Common Types of Squirrel Damage

Squirrels can cause a great deal of damage to both the interior and exterior of your home. Squirrels damage usually comes from their chewing and gnawing.

Squirrels can squeeze through a hole the size of a golf ball. Squirrels chew through soffits, fascia boards, siding, wood, metal, and shingles to gain access to your attic. Once inside your home, squirrels damage attics by chewing wires, ripping up insulation, and defecating in the attic.

Squirrel Droppings and Your Health

Squirrel droppings can also harm your health. Mold and fungus can grow in their droppings. Diseases like leptosriosis and Salmonellosis are spread via animal waste. Finally, ectoparasites like fleas, ticks, bed bugs, and chiggers introduced by a wild animal can spread diseases to you and your family. 

What Can You Do About Squirrel Damage to Your Property?

You need to repair all the damage done. Entry points leave you vulnerable to future wildlife infestations. Chew pipes and wires are hazards. Soil insultation are breeding grounds for diseases. 

But before you can repair the damage, you must evict the squirrel. Generally squirrel repellents like capsaicin are ineffective long term solutions. The most effective means of squirrel control is to trap, remove and exclude the squirrel.
