>Ultrasonic pest repellers are not an effective option for preventing or eradicating pests. Sometimes, ultrasonic devices don’t just fail to chase away pests. They might even have the unintended effect of doing exactly the opposite and making pest problems worse. A study recorded in the Journal of Vector Ecology investigated the impact that ultrasonic pest repellers had on mosquitoes. When turned on, the devices actually increased the rate of mosquito bites by 50 percent.
Ainuke juhus, kus ultraheliseade putukatele mõju avaldas katsetes… ja seal oli mõju vastupidine.

Need ultraheli masinad putukatele on kõik skämm.
Need ju aktiveerivad 5G välja su ümber, mis on putukatele surmav!
Võibolla mõni inimesele tundmatu puugiliik kuuleb ultraheli ja on sellepärast peidus.
