Delaware Squirrel Control: Expert Removal & Prevention
If you hear scratching, scampering, or gnawing in your attic, it's likely gray squirrels—the most common squirrel species in Delaware. These agile rodents are expert climbers and can squeeze through surprisingly small openings. Beyond the noise, they cause real damage: chewed wires, torn insulation, and contaminated spaces. Acting quickly prevents costly repairs and health risks.

Who This Is For
This page is for Delaware homeowners, property managers, and landlords dealing with squirrel intrusions. Whether you're in Wilmington, Dover, or Sussex County, the information here applies statewide. If you suspect squirrels in your attic or have seen them entering your roofline, you'll find practical steps and professional resources to resolve the problem.
The Problem
squirrels may look cute in the park, but in your attic they are destructive pests. Their incisors never stop growing, so they gnaw constantly on wood, drywall, and electrical wiring. Chewed wires are a leading cause of attic fires. They also tear up insulation for nesting, leaving urine and droppings that can harbor bacteria and allergens. In Delaware, the eastern gray squirrel (Sciurus carolinensis) is the primary culprit, with populations dense in both urban and suburban areas.
Warning Signs
- •Scratching, scurrying, or gnawing sounds in the attic, especially at dawn and dusk.
- •Droppings (small, oblong, dark) in the attic or near entry points.
- •Chewed soffits, fascia boards, or roof vents—often with tooth marks.
- •Insulation disturbed or pulled apart for nesting material.
- •Nests made of leaves, twigs, and insulation in attic corners or eaves.
- •Sightings of squirrels entering gaps under eaves, around pipes, or at rooflines.
- •Strong, musky odor from urine accumulation in insulation.
Risks of Waiting
- ⚠Electrical fires from gnawed wiring—a genuine safety hazard.
- ⚠Structural damage as squirrels widen entry holes and chew support beams.
- ⚠Contaminated insulation that may require costly removal and replacement.
- ⚠Secondary infestations of fleas, mites, or ticks carried by squirrels.
- ⚠Increased difficulty and cost of removal if squirrels breed and establish a nest.

Treatment Options
One-Way Exclusion Doors
$250-$500A humane device fitted over the main entry point that allows squirrels to exit but not re-enter. Once all squirrels are out, the door is removed and the hole is sealed.
Trapping and Relocation
$300-$600Live traps baited with nuts or peanut butter. Trapped squirrels are relocated to suitable habitat far from the home. Requires permits in Delaware and is usually combined with exclusion.
Full Exclusion and Repair
$500-$1,500After removal, all gaps larger than 1.5 inches are sealed with heavy-gauge steel mesh, caulk, or metal flashing. Damaged wood, soffits, and vents are repaired. Includes chimney caps and vent covers.
Understanding Squirrel Behavior and Entry Points
Eastern gray squirrels are diurnal, most active in early morning and late afternoon. They are excellent jumpers, capable of leaping 10 feet horizontally. Their sharp claws let them climb brick, wood, and metal downspouts. Once on the roof, they target weak spots: loose soffits, uncapped chimneys, and gaps around plumbing vents or roof edges. A gap of just 1.5 inches is enough for an adult squirrel to squeeze through. They often gnaw to enlarge openings, making matters worse. Inside, they build nests in insulation, chew electrical cables, and store food. They have two breeding seasons: late winter (February–March) and late summer (July–August). During these times, females seek safe, warm spaces for their litters. That's when attic invasions peak.
The Fire Hazard of Gnawed Wiring
squirrels' incisors grow continuously—about 6 inches per year. To keep them trimmed, squirrels gnaw on hard materials. In attics, electrical wires are a prime target. Chewed wires can short-circuit, spark, and ignite nearby insulation or wood. According to the National Fire Protection Association, rodents are a contributing factor in an estimated 20,000 house fires annually in the U.S. While exact figures for squirrels alone are not tracked, fire departments and pest control professionals consistently report wiring damage during squirrel infestations. This is why prompt removal is critical—not just for noise reduction, but for fire safety. After removal, a professional should inspect all visible wiring for damage.
Humane Exclusion: The Gold Standard
One-way exclusion doors are the most effective and humane removal method. A device is installed over the main entry hole. It allows squirrels to exit but prevents re-entry. The door is left in place for several days to ensure all animals have left. During breeding seasons, professionals must check for babies—if young are present, they may need to be reunited with the mother after exclusion, or removed by hand and placed in a heated box for relocation. After confirmation that all squirrels are gone, the entry hole is permanently sealed with galvanized steel mesh and caulk. This method avoids killing and is recommended by wildlife agencies. It also ensures that no animals are trapped inside to die and cause odor problems.
Delaware-Specific Considerations
Delaware's moderate climate and abundant tree cover make it ideal for gray squirrels. In northern New Castle County, suburban neighborhoods with mature oaks and maples see frequent invasions. The Piedmont region's older homes often have complex rooflines with many potential entry points. In central Kent County and southern Sussex County, agricultural and wooded areas support high squirrel populations. Coastal areas like Rehoboth Beach also have issues, especially in rental properties that sit vacant off-season. State regulations require that trapped wildlife be released on the same property or euthanized—relocation to distant sites is discouraged due to disease transmission concerns. A licensed professional knows the rules and follows best practices.
How Delaware Properties Should Prepare for squirrel Service
Before a professional visit in Delaware, clear access to baseboards, utility areas, kitchens, bathrooms, garages, crawl spaces, and any location where activity has been seen. Take photos of sightings, save damaged materials when safe, and note when the problem is most active. This helps the technician confirm the species, find nesting or entry points, and choose a treatment plan that matches the property instead of relying on a generic spray-and-leave visit.
Questions to Ask Before Booking squirrel Control
Ask whether the inspection is included, what treatment methods are being proposed, how follow-up visits are handled, and what conditions could change the price. For rental properties, restaurants, hotels, warehouses, and multi-unit buildings, ask whether documentation is provided after service. Strong providers explain the source of the problem, the treatment area, safety instructions, and prevention steps in plain language before work begins.
What Makes Delaware squirrel Problems Different
Delaware properties can have different pest pressure from block to block because of building age, landscaping, moisture, trash handling, nearby food sources, and how tightly entry points are sealed. A good inspection does not assume every property needs the same service. It checks the structure, surrounding conditions, activity level, and safety needs before recommending treatment.
Inspection Steps for squirrel Issues
A complete inspection should look at interior activity, exterior entry points, moisture conditions, food or harborage sources, nearby vegetation, storage areas, and any connected units or shared walls. The best inspection notes where activity is confirmed, where it is suspected, and what needs to change after treatment so the same issue does not return quickly.
Follow-Up and Prevention Plan
Professional pest control should not stop at one visit when the infestation risk is ongoing. Follow-up timing depends on the pest, severity, season, property type, and whether sanitation or exclusion work is still needed. A practical prevention plan may include sealing entry points, improving drainage, trimming vegetation, changing storage habits, and monitoring activity after service.

When to Call a Professional
If you hear consistent activity in the attic, see entry holes, or find droppings and damage, call a professional. squirrels are fast and can cause extensive damage in days. Attempting removal yourself risks injury from bites or falls, and improper exclusion can trap animals inside. Squirrel Removal offers inspection terms that vary by provider—call +1 888 546 7983 to schedule.
DIY vs Professional
DIY methods like setting a live trap or sealing a hole might work for a single squirrel that wandered in by accident. However, most infestations involve a family or multiple animals. Without proper exclusion, new squirrels will find the same entry points. Professionals use one-way doors that ensure all animals are out before sealing, and they have the equipment to safely access high rooflines. The cost of a pro is often less than the damage DIY mistakes can cause.
Local Context
Delaware's three counties each present unique squirrel control challenges. In New Castle County, especially Wilmington and Newark, dense suburban neighborhoods with large trees mean squirrels easily access roofs via overhanging branches. Older homes in historic districts often have unsealed eaves and uncapped chimneys. In Kent County, Dover and surrounding areas have a mix of older and new construction; agricultural fields provide food, driving squirrels toward attics for shelter. Sussex County's coastal towns (Rehoboth, Lewes, Bethany) see seasonal population spikes—vacation homes left empty in fall become prime targets as squirrels prepare for winter. Regardless of location, the principles are the same: seal all gaps larger than 1.5 inches, trim tree limbs, and remove attractants like bird feeders. Professional help is available statewide through Squirrel Removal, which serves all three counties. Call +1 888 546 7983 for a inspection terms that vary by provider.
