​What Types of Squirrels Repellents Exist? 

Ultrasonic repellents – Ultrasonic waves have a frequency above 20,000 hertz, 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 the right 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 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.
