Squirrel Control in Detroit, MI: Expert Removal & Prevention
squirrels may look cute in the park, but when they take up residence in your attic, they become a destructive nuisance. In Detroit's humid continental climate, these rodents seek warm, dry shelter during harsh winters and breeding seasons, often entering through small gaps in eaves, soffits, and rooflines. Once inside, they can cause extensive damage by chewing on wood, insulation, and electrical wiring—creating both costly repairs and a genuine fire hazard.

Who This Is For
This page is for homeowners, property managers, and landlords in Detroit, Michigan, who are hearing scratching or scurrying in their attic, noticing squirrel activity around their roofline, or suspecting an infestation. If you need fast, humane removal and long-term prevention, you're in the right place.
The Problem
Detroit's housing stock includes many older homes with wooden trim, loose soffits, and uncapped chimneys—perfect entry points for squirrels. With a median home value of around $85,000, many homeowners face budget constraints but cannot ignore the damage. squirrels have incisors that grow continuously, so they gnaw constantly to keep them filed down. This means they'll chew through roof sheathing, drywall, and even electrical wires, increasing the risk of a house fire. In fact, the National Fire Protection Association (NFPA) lists rodents as a contributing factor in some residential electrical fires.
Warning Signs
- •Scratching, scurrying, or thumping sounds in the attic, especially at dawn and dusk.
- •Visible entry holes in soffits, fascia, or roofline edges (often 1.5–3 inches wide).
- •Droppings (similar to large rat pellets) in attic insulation or on window sills.
- •Gnaw marks on wood, wires, or plastic pipes in the attic.
- •Nests made of leaves, insulation, and paper in dark corners.
- •squirrels seen entering or exiting under eaves or through vents.
- •Unpleasant odors from urine or decomposing food caches.
Risks of Waiting
- ⚠Electrical fires from gnawed wiring (NFPA data shows rodents cause thousands of home fires annually).
- ⚠Structural damage to roof framing, drywall, and insulation, leading to costly repairs.
- ⚠Secondary infestations of fleas, mites, or ticks carried by squirrels.
- ⚠Contamination of attic insulation with urine and feces, requiring removal and replacement.
- ⚠Increased difficulty of removal if squirrels have established a nest with young.

Treatment Options
Humane One-Way Exclusion
$250–$500We install a one-way door over the main entry point, allowing squirrels to exit but not re-enter. After a few days, the door is removed and the hole is sealed.
Full Exclusion & Repair
$500–$1,500Comprehensive sealing of all potential entry points, including soffits, ridge vents, chimney caps, and eaves. Includes repairing damaged wood, wire mesh, and insulation.
Trapping and Removal
$300–$600Live trapping using cage traps, followed by relocation (where legal). Often used if exclusion doors cannot be placed. In Michigan, relocation must comply with DNR regulations.
Why Detroit Homes Are Vulnerable to Squirrel Invasions
Detroit's humid continental climate brings cold winters (average low 18°F) and warm summers (average high 84°F). squirrels seek attics for warmth in winter and for safe nesting sites during their two breeding seasons (late winter/spring and late summer/fall). The city's older housing stock—much built before 1950—often has deteriorating wood trim, loose soffits, and uncapped chimneys. These features, combined with an abundance of mature oak and hickory trees (which produce nuts that draw squirrels), create ideal conditions for invasion. With 34 inches of annual rainfall, moisture damage can further weaken entry points.
The Humane Removal Process Step by Step
Professional squirrel removal begins with a thorough inspection to identify all entry points and assess activity. We then install one-way exclusion doors over the main entrance—these allow squirrels to exit but not re-enter. A typical exclusion takes 3–7 days; we monitor the door to ensure all squirrels have left. Afterward, we seal the hole permanently with galvanized steel mesh and heavy-duty caulk. If young are present, we may need to hand-remove them and reunite with the mother outside (a delicate process). Finally, we repair any damage and offer insulation replacement if needed. Our service guarantee covers reinfestation from the same entry points for one year.
Squirrel Damage: More Than Just a Noise Nuisance
Beyond the unsettling scratching sounds, squirrels cause real property damage. Their constantly growing incisors require gnawing on hard materials—wood, plastic, and especially electrical wiring. A 2018 industry estimate by the National Pest Management Association (NPMA) indicated that rodent-caused electrical fires account for a small but significant percentage of residential fires in the U.S. In Detroit, where many homes have aging wiring, the risk is heightened. squirrels also tear up insulation for nesting, reducing energy efficiency. Urine and feces can contaminate attic spaces, leading to odor and potential health risks (histoplasmosis is a rare but possible concern from droppings).
How Detroit Properties Should Prepare for squirrel Service
Before a professional visit in Detroit, MI, 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 Detroit squirrel Problems Different
Detroit, MI 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 scratching in your attic, see squirrels entering gaps, or find droppings, call a professional immediately. DIY removal often fails because squirrels are persistent and can re-enter through new holes. Our inspection terms that vary by provider identifies all entry points and provides a clear plan—call 1-888-546-7983.
DIY vs Professional
DIY options like sealing holes or using repellents may provide temporary relief, but squirrels are adept at finding new openings. Spray repellents rarely work long-term, and trapping without knowledge of local laws can lead to fines. Professional exclusion uses proven techniques like one-way doors and heavy-duty sealing materials (steel mesh, caulk, and flashing). In Detroit's climate, a proper seal must also withstand freeze-thaw cycles. The cost of a pro is far less than the damage squirrels can cause in one season.
Local Context
Detroit's urban landscape, with its mix of vacant lots and mature trees, supports a healthy squirrel population. The eastern gray squirrel (Sciurus carolinensis) is the primary culprit. With a population of over 631,000 people, the city's density means squirrels are in close contact with homes. The median home value of $85,000 means many owners are cost-conscious, but ignoring a squirrel problem can lead to thousands in repairs. Our inspection terms that vary by provider helps homeowners understand the scope without upfront cost. Detroit's revival has brought new construction and renovations, but older homes remain vulnerable. Local wildlife control professionals follow Michigan Department of Natural Resources guidelines for humane removal.
Prevention Tips
- ✓Trim tree branches at least 10 feet from your roofline to prevent jumping access.
- ✓Install metal flashing or mesh over soffits, vents, and chimney caps.
- ✓Seal all gaps larger than 1/2 inch with caulk, expanding foam, or steel wool (squirrels can squeeze 1.5 inches).
- ✓Cover attic vents with heavy-duty hardware cloth (not window screen, which they chew through).
- ✓Remove bird feeders or place them far from the house (squirrels love free food).
- ✓Inspect your roofline twice a year (spring and fall) for damage or loose trim.
- ✓Cap chimneys with a stainless steel chimney cap.
