Tried it in my yard, squirrels didn’t care at 25 kHz. Might need a stronger unit or something they can’t ignore.
My solar repeller at 35 kHz worked, squirrels stopped chewing my wires. Been quiet for two months now!
Used one near my garden, squirrels scattered at first, but they’re back. Wonder if they adapt or if coverage is spotty?
I’ve had mixed luck, 40 kHz chased squirrels from my shed, but they still romp in the trees nearby.
Plugged in a 50 kHz unit, squirrels vacated my roof fast! Still watching to see if it’s a long-term win.
My repeller buzzed at 28 kHz, squirrels didn’t flinch. Maybe it’s not loud enough, or they’re just too stubborn!
