Quick answer

In Washington, DC, squirrels enter attics through gaps near roofs and eaves. Remove them with one-way doors or trapping, then seal entry points. Act before late winter and mid-summer litters to avoid trapping young inside.

Key Takeaways

  • squirrels enter attics through gaps as small as 1.5 inches, especially during two breeding seasons.
  • Gnawing on electrical wires is a leading cause of attic fires; prompt removal is critical.
  • One-way exclusion doors are the standard humane method; sealing all entry points prevents re-entry.
  • DC's urban tree canopy and historic row homes create ideal squirrel habitats.
  • Professional removal costs $250–$500; full exclusion and repair can range up to $1,500.
  • Research: Fixr's January 2025 U.S. squirrel-removal guide puts a typical project at $350, but that is the publisher's estimate, not a verified transaction price or a current quote in any particular market.

The Problem

In Washington, DC, squirrels find plenty of food in parks and yards, but they also find warm, dry attics in row houses and older homes. The District's temperate climate means activity almost year-round. Gray squirrels are the main attic invaders, but flying squirrels also move in during colder months. They chew through wood, fascia, and vents, causing damage and fire hazards from gnawed wires. Winter lows near 28F rarely freeze the District solid, so squirrels here do not go quiet for long stretches the way they do farther north, and calls keep coming through January.

Warning Signs

  • Scratching, scurrying, or thumping sounds in the attic, especially morning and evening.
  • Droppings that are elongated, about 1/2 inch long, often near entry points.
  • Gnaw marks on wooden beams, electrical wires, or plastic pipes.
  • Nests made of leaves, twigs, and insulation in attic corners or behind walls.
  • Acorn shells, nuts, or food debris stored in vents or gutters.
  • Visible damage to soffits, fascia, or roof edges where squirrels have chewed through.
  • Squirrel sightings on the roof or near attic vents, especially during breeding seasons.

Risks of Waiting

  • Electrical fires from chewed wiring: squirrels strip insulation, exposing live wires.
  • Structural damage from repeated gnawing on wooden supports and rafters.
  • Health risks from droppings and urine, which can contain leptospirosis or salmonella.
  • Secondary infestations by fleas, mites, or ticks brought in by squirrels.
  • Increased exclusion costs as damage worsens and more entry points open.

Squirrel Species You'll Meet in Washington, DC

In DC, you're likely dealing with eastern gray squirrels, the most common tree squirrel in the region. They're active during the day, and their nests, called dreys, are often in tall trees. Fox squirrels are also present, especially in parks and wooded areas. They're larger and more tolerant of urban settings. Flying squirrels are the surprise guests. They're nocturnal, so you might hear them at night. They're smaller and can fit through tiny gaps. Many homeowners mistake them for mice. Knowing which species you have matters because flying squirrels may require different exclusion methods. DC's temperate climate and mature trees provide ideal habitat. With many older homes, there are plenty of entry points. If you see squirrels around your roof, they may already be looking for a way in.

A Month-by-Month Timeline for Squirrel Activity in DC

squirrels are active year-round in DC, but their breeding seasons drive attic invasions. The first litter is born in late winter, around February. That means pregnant females are seeking den sites in January. The second litter arrives in mid-summer, around July or August. In the fall, squirrels are busy caching food, which may increase chewing as they test your home for food storage. Winter is when flying squirrels often move into attics for warmth. Even in DC's mild winters, cold snaps push them indoors. If you hear noises in December or January, it could be flying squirrels. Understanding this timeline helps you plan. If you need exclusion, avoid sealing entry points during breeding seasons unless you're sure no young are inside. A professional will inspect for litters and wait if necessary. Roughly 40 inches of rain a year keeps Washington, DC roofs damp, and softened plywood at a leaking flashing seam is exactly the spot a squirrel will test with its teeth in a wet spring.

What the First Visit from a squirrel Control Pro Looks Like

When you call a professional in DC, they'll start with an inspection. They'll walk your property, look at your roofline, attic, and any potential entry points. They'll ask about noises, sightings, and droppings. Then they'll identify how squirrels are getting in. Next, they'll recommend a removal plan. This might be one-way doors or trapping. They'll explain the process, timeline, and what to expect. They'll also discuss any permits needed for DC. After removal, they'll seal entry points and may offer repairs for damage. Ask for a written plan and estimate. A good pro will also advise on prevention, like trimming trees and securing vents.

What Affects the Price of Squirrel Removal in DC Homes

The cost of squirrel removal in DC varies with your home's size and age. Row houses may have more access points from adjoining buildings. Older homes often have looser fascia or gaps around chimneys. The number of squirrels and whether young are present also affect price. If you need repairs for chewed wood or wires, that adds cost. Your location in DC matters too. Some neighborhoods have more trees, which can mean more squirrel activity. The type of removal method, one-way doors versus trapping, influences pricing. Permits and professional licensing also factor in. Get multiple quotes. Ask what's included: inspection, removal, sealing, and any follow-up visits. A low quote may not cover repairs, so compare apples to apples.

Renters, Landlords, and Who Pays for Squirrel Removal in DC

In DC, landlords are generally responsible for pest control in rental properties. That includes squirrels. If you're a tenant, report squirrel issues to your landlord promptly. They must provide a safe, habitable home. Landlords should have a pest control professional inspect and address the issue. Costs are usually the landlord's responsibility, but check your lease. Some leases require tenants to maintain cleanliness, which can prevent pests. If you're a landlord, act quickly. Squirrel damage can become extensive and costly. Document the issue and keep records of repairs. Hiring a licensed pro ensures compliance with DC regulations and protects your property.

Prevention Tips for DC Row Houses and Older Homes

DC's older row houses have unique features. Brick exteriors may have gaps around pipes or vents. Shared walls mean squirrels can enter one home and travel to another. Inspect your roofline and attic regularly. Trim tree branches that overhang your roof. squirrels can jump from branches to your home. Install metal flashing where rooflines meet walls. Use heavy wire mesh on vents and chimneys. Seal gaps around utility lines and cables. If you have an attic, keep it clean and free of food debris. Consider a chimney cap. These steps reduce entry points and make your home less inviting.

How to Compare Two Squirrel Control Quotes in DC

When you get quotes from two DC squirrel control companies, compare what's included. Look for a detailed inspection, removal method, sealing of entry points, and a warranty or guarantee. Ask how they handle litters and if they follow up. Check licensing and insurance. DC requires nuisance wildlife permits. A professional should be happy to provide proof. Ask for references or reviews. Price isn't everything. A cheaper quote may mean less thorough work. Look for a company that explains the process and answers your questions. A written estimate protects you. Compare the scope of work, not just the total cost.

When to Call a Professional

If you hear persistent noises, see active chewing, or find droppings, call a professional. They can identify entry points, remove squirrels legally, and seal gaps. DIY attempts often miss hidden openings or trap young, leading to bigger problems. If you're unsure about laws or need help with repairs, a licensed nuisance wildlife operator is your best bet.

DIY vs Professional

DIY squirrel control often fails because homeowners cannot locate all entry points or use inappropriate methods like poisons or traps that may kill non-target animals. Sealing an attic without ensuring all squirrels are out can trap animals inside, leading to death and odor. Professionals use one-way doors, inspect thoroughly, and provide service guarantees. While DIY may cost less upfront, professional exclusion typically saves money long-term by preventing repeat infestations and fire damage.

Local Context

In Washington, DC, the mix of historic architecture and abundant greenery creates unique squirrel control challenges. Row houses in neighborhoods like Capitol Hill, Georgetown, and Dupont Circle often have shared walls and complex rooflines, making it easy for squirrels to move between properties. The District's strict animal control laws require humane removal methods; trapping and relocation is permitted only by independent pest-control providers. Additionally, DC's tree protection regulations mean you may need a permit to trim certain trees, so consult with an arborist before cutting branches near your roof. For apartment buildings and multi-unit properties, squirrels can enter through damaged vents or gaps in the roof, affecting multiple units. Property managers should schedule annual inspections, especially before breeding seasons.

Prevention Tips

  • Trim tree branches to at least 10 feet away from your roof to eliminate jumping access.
  • Install chimney caps and heavy-gauge wire mesh over vents, soffits, and fascia gaps.
  • Seal any holes or cracks in the roofline, siding, or foundation with steel wool or metal flashing.
  • Secure garbage cans with tight lids and remove bird feeders if squirrels are a problem.
  • Inspect your attic regularly for signs of entry, especially after storms or during breeding seasons.
  • Ensure attic windows and vents are screened and in good repair.
  • Remove stacked firewood, debris, or overgrown vegetation near the house that provides shelter.

💡 Did You Know?

  • squirrels use a deceptive caching strategy: they dig fake holes and pretend to bury food to mislead thieves watching them.
  • squirrels can rotate their ankles 180 degrees, allowing them to climb down trees headfirst with ease.
  • a squirrel's front incisors grow about 6 inches per year, requiring constant gnawing to keep them short.

Frequently Asked Questions

What should I do if I hear scratching in my attic?
First, confirm it's not a bird or raccoon. If sounds occur during daylight, it's likely squirrels. Inspect your attic for droppings, nests, or entry points. Do not seal the entry hole without professional help, as you may trap animals inside. Call a licensed wildlife control operator to install one-way exclusion doors.
Can I use poison to kill squirrels?
No. Poison is inhumane, illegal for squirrels in many states, and poses risks to pets and children. Poisoned squirrels often die in walls, causing odor and attracting flies. Professional exclusion is the safe, legal, and effective method.
How much does professional squirrel removal cost in DC?
Typical costs range from $250 to $500 for removal alone, and $500 to $1,500 for full exclusion and repair. Factors include the number of entry points, roof complexity, and damage repair. Many companies, like Squirrel Removal, offer inspection terms that vary by provider.
Do I need to repair insulation after squirrel removal?
Yes. Squirrel urine and droppings can contaminate insulation, creating health risks and odors. After exclusion, replace contaminated insulation and disinfect the area. Some companies include basic cleanup in their service.
How can I prevent squirrels from coming back?
Seal all potential entry points with steel mesh, trim tree branches 10 feet from the roof, install chimney caps, and secure vents. Regular attic inspections help catch new gaps early. A professional exclusion with a warranty provides long-term peace of mind.
What time of year are squirrels most active in attics?
squirrels seek attics during two breeding seasons: late winter/spring (February–March) and late summer/fall (August–September). They also invade in autumn to find warm winter shelter. Peak activity varies with climate, but DC sees increased calls during these periods.
Is it legal to trap and relocate squirrels in DC?
In Washington, DC, live trapping and relocation require a license from the DC Department of Energy & Environment. Relocation must be to a suitable habitat, and it is illegal to release animals on public property without permission. Always use a licensed professional.
Will my homeowners insurance cover squirrel damage?
Many standard policies exclude damage from pests, including squirrels. However, if a squirrel gnaws a wire and causes a fire, the fire damage may be covered. Check your policy and consider adding a rider for pest damage. Prevention is cheaper than repair.
