How It Works

How it Works

The Victor® PestChaser® is a highly effective method of controlling rats and mice.

Here is the way in which the Victor® Ultrasonic PestChaser® works to repel rodents:

Non-Repetitive Sound Waves- High frequency sound waves emit a non-repetitive pattern to repel rodents and prevent them from invading your home. With over 80 oscillations per second, this electronic mouse repellent sounds like a jackhammer to mice. This type of sonic pest control is safe for humans, cats, dogs, birds, and fish. Hamsters and guinea pigs will simply need to be moved to a room without an ultrasonic rodent repellent.

This type of control is a classic animal behavior modification technique. The complex sound waves emitted by the PestChaser® do not allow rodents to habituate to the sound. These Ultrasonic devices have the ability to provide long-term reductions in rodent populations by creating a "rodent-unfriendly" environment that discourages rodent infestations.

It is important to note that ultrasonic frequencies do not travel between walls. So for the most effective rodent control, ultrasonic devices need to be placed in multiple rooms. Additionally, since sound waves are absorbed into soft surfaces, units should not be placed behind couches, curtains, or other obstructions.

The most common repellent mistake is using the devices alone to control an established infestation. Traps and rodenticides as well as sanitation and exclusion effort should be used in conjunction with ultrasonic repellents. In fact, ultrasonics can be used as a herding tool to force rodents into areas equipped traps and baits.

The Victor® Ultrasonic PestChaser® is one of ONLY two ultrasonic device granted registration by the Canadian EPA(PMRA) due to their strict testing standards on electronic rodent repellent devices. Below is the lab data and field test results that allowed us to gain registration and become the leader in ultrasonic devices.

The purpose of this study was to test the theory that rodents will tolerate a change in their environment perceived to be temporary; but, when the condition persists those rodents will make a conscious effort to avoid the new adverse condition.

Lab Testing

Test Protocol

A mouse was placed in a test apparatus with 2 types of chambers - treated (ultrasonic device) and untreated (no device). Food and nesting areas were provided in the both chambers. Food consumption and tracking board activity was measured.


Food consumption was reduced by 67% in treated chambers.

Rodent tracking board activity decreased 21%.

Field Testing

Test Protocol

Seventeen consumers with existing rodent problems participated in the field test series. Test sites were required for each pest species - Norway Ray, Roof, Rat, & House Mouse. Testing phase lasted 6 weeks with daily monitoring of activity. Food consumption and tracking board activity was measured.

In addition to researchers, a licensed pest control company was responsible for supervising the project.

In total, PestChaser® successfully repelled the rodents from the protected area in 13 of the 17 sites. This represents a 81.3% success rate.

Sixteen sites demonstrated that rodent activity ceased in 3 to 9 days after devices were activated.

The average number of days before rodent activity was stopped was six days.

Expert Tips
Non-Toxic and Safe To Use Around Children &
Non-Rodent Pets
  • No chemicals or poisons
  • Sound is inaudible to humans and non-rodent pets
  • DO NOT use a PestChaser® around rodent pets such as gerbils,
    hamsters, guinea pigs, rabbits, etc.
