Ultrasonic Pest Control Devices

Do they work?


Ultrasonic pest control involves the use of devices that emit ultra-high frequency sound waves that are meant to chase away rodents, bats, birds, and other pests.  Some ultra sonic pest control devices claim to work for cockroaches, fleas, silverfish, and spiders.  There are even card-sized devices that you can carry in your pocket to repel mosquitoes, and tiny devices designed to be worn around the necks of cats and dogs as flea collars.  Some run on batteries (like the pocket cards and flea collars), but most are designed to be plugged into an electrical outlet.

The sound waves these ultrasonic pest control devices emit are too high a frequency to be heard by humans or most pets (if you have pet mice or other rodents, they will be able to hear them and may be disturbed by them, obviously, but they shouldn’t bother your cat or dog).


Buying Ultrasonic Pest Control Devices

You can buy ultra sonic pest control devices at many hardware and home improvement stores, or you can buy them online.  The price of the devices really varies.  You can find devices for around $10 or you can pay several hundred dollars for a device.  It depends on the quality of the device, the pests it is meant to repel, and its range. 

But Do Ultrasonic Pest Control Devices Really Work?

Ultra sonic pest control devices sound so easy.  Just plug them in and no more pests, right?  Unfortunately, research has not shown that they work.  In fact, in the 1980’s, the Federal Trade Commission (FTC) charged a number of companies that make ultra sonic pest control devices with false advertising and required them to make refunds to a number of customers.

One problem is that most devices have a fairly limited range, anywhere from 15 – 30 feet.  So you would need multiple devices in your house.  Objects placed between the device and the place where the rodents are likely to be create a “shadow,” which offers the rodents protection from the sound.  Since mice tend to hide under the furniture and inside the walls, a device placed on a table or shelf in the room may have little effect on them.

Even when directly subjected to the sound, however, it just doesn’t seem to bother most pests very much.  In studies, such devices were places right next to cages of rodents, for example.  The rodents, while they could supposedly hear the device, went on to live what seemed to be normal lives.  When males and females were placed in a cage together, they bred.

Alternatives to Ultrasonic Pest Control Devices

There are a number of alternatives to ultra sonic pest control devices.  For instance, you can buy mousetraps or bug sprays at hardware stores and most grocery stores.  However, depending on the severity of your pest problem and the type of pest you’re dealing with, do-it-yourself treatment measures may or may not be effective.

We recommend you schedule an inspection by a pest control professional to identify the type of pest you’re dealing with and to advice you on the best course of action.  Many pest control companies actually offer a free inspection, so it costs you nothing to get a professional opinion.
