Squirrels may look cute, but when they invade your attic, they can become a major nuisance. They chew on wires, insulation, and wood, causing costly damage. They also leave behind droppings and create noise, especially during early morning and evening hours.
One of the most effective ways to remove squirrels from your attic is by using noise deterrents. Loud or high-frequency sounds can make the attic uncomfortable, encouraging them to leave on their own. This guide explores the best noises to scare away squirrels, other effective removal methods, and prevention tips to keep them from returning.
Why Do Squirrels Invade Attics?
Squirrels seek out attics for three main reasons:
- Shelter: They look for warm, dry spaces, especially during colder months.
- Nesting: Female squirrels often build nests in attics to raise their young.
- Food Storage: Attics provide a safe place to store acorns and other food sources.
Understanding why they enter your attic can help you choose the best noise-based squirrel deterrent to drive them out.
What Noises Will Get Squirrels Out of the Attic?
Squirrels are sensitive to loud, sudden, and high-frequency sounds. Using sound as a deterrent can disrupt their sense of security and make them leave. Here are some of the best noise options:
1. Ultrasonic Sound Devices
Ultrasonic squirrel repellers emit high-frequency sounds that irritate and scare squirrels away but are inaudible to humans.
How to Use Ultrasonic Devices:
- Place the device near the squirrels’ entry points or nesting areas.
- Keep it turned on continuously for a few days to make the attic uncomfortable.
- Use a device with variable frequencies to prevent squirrels from adapting.
2. Loud Music or Talk Radio
Squirrels prefer quiet environments, so loud music or human voices can drive them out.
How to Use Music or Radio to Repel Squirrels:
- Set up a portable speaker or radio in the attic.
- Play rock music, talk shows, or sports broadcasts at a moderate volume.
- Leave it running for several hours each day, especially during active times (morning and evening).
3. Predator Sounds
Squirrels have natural predators, such as owls, hawks, and coyotes. Playing recordings of predator calls can scare them away.
Best Predator Sounds to Use:
- Owl hoots
- Hawk screeches
- Coyote howls
- Snake hissing
How to Use Predator Sounds Effectively:
- Play the sounds intermittently to make them seem real.
- Combine them with flashing lights or movement, such as fake owl decoys.
4. Banging Pots and Pans
Squirrels are startled by sudden loud noises, making banging pots and pans an effective way to scare them off.
How to Do It:
- Go into the attic and bang metal objects together.
- Repeat the process several times a day for a few days.
- Combine it with other deterrents, like bright lights and strong scents.
5. Leaf Blower or Air Horn
A leaf blower or air horn can create a loud and disruptive noise that forces squirrels to leave quickly.
How to Use a Leaf Blower or Air Horn:
- Direct the airflow or sound toward their nesting areas.
- Use it multiple times a day to make the attic an unpleasant space.
- Be cautious if there are baby squirrels, as they may not leave on their own.
Other Effective Ways to Get Squirrels Out of the Attic
Using noise is effective, but combining it with other methods increases your chances of success.
6. Use Bright Lights
Squirrels prefer dark, secluded spaces, so installing bright lights in the attic can drive them out.
How to Use Lights as a Squirrel Deterrent:
- Set up motion-activated LED lights.
- Keep the attic well-lit at night to disturb their nesting habits.
- Combine lights with noise deterrents for better results.
7. Apply Strong Scents
Certain smells repel squirrels and can be used alongside noise deterrents.
Best Smells to Use:
- Peppermint oil
- Ammonia-soaked rags
- Apple cider vinegar
- Predator urine (fox or coyote)
Place these scents near entry points and nesting areas to encourage squirrels to leave.
8. Set Up One-Way Exclusion Doors
Once squirrels are disturbed by noise, a one-way door allows them to exit but prevents re-entry.
How to Install an Exclusion Door:
- Identify the main entry hole.
- Attach a one-way squirrel door over the opening.
- Seal up other potential entry points with metal mesh or hardware cloth.
This method works best if there are no baby squirrels inside, as they cannot leave on their own.
9. Contact a Wildlife Removal Professional
If noise and DIY methods don’t work, it may be best to call a wildlife removal expert. They can safely and legally remove squirrels without harming them.
How to Prevent Squirrels from Coming Back
Once you’ve successfully removed the squirrels, it’s important to prevent future infestations.
10. Seal Entry Points
Squirrels can fit through small gaps, so sealing all potential entry points is crucial.
Common Entry Points to Check:
- Roof vents and chimneys
- Gaps in soffits or fascia boards
- Cracks in siding or roofing
- Openings around pipes and wires
Use steel mesh, hardware cloth, or metal flashing to cover these areas.
11. Trim Tree Branches
Squirrels use tree branches as access points to your roof.
How to Keep Squirrels Away:
- Trim branches at least 6–8 feet away from the roof.
- Remove vines or trellises that squirrels can climb.
12. Keep Food Sources Away
Squirrels are attracted to food sources near your home.
Tips to Remove Attractants:
- Keep garbage bins tightly sealed.
- Avoid feeding birds with uncovered bird feeders.
- Store pet food indoors.
13. Use Squirrel Repellents
Commercial squirrel repellents can add an extra layer of protection.
Best Squirrel Repellent Options:
- Peppermint oil sprays
- Hot pepper spray (made with cayenne or chili)
- Commercial granules designed for rodent deterrence
Apply repellents around entry points, attic spaces, and outdoor areas where squirrels are active.
Getting squirrels out of your attic requires a combination of noise deterrents, light, scents, and physical barriers. Ultrasonic devices, loud music, predator sounds, and banging noises can make your attic uncomfortable, forcing them to leave.
However, simply getting rid of squirrels isn’t enough. Preventative measures, such as sealing entry points, trimming trees, and using repellents, are essential to keep them from returning.
By following these effective squirrel removal techniques, you can enjoy a squirrel-free attic and protect your home from future infestations.
