What Causes Squirrels in the Attic?
Squirrels are usually drawn to your attic in search of nesting space that is warmer, safer, and more comfortable than nesting space outdoors. They enter through roof vents, attic louvers, and ventilation fan openings but can also squeeze through small cracks and gaps in soffits, eaves, fascia boards, windows, or siding.
These factors can increase the likelihood of a squirrel infestation in your attic:
- Access: Tree branches near your roofline make it easier for squirrels to reach your roof. From there, unrepaired damage and unscreened openings create opportunities for squirrels to enter your attic.
- Food: Nearby food sources, such as bird feeders and tree nuts, can lure squirrels to your property.
- Seclusion: The lack of bright lights and regular human activity in the attic is attractive to squirrels that want to ensure their nests remain undisturbed.
DIY Squirrel Removal Methods
Before you begin to rid your attic of squirrels and seal entry points, inspect the attic for signs of baby squirrels. If you remove a squirrel but later see it frantically trying to reenter, you may have separated a mother from her young. In this case, allow the mother back inside to tend to her babies. Squirrels often nest with their young from February through May or August through October.
Exclusion Devices
Begin the process of ridding your attic of squirrels by identifying entry points and installing exclusion devices. Block all the entrances but one with metal flashing, wire mesh, steel wool, hardware cloth, caulk, or fiber cement, and cover the final entry point with a one-way door. This device allows squirrels to freely exit the attic but prevents reentry.
You should not install a one-way door if you encounter a squirrel nest with babies. If the mother squirrel is trapped outside, her baby squirrels will likely die, and the mother squirrel may damage your home’s exterior in a desperate attempt to reach her young.
Live-Capture Traps
Live traps are a humane option for removing adult gray squirrels and other critters without harming them. Bait traps with peanut butter, and check them daily. Once you have caught a squirrel, take the trap outside and carefully open the door with the trap facing away from you until the squirrel leaves.
Research wildlife laws and pest control regulations in your state before using squirrel traps, and make sure to release squirrels near your home instead of dropping them off in a new area. Squirrels are territorial, and the squirrels from your attic may be vulnerable to attack in a new location.
Squirrel Repellents
Natural squirrel repellents—such as apple cider vinegar, black pepper, garlic, and peppermint— can repel squirrels from your attic and discourage them from returning. Try soaking a rag in one of these ingredients and placing it near the nest or entry point.
You can also purchase a commercial squirrel repellent on Amazon or from your local hardware store or garden center to mimic the smell of predator urine and scare squirrels away from your attic. Spray the repellent near entry points or anywhere you’ve seen squirrel droppings.
Avoid mothballs, a repellant that will leave a persistent odor in your home and potentially kill squirrels.
Squirrel Deterrents
You can convince squirrels to leave your attic by making the area less hospitable. Try placing a few bright lights and motion-activated devices in your attic, which will make the area seem less safe. Bang pots and pans or leave a radio playing in the attic at full volume overnight to serve as additional deterrents. High-frequency sound machines may help, though reviews from scientists and users are mixed.
Professional Squirrel Removal Methods
Professional exterminators and pest control companies offer a variety of solutions for dealing with your squirrel problem and other issues involving insects or wild animals. Many companies offer special pest control pricing for ongoing services.
Exclusion and Prevention
Wildlife removal experts can seal potential squirrel entry points and install exclusion devices, such as one-way doors and chimney caps, to keep squirrels from invading your home. Professionals can recommend preventive measures catered to your property, such as trimming overhanging tree branches.
Trapping and Removal
Professionals routinely use humane live trapping to safely capture squirrels. The process involves placing live traps in your attic to catch the intruders, then relocating them to a suitable outdoor habitat. Look for a company that uses environmentally friendly techniques, is properly licensed in your state, and follows all local regulations.
Wildlife Repellents
Pest control companies may use wildlife repellents, which emit odors that repel squirrels, to expel the rodents from your garden or attic. A professional exterminator will have access to more products than homeowners will.
Tips for Squirrel Prevention
Follow these tips to prevent squirrel damage and infestations:
- Change food in your bird feeder: Load your bird feeders with seeds that squirrels find less appealing, such as safflower seeds or white proso millet.
- Coat birdseed in hot pepper: The capsaicin in hot peppers will deter squirrels without affecting birds.
- Inspect your attic regularly: Conduct routine inspections of your attic, roof, and home exterior for signs of squirrels or entry points.
- Maintain a tidy yard: Remove fallen fruits, nuts, and seeds from the ground to reduce food sources that attract squirrels.
- Reinforce weak points: Seal gaps, cracks, and holes in your roof, soffits, fascia boards, and eaves.
- Seal attic openings: Install sturdy screens over roof vents, attic louvers, and other openings that squirrels could exploit.
- Trim trees near your roofline: Keep tree branches at least 6 to 8 feet away from your roofline to prevent squirrels from using them to access your attic.
- Use lights and noise: Install a bright light, noise machine, or motion-activated device in the attic to scare squirrels away.
- Use squirrel-proof bird feeders: Position bird feeders away from your home and use squirrel-proof models.

How We Chose the Top Pest Control Companies
Our pest control research process starts with analyzing customer reviews on third-party websites such as the Better Business Bureau (BBB), Trustpilot, and Google Reviews. We then do a deep dive into each company’s website, service plans, and available cost information. We also secret shop the companies we review, reach out to representatives, and request quotes.
From there, we compile the information we’ve gathered and compare each company using our in-depth pest control methodology and review criteria. This process uses a series of factors that are important to our readers, and we score each company depending on how well they perform in each factor. For instance, companies that offer more guarantees for their service earned more points than others, and pest control plans with a larger range of covered pests earned more points than ones with fewer.
After analyzing dozens of residential and commercial pest control businesses through this process, we were able to determine the best pest control companies on the market.
