As a homeowner, keeping squirrels away is crucial because they can chew wires, wood, and insulation, invade attics or gardens, and spread disease through droppings or parasites. Preventing them protects your home and your family’s health and avoids costly repairs.
Getting rid of squirrels on your own can be a tough nut to crack. Yet many homeowners decide to take matters into their own hands and purchase readily available squirrel repellents to rid their houses of them. From chemical to natural remedies, here are some common types you’ll find in stores and online.
Types of Squirrel Repellents and Deterrents
Most squirrel repellents work by making your property smell bad, taste bad, or feel uncomfortable, encouraging squirrels to move on without causing harm. There are two main options for keeping squirrels away: chemical and natural repellents.
1. Repellent Sprays
Repellent sprays are one of the most popular choices because they are so easy to use. Natural sprays can contain capsaicin from chili peppers, peppermint, eucalyptus, garlic, and citrus oils. These are supposed to be smells that squirrels dislike. Sprayed on garden beds or bird feeders, they are meant to deter squirrels. These sprays have limited use as wind, rain, and time reduce their efficacy. In addition, squirrels are tenacious creatures and will tolerate these scents until they fade.
It’s important to note that there are no specific squirrel poisons available, as poisoning squirrels is illegal.
2. Ultrasonic Repellent Devices
Sound deterrents are devices or methods that use noise to scare or irritate squirrels and keep them away from your property. The most common are ultrasonic devices that emit high-frequency sounds humans can’t hear, along with motion-activated units that produce sudden noises or play predator sounds, such as barking dogs or hawks.
These types of repellents have been growing in popularity as, unlike chemicals, they are seen as harmless to both the squirrels and house residents. However, there is no scientific evidence that these devices work, and the Federal Trade Commission has been warning consumers against them.
3. Granular Repellents
Granular repellents are typically made from natural ingredients, such as dried blood, predator urine, or hot pepper flakes. These granules can be scattered around gardens or outdoor areas to create a barrier that squirrels will avoid.
These have strong odors that you would not want to use in your attic. Used outdoors, just like the spray deterrents, these will also fade away, requiring frequent applications. In addition, predator urine, such as fox urine, can attract fox predators like coyotes. And coyote urine can attract coyotes looking for a mate.
4. Motion-Activated Sprinklers
Motion-activated sprinklers are another recommended natural deterrent for squirrels. When activated, they are supposed to startle and scare squirrels away. They might work on squirrels scampering outside, but most squirrels that nest in attics are tree squirrels that hop onto your roof from tree branches. These squirrels will not be affected by the sprinklers at all.
In addition, the placement of the sprinklers is key. They need to spray the path the squirrels take to approach your home or garden bed. And squirrels can learn how to avoid the spray.
5. Natural Repellents
Natural repellents typically rely on strong smells like peppermint, garlic, or cinnamon. These are a safer option for homes with pets or children, but they usually require more frequent reapplication and may be less effective against heavy infestations.

Do Squirrel Repellents and Deterrents Actually Work?
Squirrel deterrents can help, but they have limitations and drawbacks. Examples include:
Inconsistent Effectiveness
One of the biggest issues is the inconsistency in effectiveness. Squirrels are persistent and smart, and they can become used to certain smells, tastes, or sounds over time.
Maintenance
Another common problem is frequent maintenance. Many repellents, especially sprays and natural solutions, need to be reapplied often, like after rain, snow, or even regular watering.
Safety Concerns
There are also safety concerns with some products. Studies show pesticides, including those containing strong irritants or compounds such as polybutenes, can cause long-term health risks if misused around pets, children, or edible plants. Products like mothballs are particularly problematic because they contain toxic chemicals and are not intended for open-air use.
Limited Coverage
Some deterrents also have limited coverage. For example, granules may only protect the exact area where they’re spread, and ultrasonic devices may not work through walls or around obstacles, leaving surrounding areas open for squirrel activity.
Doesn’t Treat the Root of the Problem
Deterrents don’t address the root problem. If squirrels have already found a way into your attic or are nesting on your property, repellents alone usually won’t remove them. In those cases, you need professional help to fully resolve the issue.
What to Do Instead
Instead of relying only on repellents and deterrents, the most effective approach is to remove what attracts squirrels and physically keep them out. The process should begin with a thorough inspection to learn more about squirrel activity on your property, like how and why they are present. Then, you must develop a plan of action that not only gets rid of squirrels but keeps them away in the future. This is where calling a professional wildlife removal service is recommended.
A professional, such as those at Critter Control, can safely locate entry points, remove squirrels and their nests, check for hidden damage, and ensure no animals are left behind, especially during nesting season when babies may be present. They also use proper exclusion techniques, like one-way doors, to prevent squirrels from re-entering without trapping them inside your home.
Working with Critter Control experts not only resolves the current issue but also helps prevent future infestations.
