Pest & Wildlife Issues in the Delaware Valley

Following the path of the Delaware River, the Delaware Valley has many parks and forests. Water sources and wooded spaces sprinkled throughout developed areas are the perfect haven for wildlife. Pests like rodents, bats, squirrels, and raccoons thrive in these conditions.

Q&A with Local Franchisees Rick and Beth Shervais:

What are some of the most common wildlife issues that homeowners face in your area?
We're most frequently called to control squirrels, bats, rodents, birds, woodpeckers, groundhogs, raccoons and skunks.

How do the seasons affect wildlife activity in your area?
In early spring, fall and winter we see more activity in homes, with squirrels, bats and raccoons. Summer provides much more outdoor activity on and under the ground.

What are some common signs of nuisance wildlife activity?
Noises in the attic and fireplaces. Digging under outside structures

Any prevention tips for residents in your area?
If you're trying to do it yourself, be sure to temporarily tape or stuff paper in holes before permanently sealing them, to make certain the animals are no longer inside.Keep trees trimmed back away from roof and secure attic vents. Call a wildlife professional to safely and permanently remove animals.

When should homeowners call Critter Control?
As soon as you hear or see anything on your property that concerns you.

Nuisance Wildlife around Philadelphia


Like many older East Coast regions, The Delaware Valley struggles to control rats and mice. Proximity to water and buildings with plenty of entry holes allow the pests to travel freely and breed rapidly. In homes, a mouse or rat may contaminate food with waste, spread disease, and destroy property.

Bat Colony Removal

During their search for shelter, bats enter attics to roost in large groups. Though helpful in some ways, these animals present a health risk for Delaware Valley residents. Wherever bats rest, their feces collects and may spread illness. Also, a bite or scratch from a bat can transmit the rabies virus.

Squirrel Damage & Squirrel Removal

Several habits put these common Pennsylvania pests in conflict with people. Squirrels hide food for winter in gutters, drains, and attic corners, creating blockages and drawing insects. The rodents will also chew on anything nearby. Beams, wires, and insulation may all show signs of damage.


Adaptable and clever, raccoons have no problem thriving around the Delaware Valley. These pests explore yards, garages, and homes, causing a variety of trouble along the way. A raccoon may den in an attic or loft, tear away siding, fight with pets, or even pass on diseases.
