Do Ultrasonic Electronic Pest Repellents Really Work?
Ultrasonic electronic pest and insect repellent devices claim that their high frequency sound waves are intolerable to rodents and insects. However, simply plugging in one of these devices probably won`t end your pest woes. It`s important to understand exactly what these devices can do before investing in one.
If you dig a little deeper into the various products, you`ll find that the studies have mixed results. Overall, some ultrasonic pest control devices show some results with certain pests – how`s that for convincing? These products are by no means a quick fix, and none of them claim 100% effectiveness on any pest, so they need to be kept in perspective as a possible contributor to an overall pest management system, not as a magic weapon.
If you`re thinking of adding electronic repellents to your pest-control system, keep in mind:
Keep Trapping: The best results for both rodents and insects come from using ultrasonic pest repellents along with trapping. Simply put, the sound waves cause the pests to scurry around, which drives them right into your traps.
Expect Diminishing Returns: Pests such as rodents become accustomed to the sound from ultrasonic devices over time, so results may only be temporary.
Have Realistic Expectations: Even the successful research on ultrasonic pest control devices shows a percentage of decrease, not a total elimination of rodent and insect pests.
Device Location: The sound waves from ultrasonic pest control devices are short range and very weak, so they`re easily blocked by furniture, walls, and corners.
