Quick answer: To remove squirrels from an attic safely, identify their entry points, install a one-way exclusion door, and seal all other gaps once the animals have left. Avoid trapping during spring and summer, when baby squirrels may be nesting inside, since separating mothers from litters creates orphaned animals and lingering odor problems.
Few sounds are more unsettling than scratching and scurrying overhead at 6 a.m. Squirrels are agile, persistent, and surprisingly destructive once they’ve decided your attic makes a fine substitute for a tree hollow. Left alone, they chew through wiring, insulation, and wood framing, creating fire hazards and costly repairs.
The good news: getting squirrels out of an attic doesn’t require harming them. With the right timing, tools, and sequence of steps, homeowners can resolve an infestation humanely and prevent it from happening again.
How do you know if squirrels are in your attic?
Squirrels are most active at dawn and dusk, so scratching, rolling, or thumping noises during those hours are a strong indicator. Other signs include:
- Chewed entry holes around roof eaves, soffits, or vents (usually 2–4 inches wide)
- Droppings that resemble large rice grains, found near entry points or in insulation
- Visible nesting material, such as leaves, shredded insulation, or fabric
- Grease marks or dark smudges around access points from repeated contact with fur
Squirrels differ from rats in sound and pattern. Rats are more active at night and tend to move in quick, light scurries, while squirrels create heavier, more deliberate movement, often paired with jumping.
Why timing matters before removing squirrels from an attic
Squirrels typically give birth twice a year: once in early spring (February–April) and again in late summer (August–September). If a nest contains babies, sealing entry points or trapping the mother prematurely can trap or orphan the litter, leading to distress calls, odor from decomposition, and additional pest problems.
Choose removal methods if young are present if the litter isn’t visible or confirmed nesting age. Wait until babies are mobile (usually 6–8 weeks) if a nest is confirmed, since this allows the entire family to exit together through an exclusion device.
What’s the safest way to get squirrels out of an attic?
The most effective and humane method combines exclusion devices with entry point sealing. Here’s the general sequence:
Step 1: Locate all entry and exit points
Inspect the roofline, soffits, gable vents, and any gaps where the roof meets the wall. Squirrels often use overhanging tree branches or power lines to access the roof, so trimming branches within 6–8 feet of the house can reduce future access.
Step 2: Install a one-way exclusion door
A one-way exclusion door (sometimes called a squirrel funnel or excluder) allows squirrels to leave the attic but not re-enter. These devices are placed directly over the main entry hole and left in place for at least 5–7 days to ensure all occupants, including any mobile young, have exited.
Step 3: Confirm the attic is empty
Before sealing anything permanently, check for continued activity. Signs the attic is clear include no new noises for several days, no fresh droppings, and no returning activity around the exclusion device.
Step 4: Seal all entry points permanently
Once confirmed empty, seal the excluded hole and any other potential access points using heavy-gauge hardware cloth, metal flashing, or professional-grade sealant. Squirrels can chew through wood, plastic, and soft foam, so materials matter.
Step 5: Clean and repair the attic space
Squirrel nesting material and droppings can harbor parasites and bacteria. Removing contaminated insulation and sanitizing the area reduces odor and prevents attracting future pests through lingering scent trails.

Choose a one-way exclusion door if there’s a confirmed active nest and the goal is a humane, DIY-friendly solution. Choose professional removal if the entry points are difficult to access, the infestation is recurring, or local regulations restrict trapping and relocation.
What NOT to do when removing squirrels from an attic
- Don’t seal entry points before confirming the attic is empty. Trapping animals inside leads to death, odor, and secondary pest issues.
- Don’t use poison. Poisoned squirrels often die inside walls or attics, creating a difficult-to-locate odor problem, and poison poses risks to pets and other wildlife.
- Don’t rely solely on repellents. Scent-based deterrents may reduce comfort but rarely evict an established nest.
- Don’t handle squirrels directly. Squirrels can bite, scratch, and carry parasites; direct contact increases injury and disease risk.
How to prevent squirrels from returning to your attic
Prevention is simpler and cheaper than repeated removal. Effective long-term measures include:
- Trimming tree branches and vines away from the roofline
- Installing chimney caps and vent covers made of durable metal mesh
- Repairing fascia boards, soffits, and roof gaps promptly
- Inspecting the attic seasonally, particularly before spring and late summer birthing periods
Homes near dense tree cover or older properties with wood fascia are especially prone to repeat activity, so seasonal inspections are worth the extra effort.
Taking action before the problem grows
A squirrel infestation rarely resolves itself. Left unaddressed, chewed wiring and damaged insulation can turn a manageable nuisance into an expensive repair project. Acting early with a humane exclusion approach protects both the animals and the home.
For infestations involving hard-to-reach entry points, suspected litters, or repeated activity despite DIY efforts, contacting a licensed wildlife removal professional ensures the job is done safely, legally, and thoroughly.
Frequently Asked Questions
How much does professional squirrel removal cost?
Professional squirrel removal typically ranges from $200 to $600, depending on the extent of the infestation, the number of entry points, and whether attic repair or insulation replacement is needed.
How long does it take to get squirrels out of an attic?
Using a one-way exclusion door, the process usually takes 5–7 days to ensure all squirrels, including mobile young, have exited before sealing entry points.
Is it illegal to trap and relocate squirrels?
Regulations vary by state and municipality. Some areas require squirrels to be released on the same property where they were trapped, while others restrict relocation entirely. Check local wildlife regulations before trapping.
Can squirrels in the attic cause a fire hazard?
Yes. Squirrels frequently chew on electrical wiring to keep their teeth trimmed, which can expose live wires and increase the risk of an electrical fire.
What smells keep squirrels out of an attic?
Peppermint oil, ammonia-soaked rags, and predator urine are commonly used repellents, though they work best for prevention rather than resolving an active infestation.
