Below is a guide to the top 6 best squirrel repellents on the market, as well as a quick guide on how to use them properly. Best Squirrel Repellent

Although cute to look at, Squirrels can be damaging pests. Squirrels can chew holes in doors and wires, damage the insulation and leave their feces inside your home.

They can damage your garden by chewing up bark, building nests and gnawing on plants. Squirrels can carry diseases that can spread through their feces affecting the health of your family and pets.

Let’s get Started!

​What Types of Squirrels Repellents Exist? 

​Basically, there are two major types of squirrel repellents – the ultrasonic and the chemical type. Now let’s move further down to their details.​​​

Ultrasonic repellents – Ultrasonic waves have a frequency above 20,000 hertz which is undetectable by the human ear. Most animals like squirrels, dogs, and mice can hear ultrasonic sounds.

It works by emitting non-repetitive pitches of ultrasonic sound that will frighten and bring discomfort to the rodent. This behavior-modification technique works by simply creating an unfriendly environment and not by harming or killing them. In general, 60Hz is a good frequency to look for.

Chemical repellents – Chemical squirrel repellents are usually blends of natural ingredients that can be repulsive to rodents. The most common ingredients are vinegar, peppermint, garlic, hot peppers, etc.

Such sprays simply force the pest to leave rather than hurting them physically. We would recommend that you choose natural ingredient sprays rather than the heavy-duty industrial ones that can be less humane.

Fear Inducement Devices – Devices that resemble the prey of squirrels are used to scare them away. Features like flashing LED lights and loud sounds are often added to such repellers.

Now that you know the different methods of treatment, there’s still the question of choosing the best squirrel repellent for your needs. Keep the below factors in minds before purchasing a product:

  • How large is the area that is squirrel infested- if 1-2 squirrels are bothering you, the spray will do the job easily
  • How much reapplication are you willing to do
  • Are there children or pets in the house? If so, choose a product with natural ingredients that will not affect their health
  • If you have many pests besides squirrels, you can choose an ultrasonic repeller with adjustable frequency to target them all
