Squirrel Control in Minnesota: A Complete Guide for Homeowners
If you hear scratching in your attic at dawn or dusk, you may have squirrels. In Minnesota, these agile rodents are more than a nuisance—they can chew through electrical wiring, damage insulation, and create entry points for other pests. Understanding their behavior and knowing when to act is key to protecting your home. squirrels are not just a seasonal problem. With two breeding seasons—February through April and again from July through September—they seek warm, safe spaces to raise their young. Winter shelter drives them indoors as temperatures drop. Acting quickly prevents costly repairs and ensures humane removal.

squirrels enter attics through small gaps, gnaw wires, and breed twice yearly. Humane removal uses one-way doors followed by exclusion repairs. Costs range from $250–$1,500 depending on damage.
Key Takeaways
- →squirrels can squeeze through gaps as small as 1.5 inches.
- →Two breeding seasons mean peak invasions in late winter/spring and late summer/fall.
- →One-way exclusion doors are the standard humane method.
- →Gnawing on wiring creates a serious fire hazard.
- →Professional exclusion and repair typically cost $250–$1,500.
Professional inspection of attic entry points is the first step in humane squirrel removal.
Who This Is For
This guide is for Minnesota homeowners, property managers, and landlords who suspect or have confirmed a squirrel infestation. Whether you own a single-family home in the Twin Cities or manage a multifamily building in Duluth, the principles of exclusion and removal apply. You want clear, actionable information without the sales pitch.
The Problem
squirrels are persistent. Their constantly growing incisors require them to gnaw constantly, and unfortunately, your home’s wood, plastic, and even electrical wiring are fair game. A single squirrel can cause thousands of dollars in damage by chewing through soffits, fascia, and vents. Worse, gnawed wires are a leading cause of attic fires. According to the National Fire Protection Association, rodents are implicated in an estimated 20% of undetermined electrical fires. Beyond physical damage, squirrels carry parasites like fleas and ticks. Their droppings can contain leptospirosis and salmonella bacteria, posing health risks to humans and pets. And because they are territorial, removing one family does not prevent others from moving in unless you seal all entry points. In Minnesota, the combination of cold winters and two breeding seasons means squirrels are especially motivated to find shelter in your attic.
Warning Signs
- •Scratching or scurrying sounds in the attic, especially early morning and evening.
- •Droppings that resemble small, oblong pellets—often found near entry points or in insulation.
- •Gnaw marks on wood, wires, or plastic vents; look for paired grooves from their incisors.
- •Sightings of squirrels entering or exiting soffits, eaves, or roof vents.
- •Nests made of leaves, twigs, and insulation in the attic.
- •Foul odors from urine accumulation or decomposing squirrels (if one dies in the wall).
- •Tracks in dust or insulation leading to entry points.
Risks of Waiting
- ⚠Electrical fires from chewed wiring—a serious safety hazard.
- ⚠Structural damage as squirrels widen existing holes in soffits, fascia, and vents.
- ⚠Secondary infestations: openings made by squirrels invite birds, bats, or raccoons.
- ⚠Health risks from droppings and parasites (fleas, ticks, leptospirosis).
- ⚠Higher repair costs: early exclusion is cheaper than fixing extensive damage.

Treatment Options
One-Way Exclusion Doors
$250-$500Humane devices installed over entry points that allow squirrels to exit but not re-enter. Babies must be removed first if present. After all squirrels are out, the entry is sealed.
Trapping and Removal
$150-$400Live traps placed indoors or outdoors, baited with peanut butter or nuts. Checked daily. Relocation is required, but in Minnesota, it's often discouraged due to low survival rates; exclusion is preferred.
Full Exclusion and Repair
$500-$1,500Comprehensive sealing of all potential entry points—soffits, ridge vents, gable vents, chimneys—with heavy-gauge steel mesh, flashing, or caulk. Includes repair of damaged wood and insulation.
Regional Considerations for Minnesota Homeowners
Minnesota’s climate and geography create unique squirrel challenges. In northern regions like Duluth and the Iron Range, harsher winters drive squirrels indoors earlier and more aggressively. Attics in older homes with wooden soffits and unsealed eaves are especially vulnerable. In the Twin Cities metro area, high population density means more homes in close proximity, which can lead to multiple infestations in a neighborhood as squirrels move from house to house. Southern Minnesota, including Rochester and Mankato, experiences milder winters but still sees two breeding seasons. Rural homes with large trees and nearby woodlots provide abundant habitat, but also increase the likelihood of squirrels transitioning from trees to attics. In all regions, the key is prevention: trimming branches, sealing gaps, and scheduling annual inspections before peak seasons. Local wildlife regulations also vary. In Minnesota, it is legal to trap and relocate squirrels, but relocation is often discouraged because relocated squirrels have a low survival rate and may spread diseases. Most professionals prefer exclusion doors to trapping. Additionally, some cities like Minneapolis have ordinances regarding trap placement and humane treatment, so it is wise to hire a local expert familiar with the rules.
How Minnesota Properties Should Prepare for squirrel Service
Before a professional visit in Minnesota, 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 Minnesota squirrel Problems Different
Minnesota 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
Call a professional if you hear scratching consistently, see squirrels entering your roofline, or find droppings in the attic. DIY attempts often miss entry points or trap animals inside, leading to odors and carcasses. If you suspect a litter of babies, do not seal the entry until they are old enough to leave—a pro can assess and handle this humanely. For Minnesota homeowners, early spring and late summer are the highest-risk times; schedule an inspection before breeding seasons peak.
DIY vs Professional
DIY exclusion is possible for minor issues—sealing a single hole with hardware cloth—but most infestations are more complex. squirrels are intelligent and will find alternative routes if the main entry is blocked. Professionals use specialized tools like one-way doors and can identify all potential gaps, including those hidden behind siding. Moreover, without training, you risk trapping animals inside or separating mothers from young, which is inhumane and can lead to dead squirrels in your walls. For the average homeowner, the investment in professional service (typically $250–$500 for removal, plus exclusion) pays for itself by preventing repeat invasions and costly repairs.
Local Context
Minnesota’s squirrel control needs vary by region. In the Twin Cities (Minneapolis, St. Paul, and suburbs), older homes with wooden eaves and gable vents are common entry points. High tree density in neighborhoods like Highland Park or Linden Hills means squirrels have easy access to roofs. In Duluth, lake-effect snow and cold drive squirrels deeper into attics, often causing damage to insulation and wiring. Rochester, with its newer developments, sees issues around construction gaps and uncapped chimneys. Rural areas in central and southern Minnesota face similar problems but with more space between homes, squirrels may target outbuildings and barns. In the northern pine forests, red squirrels are more common and can be particularly aggressive. Regardless of location, the solution remains the same: thorough inspection, humane removal, and complete exclusion. Many local companies, including ours, offer inspection terms that vary by provider and can provide city-specific advice. Our team serves the entire state, from the Iron Range to the Iowa border.

Prevention Tips
- ✓Inspect your roofline annually: look for loose soffits, gaps around vents, and damaged fascia.
- ✓Trim tree branches at least 10 feet away from your roof to limit jumping access.
- ✓Install heavy-gauge steel mesh over attic vents, ridge vents, and chimney caps.
- ✓Cover gaps around utility lines or pipes entering the attic with metal flashing or caulk.
- ✓Secure garbage cans and remove bird feeders that attract squirrels to your yard.
- ✓Store firewood at least 20 feet from the house and off the ground.
- ✓Use squirrel-proof bird feeders to reduce food sources near the home.
💡 Did You Know?
- ★squirrels perform elaborate fake-burying rituals to fool thieves. They dig a hole, pretend to drop the nut, then cover it up—while actually hiding the nut in their mouth to bury elsewhere.
- ★squirrels can rotate their ankles 180 degrees, allowing them to run headfirst down tree trunks with ease.
- ★a squirrel's front incisors never stop growing; if they didn't gnaw constantly, their teeth would grow into their skull.
