant to leave and can cause extensive damage while establishing their new home.
