Drive Mice & Rats Safely Away

Keep rodents out before they enter your home, with advanced ultrasonic pest control technology from Victor®. Repellents use high-frequency sound waves to drive rodents away from your home. The Victor® PestChaser® is the only repellent backed by more than 20 years of laboratory research and proven field results.

How it works

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

There are two ways in which the Victor® Ultrasonic PestChaser® works to repel rodents:

1. 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, PestChasers® use an intense sound to create auditory stress for rodents. This type of control is a classic animal behaviour modification technique. The complex sound waves emitted by the PestChasers® do not allow rodents to become accustomed 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.

2. Mimics Sound From Alpha Male Rodent: For additional effectiveness, a distinct spike in sound (at 46.5kHz) replicates the sound of a dominant male rodent. Rodents are very territorial and will constantly fight to establish dominance. The sound of a dominant rodent will discourage others from inhabiting a territory.

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 efforts 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.

Lab & Field Test Data

Victor® PestChasers® are the only repellents backed by third-party laboratory research and exhaustive field tests. Additionally, the Victor® Ultrasonic PestChaser® is one of only two ultrasonic device granted registration by the Canada’s Pest Management Regulatory Agency due to their strict testing standards on electronic rodent repellent devices. Below are 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.

Results
  • 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. The 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.

Results
  • 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.

The results, as detailed above, present a clear picture of the efficacy of this particular ultrasonic rodent repelling device.

In the mid-1980s the Federal Trade Commission (FTC) in the US contacted all manufacturers of electronic pest control products (about 15 at the time) and required that each provide data for claims being made. In addition to repelling rodents, the fraudulent companies claimed to be able to repel insects and wild animals.

Most of the 15 companies simply rapidly left the business. Four companies entered into Consent Decrees that allowed no claims on packaging, and this put them out of business.

The Victor® Ultrasonic PestChaser® prevailed and received the stamp of compliance. The claims today are the same ones that were made when we first started selling ultrasonic devices. No hype is required: the PestChaser® does exactly as it was invented to do - repels rodents and keeps them out of your home.

Expert Tips

1. Location, Location, Location

First, identify a room that has signs of rodent activity. Rodents are nocturnal creatures, which mean they rarely surface during the daytime. Look for the signs of an infestation: chewing or gnaw marks, droppings, tracks and nests. Next, plug the unit into an outlet which is open to the rest of the room, not behind furniture where the sound waves may be blocked. Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. In a room with mostly hard surfaces, like a kitchen, ultrasound will “bounce” around giving more effective coverage. The ideal placement would be one that allows the sound waves to cross in front of an entrance way.

2. Use Multiple Units

Ultrasonic waves behave more like light than sound. For example, music from your stereo can fill your entire house. Ultrasound cannot penetrate any solid surface (walls, floors, ceilings) or travel around corners. This is why you need a unit for each room. The rule regarding square footage coverage is simple: an ultrasonic device can only cover the room in which it is installed; in a 3m x 3m room it covers 9 square metres, whereas in a double car garage it may covers 36 square metres. With obstructions, you will need to install more than one unit for maximum effectiveness.

3. Monitor Rodent Activity

Monitoring the signs of rodent activity will allow you to correctly place the units in high-frequency areas and allow you to direct the unit towards their entry points. Additionally, regularly checking for the signs of recent rodent activity (fresh droppings, rodent noises, new gnaw damage) will allow you to confirm the population is dissipating. Remember, rodent populations can tolerate unfriendly changes in their environment for only a short time, so you can expect to see a reduction in activity after 6 to 10 days on average.

4. Use In Conjunction With Other Controls For Established Populations

Ultrasonic devices should not be used alone to control an established infestation. Traps and rodenticides as well as sanitation and exclusion efforts should be used in conjunction with ultrasonic repellents. In fact, ultrasonics can be used as a herding tool to force rodents into areas equipped with traps and baits.

Frequently Asked Questions - Repellents


Answers to Frequently Asked Questions

Q: How does Ultrasound work?

A: Ultrasound is a frequency of sound too high to be heard by humans. Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. The Victor® PestChaser® sweeps a frequency of 32-62 kHz. Rodents find this sound irritating and will avoid it if possible. The non-repetitive frequency levels cause additional discomfort and do not allow the rodent to become habituated to the sound.

For additional effectiveness, the loudest spike in sound replicates the sound of a dominant male rodent. Rodents are very territorial and will constantly fight to establish dominance. The sound of a dominant rodent will discourage other from inhabiting a territory.

It is important to note that ultrasonic frequencies do not travel between walls. So for the most effective rodent control, ultrasonic units need to be placed in multiple rooms.

Q: How does Ultrasound affect rodents?

A: Ultrasound can repel rodents by subjecting them to intense auditory stress. This method is a classic animal behaviour modification technique.

Unlike traps and poisons, ultrasound does not kill rodents. The PestChaser® has the ability to provide long-term reductions in rodent populations by creating a "rodent-unfriendly" environment that discourages rodent infestations.

Q: What are the most common mistakes people made with repellents?

A: Ultrasound Alone to Control Infestation: The most common repellent mistake is using ultrasound units alone to control an established infestation. Simply plugging in a PestChaser® will not send rodents running for the door and out into cold winter temperatures if there is still sufficient food & shelter in your home or shed. It is important to also incorporate sanitation and exclusion techniques. Additionally, traps and baits should be used in conjunction to Ultrasonic devices.

Not Enough Units are Used: Ultrasound does not travel through walls so it is important to place 1 in each room.

Poor Placement: Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. Placement behind a couch will not allow waves to bounces around freely and cause a hostile sound environment.

Q: Is Ultrasound safe for pets?

A: The PestChaser® sweeps a frequency of 32-62 kHz, well above the range of hearing for humans and non-rodent pets like cats, dogs, birds, and fish. If you have a rodent pet such as a hamster or guinea pig, move them to a room without a PestChaser® unit.
