How to use sound to repel wasps

Electronic insect repellents are small ultrasonic devices that emit high frequency sound waves, the purpose of which is to repel or scare away insects. Some insect species--such as wasps, spiders, beetles and bees--sense ultrasonic vibrations, produce or perceive sound in ultrasonic frequencies and are affected by high-frequency sounds. The use of sound to repel wasps has not been scientifically proven, though products exist that claim to do just that. According to the Biocontrol Network, "it would take years and millions of dollars to test the effects of any electronic pest control device" on even one household pest group such as wasps.

Insert batteries or, if operated by electricity, plug the repellent's adaptor into an electrical socket.

Protect the pest-repelling device from moisture and extreme temperatures, especially if using it outdoors where wasps tend to gather. Look for devices that are manufactured for outdoor use, that are heavy duty and that have all-weather construction, so they can be safely used both indoors and outdoors.

Place the device, either free-standing or suspended, in the optimal location to repel the wasps.

Follow the specific machine's instructions for setting and adjusting the sound volume and sound frequency to the appropriate levels for repelling wasps.

Turn on the device.
