It is variable frequencies. Inaudible to humans and non-rodent household pets, the ultrasonic sound is broadcast in intermittent volume levels up to 100 dBA and varying frequencies (20 kHz to 65 kHz) to disorient and perturb pests. The Pest Reject is simple to use and safe around family and most pets.

Yes it is up to you, but we recommend you to install one for each room because the ultrasound cannot penetrate walls and solid objects.Please make sure there are no barriers like curtains or cabinets covering in front of the repellent.

The Pest Reject is completely harmless to all animals.  Some cats or dogs may be leery of the unit(s) for the first few days, but most will be used to it without any problems.

Ants, rats, roaches, rats, mice, centipedes, and more.

Although some customers have reported success with these pests, results have varied with snakes, spiders, bees, mosquitoes, silverfish, flies, and other flying insects.

The Pest Reject repels insects and rodents, but does not kill them. This is beneficial because you don't have to deal with removing any dead pests from the inside rooms or walls of your home. The pests are humanely and safely repelled back outside.

The Pest Reject is designed for indoor use. The ultrasonic sound waves emitted from Pest Reject will utilize the inside walls of your home to bounce around and fill the room with pest-repelling sound. The height at which the Pest Reject is plugged in does not really matter, as long as the Pest Reject is plugged into an open area. For best results do not plug the Pest Reject in behind any large furniture that will block its speakers, such as couches, bookshelves, stoves, refrigerators, etc. Many types of pests are attracted to areas with food smells and water, so a common recommendation would be to place Pest Reject in your kitchen and bathroom. Always place a unit in the room(s) with the worst pest problem.

The Pest Reject is designed to be perfectly safe to use around people of all ages, including small children and babies.

Although the Pest Reject is safe to use around most house pets, we recommend closely monitoring your pet's behavior for the first 48 hours while using the device.

Cats/Dogs: while rare, it is possible that some cats and dogs may hear the sounds that are produced. Each pet and situation is different, so our Money-Back Guarantee will give you time to use the Pest Reject  around your pets and ensure it doesn't bother them.

Birds: birds vary so much in size, breed and behavior. We have no way to guarantee the Pest Reject will or will not bother your bird. To be safe, we recommend not using it in the same room as your bird, or near the birds cage. Some customers have reported their birds seem bothered by the ultrasound; other customers tell us their birds seem just fine.

Fish: fish will not be affected by the Pest Reject. 

Reptiles: reptiles have much lower hearing ranges than mammals (i.e. people, dogs, cats, and rodents), so they will not be affected by the device. This also means that it cannot be used to repel reptile pests.

Rodent pets: rodent pets include rabbits, guinea pigs, chinchillas, ferrets, hamsters, mice, gerbils, rats, degus, prairie dogs, and sugar gliders. Since the Pest Reject uses ultrasonic sound designed to repel rodents, your rodent pets will be bothered by this unit. But, since ultrasound does not go through walls, rodent pets can be kept safely in a bedroom (or another room) behind a closed door. Your pet will also be safe if the device is used on the other side of the home, or on a different floor of your home, or if the pet is outdoors and the device used is indoors.

As we are not medical doctors, we cannot guarantee that the Pest Reject will be completely safe around medical devices. Although no one has reported problems to date, we strongly recommend consulting your physician before using any type of electronic around a medical device such as a hearing aid, pacemaker, defibrillator, etc.

Although the Pest Reject uses ultrasound technology inside the walls of your home, the high-pitched ultrasonic sound that fills the inside of the room will not go through walls. This is why we recommend at least two to three units per floor for best results. Units can be placed in different areas of your home, depending on your building's floor plan and where the pests are a problem. By using multiple, strategically-placed units throughout your home or office, you effectively distribute the ultrasonic pest repelling sound throughout the structure. This optimizes your overall electronic pest control. Although the electromagnetic feature will travel throughout your home wiring with the use of one unit, it has been our experience that using more than one unit simultaneously presents the greatest results. One unit is better than no units, but multiple units will yield more powerful results than one unit alone.

Although many customers report results within a few days, we recommend you give the Pest Reject 2–4 weeks to completely eradicate your pests. Results can vary depending on the type of pests, location, and degree of infestation.

Note: be aware that under some situations of extreme drought or other adverse conditions, the pressure on any creature becomes so great that survival overrules any deterrent.

The sounds emitted from the Pest Reject are above the normal human hearing range, although some people can hear a very faint beeping sound (virtually undetectable). The device sends out negative ions to trick pests sense of smell to think a storm is approaching (similar to the smell before a rain storm). However, these smells are undetectable to humans. The Pest Reject will have no noticeable odors.
