I have mice getting in my garage. I think they are squeezing in between the door rubber insulation and concrete. I have the door closed as tight as possible and sealed around the frame. Mice can however fit through a hole the size of a dime. I’ve been trapping the little bastards but I’ve been looking into something that will make my garage not appealing. I'm trying moth balls now. I’ve read about ultrasonic rodent repellers and some people swear by them while some claim they don’t work.
I was looking at some ultrasonic transducers at Newark and found a couple the
MCPCT-G5800-4143 for example seems to be the most powerful from the limited information I can find. Could anyone who used something similar answer a couple of questions?
How can you determine the maximum range?
Is the max range achievable through a wide frequency range 40-50kHz?
Do you need to supply the max voltage to get the most power out? In the case of the multi-comp one its 90V.
Does anyone know of a transducer that would be effective over 40-50kHz range and give a meter or so range.
Whats a typical drive circuit? Hbridge?
Has anyone tried ultra sonic emitters for rodent deterrent and does it work?
I’ve been trying to find a brief summary of these things and haven’t had any luck. If anyone who’s used these can point me to one it would be appreciated.
