How It Works

The unit emits high-frequency sound intended to make the surrounding area less comfortable for certain pests. Ultrasonic sound does not travel effectively through walls and may be weakened by furniture, curtains, carpets, and other soft materials.

Results can vary according to room layout, infestation severity, placement, pest species, and environmental conditions. This product should be used as one component of a broader pest-management approach and is not presented as a guaranteed extermination method.

Three-Level Frequency Control

The device is confirmed to have three adjustable frequency levels. Consult the included instructions to select the appropriate level for the intended pest.

Some settings within the stated 9–36 kHz range may be audible to people or animals. Reduce the setting or discontinue use if the sound causes discomfort.

Installation and Use

1. Read the included instructions before operation.

2. Plug the unit directly into a compatible indoor wall outlet.

3. Select the frequency level recommended for the intended pest.

4. Confirm that the blue operating light is illuminated.

5. Keep the front of the device unobstructed.

6. For flying insects, the supplied guidance recommends positioning the unit approximately 30 inches above the floor.

7. Allow time for pest activity to change and continue ordinary sanitation and exclusion measures.

8. Use additional units for separate rooms because ultrasonic sound does not pass effectively through walls.

Do not install the device behind furniture, curtains, appliances, or other objects that could block its output.

Product Specifications

Placement Recommendations

For the best opportunity for coverage:

• Install the unit in an open, unobstructed location.

• Use it only in dry indoor areas.

• Place it in the same room where pest activity has been observed.

• Do not expect one device to cover multiple enclosed rooms.

• Avoid positioning it behind soft furnishings that may absorb sound.

• Combine it with cleaning, food storage, sealing entry points, and removal of nesting materials.

The stated 80–120 m² coverage is a manufacturer or packaging claim and may be reduced substantially by walls, room divisions, furniture, and other obstructions.

Important Safety Information

• Indoor use only.

• Keep the device dry and do not use it near water, excessive moisture, or wet surfaces.

• Do not handle, install, or unplug the unit with wet hands.

• Do not cover the device or block ventilation openings.

• Keep away from heat sources, open flames, and direct exposure to liquids.

• Do not use a cracked, damaged, overheating, or unusually noisy unit.

• Keep children from handling the device or inserting objects into it.

• Plug the unit only into a compatible, properly installed outlet.

• Discontinue use if people or animals experience discomfort.

Although the packaging identifies the product as child- and pet-safe when used as directed, ultrasonic devices may be audible or disturbing to animals with sensitive hearing. Use particular caution around pet rodents—including hamsters, gerbils, guinea pigs, mice, and rats—and consult a veterinarian before operating the device near them. Keep birds, reptiles, and other sensitive animals under observation.

Do not use this product as the sole control method for a serious infestation or a situation that may affect health or property. Contact a licensed pest-control professional when appropriate.

Frequently Asked Questions

How many repellers are included?

This Listing is for one repeller, one instruction manual, and one retail box.

Is it intended for outdoor use?

No. The confirmed application is indoor use only.

What area can it cover?

The stated unobstructed coverage is 80–120 square meters, or approximately 861–1,292 square feet. Actual coverage varies, and walls can prevent the signal from reaching adjacent rooms.

Does it have adjustable settings?

Yes. The device has three adjustable frequency levels. Follow the included instructions when selecting a setting.

Which pests is it intended to discourage?

The packaging identifies rodents, mosquitoes, and other common household pests. Effectiveness can differ by species and environment.

Does it kill pests?

No chemical pesticide or trapping mechanism is identified. The unit is intended to discourage pests through ultrasonic output, not directly kill them.

Is it safe around pets?

The packaging identifies it as pet-safe when properly used, but ultrasonic frequencies may affect animals with sensitive hearing. Do not operate it near pet rodents without veterinary guidance.

Can one unit cover an entire house?

Not necessarily. Ultrasonic sound generally does not pass through walls, so separate enclosed rooms may require separate units.

How will I know it is operating?

The blue indicator light should illuminate after the device is plugged in. Consult the manual if the light does not appear.

Are results guaranteed?

No. Results depend on pest species, placement, room layout, competing food sources, entry points, and infestation severity. Use sanitation and physical exclusion measures alongside the device.
