Squirrel problems should start with proper identification, because the species matters. Different squirrels have different activity patterns, nesting behaviors, entry points, and removal considerations. Correctly identifying what is inside the structure helps determine the safest and most effective approach.

​

Common nuisance squirrels encountered around Pennsylvania homes include:

• Eastern Gray Squirrels – Pennsylvania’s most common squirrel and a frequent attic intruder. They are primarily active during the daytime and often enter through soffits, fascia, roof returns, vents, and damaged roof areas.

• American Red Squirrels – Smaller, highly active and territorial squirrels that may nest in attics, wall voids, garages, and other protected spaces.

• Fox Squirrels – Larger than gray squirrels and found in portions of Pennsylvania. They may use buildings for shelter when suitable access is available.

• Southern Flying Squirrels – Small, nocturnal squirrels that can enter surprisingly small openings and are often mistaken for mice because much of their activity occurs at night.

​

County Pest focuses on determining what species is present, locating active and potential entry points, and choosing the appropriate removal and exclusion strategy. That may include trapping, one-way exclusion where appropriate, repairing damaged areas, screening vents, reinforcing vulnerable openings, and addressing contaminated attic materials.

​

The goal is simple: identify the animal correctly, remove it appropriately, correct how it entered, and protect the structure from future wildlife activity.
