Hi all, I was just re-reading the Wikipedia pages for rattus exulans, rattus norvegicus, and rattus rattus, as you do, and one of those pages talked about rats being sensitive to ultrasound, with baby rats and mating females making ultrasonic calls.
So naturally I wondered if there had been any research into using ultrasonic lures for rats, or trials of them.
Does anyone have experience, or know of research into ultrasonic lures?
