How Do Ultrasonic Pest Control Devices Work?

By : Rita Stadler

house mice rummaging through food stuffs If you’ve noticed rodent activity like droppings, gnaw marks or nests around your home, it’s time to start looking for a way to remove these pests from your space. 

One of the more recent developments in the pest control industry is the ultrasonic mouse repeller. These devices work by sending ultrasonic sound waves through the air that are meant to send mice running. The advantage of this method is that it doesn’t require using any harsh chemicals within your home. However, the question often comes up, do they really work?

How These Devices Work

Typically, the repellent device is plugged into an electrical outlet anywhere homeowners have noticed a pest infestation. The electricity generates ultrasonic waves that are beamed into the area and when a rodent travels into the path of the waves, they can feel them and hear them. The manufacturers claim that the electromagnetic technology creates a high-frequency sound that is unpleasant to pests, and the discomfort causes them to leave the area. However, the sounds are supposed to be out of range for human hearing. 

Potential Problems with Ultrasonic Pest Repellers 

Scientific evidence for ultrasonic devices is mixed. Additionally, reviews for these types of products often suggest the repellers do not always solve mouse and other pest problems. Many consumers actually find ultrasonic rodent repellents to be completely ineffective.

Homeowners will likely need to place several units throughout multiple rooms around the house since the sound waves from these devices cannot go through walls or furniture. In order to keep the waves moving, placing several in the same area is the recommendation; however, this can get expensive.

Along with the high costs, there are other possible issues with electronic rodent repellers: 

  • Finding a place to put the device can be a problem: Any object in front of the repeller will prevent ultrasonic waves from reaching rodents. 
  • You may have the perfect spot to plug in the ultrasonic repeller, but if that isn’t where the rodents are traveling, the repeller will be completely ineffective. It may be difficult to determine how many of the ultrasonic repellers you need for your area.  
  • It could get difficult to know when the product needs to be replaced since the sound is inaudible. And, even though it’s inaudible to you, it could be causing discomfort for your pets.
  • If your pest problem is an enclosed area without electricity, like a shed, you won’t be able to use an ultrasonic repeller to get rid of the rodents.

Is There a Better Way? A pouch of Fresh Cab Rodent Repellent inside someone's home.

Fresh Cab® is a great alternative for ridding any area of mice and rodents. You can use Fresh Cab pouches anywhere indoors, as well as in enclosed areas like sheds, barns, and garages. Simply place the pouches in areas you have seen rodents and in areas where they might be entering into your home, such as behind appliances and under sinks. Rodents like to follow pipes into structures and can squeeze through the tiny holes where pipes and wires are.

Fresh Cab® rodent repellent is a botanical product made from corn cob chips, herbal extracts, and plants. The smell produced from these ingredients is pleasant to humans, but offensive to rodents. The pests smell the balsam fir scent and leave the area. EarthKind’s rodent repellent is registered by the EPA for use indoors and is a USDA Certified Biobased Product.

For mouse prone areas use 1 pouch per 125 sq. feet placed at the entrance for protection. Replace when the scent is no longer strong to the nose. For areas with known rodent infestations, use one pouch per 8 sq. feet of floor space for up to 30 days of maximum protection.
