Quick answer

Squirrel control in North Dakota depends on the season and the species. Tree squirrels like reds and eastern grays invade attics in cold months, while ground squirrels dig burrows. Removal uses one-way doors or live traps, timed around litters. Always check state rules before acting.

Key Takeaways

  • squirrels enter attics through gaps as small as 1.5 inches during two peak breeding seasons (late winter/spring, late summer/fall) and for winter shelter.
  • One-way exclusion doors are the standard humane removal method; never trap and relocate without professional guidance.
  • Gnawing on wood and wiring creates fire hazards; prompt exclusion and repair are critical.
  • North Dakota’s climate drives squirrel activity: cold winters push them indoors, mild springs/falls increase breeding.
  • Professional exclusion typically costs $250–$1,500 depending on damage and entry points; inspection and quote terms vary by provider at 888-546-7983.
  • Research: A homeowner at war with squirrels is in a small camp: 9.3% of metro-area residents reporting squirrels or chipmunks nearby wanted far fewer, in Puri and colleagues' 2022 survey (1,006 respondents, published 2024), which measured neighborhood attitudes rather than infested homes.

The Problem

squirrels are relentless when it comes to entering structures. Their constantly growing incisors drive them to gnaw on wood, drywall, and electrical wiring—creating a serious fire risk. A single squirrel can squeeze through a gap as small as 1.5 inches, often gaining entry via soffits, fascia gaps, or uncapped chimneys. Once inside, they build nests from insulation, leave droppings, and can cause thousands of dollars in damage if left unchecked. In North Dakota, the eastern gray squirrel and fox squirrel are the primary culprits. They breed twice a year—late winter/spring and late summer/fall—coinciding with times when attics provide shelter from the elements. During the winter, they seek heat; during warmer months, they seek safe nesting sites for their young. This seasonal pattern means infestations can escalate quickly if not addressed.

Warning Signs

  • Scratching, scurrying, or thumping sounds in the attic, especially at dawn and dusk
  • Droppings (small, oval, dark) in attic insulation or along rafters
  • Gnaw marks on wood, wires, or plastic (often near entry points)
  • Nests made of chewed insulation, leaves, and debris in hidden corners
  • Entry holes in soffits, fascia, or roof edges, often with greasy rub marks
  • Sightings of squirrels on the roof or jumping from nearby trees to the house
  • Foul odors from urine or decaying carcasses (if a squirrel dies in the wall)

Risks of Waiting

  • Chewed electrical wires can cause house fires.
  • Insulation damage reduces energy efficiency and increases heating bills.
  • Urine and droppings contaminate insulation and create odors.
  • Structural damage worsens as squirrels enlarge entry holes.
  • Young squirrels may die if you seal an entry without knowing.
  • squirrels can attract other pests like fleas or mites.

Treatment Options

One-Way Door Exclusion

Quoted after inspection

A device is installed over the entry point that lets squirrels leave but not re-enter. This is effective for single squirrels or small litters that are capable of moving out. Best when you can monitor activity.

1-2 weeksBest: Attic invasions with a known entry point.

Live Trapping

Quoted after inspection

Cage traps are baited and placed along travel routes. Once caught, the squirrel is removed. This requires checking traps frequently and knowing state rules on release.

Several days to weeksBest: Problem squirrels that avoid one-way doors or for ground squirrels.

Exclusion and Repair

Quoted after inspection

After removal, all gaps are sealed with heavy-duty materials like metal flashing. This prevents future entry and is essential for long-term control.

One-time serviceBest: Preventing re-infestation.

Habitat Modification

Varies

Trimming tree limbs away from the roof and removing food sources like bird feeders reduces squirrel activity around the home.

OngoingBest: Prevention and discouraging squirrels from approaching.

Squirrel Species You'll Meet in North Dakota

In North Dakota, you are most likely to encounter eastern gray squirrels and fox squirrels in urban areas and near woodlots. These are the ones that frequently invade attics. Red squirrels are smaller and more aggressive, often found in coniferous forests. Flying squirrels are nocturnal and can live in colonies, making them a hidden problem in attics. In the western part of the state, ground squirrels like Richardson's ground squirrels are common and cause burrow damage. Each species has different habits. Gray and fox squirrels are active during the day, while flying squirrels are active at night. Ground squirrels hibernate in winter, so they are less of an indoor problem but can damage foundations. Knowing which species you have helps determine the best removal method. A professional can identify the species and tailor their approach.

A Month-by-Month Timeline for North Dakota

January and February are the first breeding season for tree squirrels. You might hear scratching as they prepare nests. By March, young are born, so be cautious about sealing holes. In April and May, squirrels are active, gathering food and expanding their territory. June brings the second breeding season, leading to more litters in July and August. As fall approaches, squirrels start caching food for winter. This is when they might chew into attics to store nuts. October and November are prime times for invasions as temperatures drop. December is quiet as squirrels stay in their nests. For homeowners, the best time to inspect and seal is in late summer before the rush.

What the First Visit from a Professional Looks Like

When you call a squirrel control pro, they will first do an inspection. They look for entry points, signs of chewing, and listen for noises. They will identify the species and estimate how many squirrels are present. They check for babies, especially during breeding seasons. After the inspection, they will propose a plan. This often includes installing one-way doors or setting traps. They will also recommend sealing all entry points after removal. The cost is quoted after this visit, as it depends on the extent of the problem. A good pro will explain the process and answer your questions.

What Affects the Price in North Dakota Homes

The cost of squirrel removal in North Dakota varies. It depends on how many squirrels are in the attic. A single squirrel is easier to handle than a family of eight. The number of entry points also matters. Roofs with many gaps will require more sealing work. Accessibility is another factor. If the attic is hard to reach, it takes more time. The type of squirrel also matters. Ground squirrels might need different trapping strategies. The time of year is important too. During breeding seasons, extra care is needed to avoid separating mothers from babies. Finally, local labor rates and whether the company is licensed affect the price.

Renters, Landlords, and Who Pays for Squirrel Removal

In North Dakota, if you are a renter and find squirrels in your apartment or rental home, the landlord is usually responsible for pest control. However, this depends on the lease agreement. It is best to notify your landlord promptly. Landlords have a duty to maintain habitable living conditions. If squirrel damage makes the home unsafe, they must address it. This includes repairing entry points and removing the animals. As a renter, you should not attempt to remove squirrels yourself, as you might be liable for damages. Document the issue and communicate with your landlord.

Prevention for Older Homes in North Dakota

Many homes in North Dakota were built before 1980, and older homes often have gaps that squirrels can exploit. Check for openings around pipes, vents, and eaves. The foundation may also have cracks. Use durable materials like steel wool or metal flashing to seal gaps. Pay special attention to roof edges and soffits. Trim tree limbs that overhang the roof. If you have a chimney, install a cap. Regular maintenance is key. Inspect your home each fall before the cold weather arrives.

When It Is an Emergency: Squirrel in the House

If a squirrel gets inside your living space, it is an emergency. They can cause panic and damage. Do not try to catch it with your hands. Open a window or door to give it an escape route. Close off other rooms to guide it out. If it is in a wall or attic, it might be less urgent but still needs attention. Chewing wires can lead to a fire, so it is a safety hazard. Call a professional right away. They have the tools to safely remove the squirrel and repair any damage.

When to Call a Professional

Call a professional if you hear persistent scratching, see multiple entry holes, or find droppings. If you suspect a nest with young, a pro can safely remove the family. Professionals are licensed to handle wildlife and know state laws on trapping and release. They also have the equipment to work on roofs and in tight spaces. For ground squirrels that have dug extensive burrows, a pro can implement a long-term plan.

DIY vs Professional

DIY squirrel control often fails because homeowners cannot find all entry points or properly seal gaps. Caulk alone won’t stop a squirrel; it requires heavy-gauge steel mesh and structural repairs. Professionals also use one-way exclusion doors, which are far more effective than traps. While a DIY approach might cost $50–$100 in materials, it rarely solves the problem permanently. For $250–$500, a pro provides a guaranteed solution that saves you time, stress, and potential fire risk. In North Dakota, where winters are severe, a failed DIY job can leave you with frozen pipes and a squirrel still inside.

Local Context

North Dakota’s squirrel population is dominated by the eastern gray squirrel (eastern counties) and the fox squirrel (statewide). In cities like Fargo and Grand Forks, gray squirrels are common in residential areas with mature trees. In Bismarck and Minot, fox squirrels are more prevalent and adapt well to urban environments. The state’s continental climate—cold, snowy winters and warm summers—drives squirrels indoors from October through March, with a secondary peak in August–September when young leave nests. Homes in the Red River Valley, with its older housing stock, are particularly susceptible to entry through rotted soffits and fascia. West of the Missouri River, where trees are sparser, squirrels often target barns and outbuildings. Local regulations require that any trapped squirrel be released within 24 hours on the same property or humanely euthanized. Professional services in North Dakota typically offer inspection terms that vary by provider and will advise on the best course of action based on your specific situation. Whether you’re in a suburb of Fargo or a rural farm near Williston, the principles of exclusion and prevention remain the same: seal all gaps, eliminate food sources, and trim branches. For city-specific guidance, contact a local professional. Squirrel Removal services the entire state, with technicians familiar with regional building styles and squirrel behavior. Call 888-546-7983 to schedule a inspection terms that vary by provider and get a customized plan.

Prevention Tips

  • Inspect your roof and fascia for gaps or holes in the fall.
  • Trim tree branches that are within 6 to 8 feet of your roofline.
  • Install metal flashing around the base of chimneys and vents.
  • Use heavy-duty wire mesh to cover attic vents and soffits.
  • Remove bird feeders or place them on poles with baffles.
  • Keep garbage cans sealed and store pet food indoors.
  • Check for signs of digging in your yard and fill burrows.
  • Consider having a professional inspect your home annually.

💡 Did You Know?

  • squirrels use fake burials to deceive thieves: they dig a hole, cover it, then scamper off to hide the nut elsewhere.
  • squirrels can rotate their ankles 180 degrees, allowing them to climb down trees headfirst without turning around.
  • a squirrel’s front incisors grow about 6 inches per year, which is why they gnaw constantly to keep them short.

Frequently Asked Questions

How can I tell if I have squirrels in my attic?
Listen for scratching, scurrying, or thumping sounds, especially at dawn and dusk. Look for droppings (small, oval, dark) in insulation, gnaw marks on wood or wires, and nests made of chewed debris. You may also see squirrels on your roof or jumping from trees to the house.
What is the best way to get rid of squirrels humanely?
One-way exclusion doors are the standard humane method. They allow squirrels to leave the attic but prevent re-entry. After all squirrels have exited (usually 3–7 days), the entry point is permanently sealed. This avoids trapping and relocation stress.
How much does professional squirrel removal cost in North Dakota?
Typical costs range from $250 to $500 for simple exclusion, up to $1,500 for full exclusion plus repair of damage. Factors include number of entry points, severity of damage, and attic accessibility. inspection and quote terms vary by provider at 888-546-7983.
Can squirrels cause a fire in my home?
Yes. squirrels gnaw on electrical wiring to keep their incisors trim, which can strip insulation and cause short circuits or sparks. According to the National Fire Protection Association, rodents are a contributing factor in many attic fires.
Do I need a permit to trap squirrels in North Dakota?
Yes, if you are trapping and relocating. North Dakota Game and Fish regulations require that trapped animals be released within 24 hours on the same property or humanely euthanized. Professional services handle permits and compliance.
How can I prevent squirrels from coming back?
Seal all gaps larger than 1.5 inches with steel mesh or metal flashing. Trim tree branches at least 6 feet from the roofline. Install chimney caps and vent screens. Remove bird feeders that attract squirrels, or use baffles.
What should I do if I find baby squirrels in my attic?
Do not remove them yourself. Call a professional immediately. The mother will retrieve her young if a one-way door is used correctly. If the young are separated, they may die in the walls, causing odors and attracting pests.
Is it safe to use poison to kill squirrels?
No. Poison is inhumane and illegal for nuisance wildlife in North Dakota. It can also kill pets, birds, or other animals that eat the poisoned squirrel. Additionally, a dying squirrel in a wall will rot and cause a foul odor.
