Audio repellents are often called “ultrasonic electronic pest repellent devices” and they claim that by using high-frequency soundwaves, the noise becomes intolerable to rodents, raccoons, skunks, and other critters and pests. The problem is that it isn’t as simple as this. The age-old expression “if it sounds too good to be true it probably is” is true in this case. How easy would it be to just plug in one of these ultrasound emitters and have all your pest problems solved? If it really worked then every home in America would have one.

When looking at a 2001 Federal Trade Commission finding, they sent a warning to the manufacturers of these ultrasonic pest control devices, demanding that claims of effectiveness must be backed up by scientific research. These once seemingly magical devices have come under more scientific scrutiny which has shown not only how they work, but how effective they might be.

If you are adamant that you want an ultrasonic pest repellent, then our advice is not to expect any miracle or to use it as a sole repellent. These high-frequency sound emitters could be effective when used in conjunction with other types of repellents.
