Devices emitting high frequency noise are often advertised as being able to repel pests via ultrasonic sound. They are, according to their manufacturers, specifically designed to repel, injure or even eradicate pests — such as insects and rodents — completely. However, it should be noted that both testing labs and the US Federal Trade Commission (otherwise known as the FTC) dispute these claims.
If pests in your home worry you, then undoubtedly you will value the importance of pest control. Who wouldn’t want to have a home that was pest free? Exactly. Some methods will deliver more effective results than other ones (which, for example, take more time). As the customer it is entirely up to you which approach you decide to take as determined by time, cost and method.
Electronic pest control is basically an approach that uses specially powered devices to eliminate or repel insects and rodents. Electronic pest control devices are not usually under the purview of any governmental agencies and so inspections and tests of electrically powered electronic pest control devices tend to be less stringent than those applied to other methods used. This has raised doubts among homeowners about the efficacy and safety of such devices. The technologies used in these devices are not new but are still evolving. The premise does require further studies and more in depth knowledge and scientific facts.
