Technically, the behavior of pest species like cockroaches or rodents can be influenced or impacted by certain ultrasonic sounds, especially when administered in a laboratory in a very specific way. When turned on, the devices actually increased the rate of mosquito bites by 50 percent. A study recorded in the Journal of Vector Ecology investigated the impact that ultrasonic pest repellers had on mosquitoes. They might even have the unintended effect of doing exactly the opposite and making pest problems worse. ![]() Sometimes, ultrasonic devices don't just fail to chase away pests. For instance, a study of rodent repellent devices for the United States Department of Agriculture and the National Wildlife Research Center found that rodents stopped responding to the ultrasonic sounds after just a few days of exposure. Similarly, a 2015 study conducted by the University of Arizona concluded that, although the number of patents for ultrasonic pest repellents had increased over the years, commercially available ultrasonic pest devices were not an effective means of treating pest problems.Īnd even when they do work, the effects are short-lived. However, in the end, there was no statistical difference when compared to not using an ultrasonic pest repeller. Do ultrasonic pest repellers really work?ĭespite manufacturers claiming ultrasonic machines affect all these different species, well-constructed research supporting these claims is scant.įor instance, a study on how ultrasonic pest repellers affect bed bugs found that bed bug activity did seem to change slightly when the devices were running. The claim is the same: Unwanted animals and insects find the noise impossible to withstand and vacate the premises.īefore investing in these devices, homeowners should investigate the research that explores the efficacy of ultrasonic pest repellers. Rather than put up with the annoying noises from the device, the pests may flee your home and garden and seek refuge in areas not blanketed by the high-frequency sounds.Ī related group of pest control machines, known as "subsonic pest repellers," work in a similar fashion and use very low-frequency sounds or vibrations. The manufacturers behind ultrasonic pest control devices claim that a wide range of pest species don't like the sounds and vibrations emitted by the machines. ![]() The claim behind ultrasonic pest repellers Fleas and ticks (you can even find pet collars with battery-operated ultrasonic devices embedded in them).Most ultrasonic pest repellers claim to drive away a variety of unwanted home and garden visitors, including: What kind of pests do ultrasonic pest repellers work on? When turned on, the machine emits high-pitched sounds or high-frequency vibrations, which are typically imperceptible to human ears, although some individuals with more sensitive hearing may hear them. However, some devices are battery-operated for easier use in fields, gardens, sheds and other areas that aren't wired for power. The devices typically get plugged into an electrical outlet. Ultrasonic pest control solutions market themselves as easier and safer than more hands-on pest repellents and pest control options. What is an ultrasonic pest repeller?Īn ultrasonic pest repeller is an electronic pest control device that emits a high-pitched sound at a frequency that may cause discomfort to, kill, drive away or incapacitate household pests. The Federal Trade Commission has been warning consumers about ultrasonic pest control devices for decades, as manufacturers do not have the scientific evidence required to back up their claims of effectiveness.īefore you invest in an often-pricey ultrasonic pest control device, make sure you understand the distinct pros and cons of electronic "plug pest control." Let's dive deeper into more information around ultrasonic pest repellers before we offer up some ways to approach pest management in a non-aggressive way. And ultrasonic pest devices and plugins make a big, bold promise: effortless pest removal with the push of a button.īut these promises are largely empty. ![]() Many homeowners often turn to DIY pest repellents in order to save money. In many cases, DIY pest control has some risks and downsides-and you may just wind up spending more in the end in an attempt to control a pest problem on your own.
