The most reliable way to get rid of squirrels is physical exclusion: sealing every entry point so they can’t get back in. Repellents, traps, and deterrents all play supporting roles, but none of them work long-term if squirrels still have easy access to your attic, garden, or bird feeders. Your approach depends on whether squirrels are inside your home, raiding your yard, or both.
Getting Squirrels Out of Your Attic
If squirrels are living in your attic, the goal is to let them leave on their own and then make sure they can’t return. A one-way exclusion door, mounted over the main entry point, lets squirrels push out but blocks them from coming back in. This only works if every other gap, crack, and vent opening is sealed first. Miss even one, and they’ll find it within hours.
For sealing materials, half-inch hardware cloth is the standard for keeping squirrels out of vents and openings. Quarter-inch mesh stops mice and bats but is less flexible and can clog with dust or reduce airflow on intake vents. Galvanized sheet metal, screwed into framing, resists prying by squirrels and raccoons alike. Stainless steel or vinyl-coated hardware cloth is stronger and rust-proof if you want something more permanent. Foam, caulk, and plastic vent covers won’t hold up. Squirrels chew through them quickly.
Soffit vents are a common weak point. Covers should be mechanically fastened to framing or blocking every 12 inches so squirrels and wind can’t pop them loose. Roof-soffit intersections, gable vents, and gaps where utility lines enter are the other spots to check carefully.
Timing Matters More Than You Think
Gray and fox squirrels breed twice a year. The first litter arrives in late January through February, and a second round comes in late summer or early fall. Gestation takes about 42 to 45 days, and the young don’t leave the nest until they’re 10 to 12 weeks old. If you seal up your attic while babies are still inside, you’ll end up with dead animals in your walls and a desperate mother tearing new holes to reach them.
The safest windows for exclusion work are late spring (after the first litter has left the nest) and late fall (after the second litter is mobile). If you’re unsure whether juveniles are present, listen for high-pitched chirping or scratching sounds that are more frantic and frequent than the typical adult scurrying. When in doubt, call a wildlife control operator before sealing anything.
Keeping Squirrels Off Bird Feeders
Squirrels can jump about 4 feet vertically from the ground and leap 8 to 10 feet horizontally from a tree, fence, or roofline. That dictates everything about feeder placement. Your pole needs to be at least 8 to 10 feet from the nearest surface a squirrel could launch from, including tree branches, deck railings, and the side of your house.
A cylindrical baffle mounted on the pole blocks squirrels from climbing up from below. Position the bottom of the baffle about 44 inches off the ground so the top sits around 58 to 59 inches high, which is above their vertical jump range. If the pole is too close to a tree or structure, no baffle in the world will help because squirrels will simply bypass it with a horizontal leap.
Scent and Noise Repellents
Peppermint oil, hot pepper sprays, and predator urine (fox or coyote) are commonly recommended as squirrel deterrents. They can provide a short-term nudge, particularly in enclosed spaces like attics or crawlspaces where the scent concentrates. The catch is that they need to be reapplied every few days, and any rainfall washes them away entirely. Outdoors, they fade fast and persistent squirrels simply learn to tolerate them.
Ultrasonic repellent devices are a popular purchase but a poor investment. These plug-in units claim to drive away rodents with high-frequency sound, but researchers at McGill University found that commercially available devices have never been proven to work. Some animals habituate to the noise quickly, and others aren’t bothered in the first place. Lab-grade ultrasound generators can disrupt certain animal behaviors, but consumer products can’t replicate those complicated sound patterns. Save your money.
Repellents work best as a short-term complement to physical exclusion, not as a standalone solution. Spraying peppermint oil around a freshly sealed entry point may discourage a squirrel from testing the repair. Relying on scent alone to keep squirrels out of an open attic will not work.
Live Trapping and Relocation
Live traps baited with peanut butter, sunflower seeds, or whole peanuts will catch squirrels reliably. The harder part is what comes next. Squirrels have a homing range of roughly 2 to 5 miles, and some individuals navigate back from as far as 10 miles. Releasing a squirrel a mile or two away is essentially giving it a short detour. People who’ve tracked their results often report that even 8 miles, with a river crossing in between, wasn’t enough to prevent a return within two weeks. Releases of 10 to 15 miles near forested habitat tend to be more effective at preventing return trips.
Before you set a trap, check your state and local wildlife laws. Relocating squirrels is illegal in several states, including California and Washington, because it spreads disease and causes severe stress to the animal. Fines can reach $1,000. Even where it’s legal, trapping creates a vacancy that neighboring squirrels fill within days if you haven’t sealed the entry points that attracted the first one. Trapping without exclusion is an endless cycle.
Making Your Yard Less Appealing
Squirrels stay where food and shelter are easy to access. A few changes to your yard can reduce the incentive for them to stick around:
- Trim branches back at least 8 to 10 feet from your roofline, gutters, and any structure you want to protect. This eliminates their main highway onto your roof.
- Clean up fallen fruit, nuts, and birdseed regularly. Ground-level food sources are the primary draw for squirrels exploring a new yard.
- Use enclosed feeders with weight-sensitive perches that close under a squirrel’s weight, or switch to safflower seed, which most squirrels dislike.
- Secure trash cans with bungee cords or locking lids, the same way you would for raccoons.
None of these steps will eliminate squirrels entirely. They live in trees across most of North America, and your yard will always be part of someone’s territory. The goal is reducing the concentration of food and access points so squirrels pass through instead of moving in.
When to Hire a Professional
Professional wildlife removal typically runs $299 and up for a straightforward squirrel-in-the-attic job that involves trapping, a few repair patches, and follow-up visits. More complex situations, like multiple entry points, damaged insulation, or chewed electrical wiring, start around $599 and go higher depending on the scope of attic restoration needed. A single-trip removal of one animal can cost as little as $99, though that rarely solves the underlying problem.
Costs increase for homes that are far from the service area, require rooftop work with safety equipment, or involve health hazards like accumulated droppings. If you’re hearing squirrels in your attic during breeding season and suspect babies are present, a professional can inspect the space and time the exclusion work properly. The price of a service call is significantly less than the cost of removing dead animals from your walls and repairing the damage a panicked mother squirrel inflicts trying to get back to her litter.
