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!
Tried 3 different ultrasonic models last summer - zero effect on my squirrel problem. The little guys just ignored them completely. @PestControlPro any professional opinion on why these fail?
@UrbanGardener Most units don’t emit frequencies high enough to bother squirrels consistently. They’re more effective on mice. For squirrels, I recommend physical barriers combined with taste repellents on plants.
Made my own ‘ultrasonic’ test - played squirrel distress calls through outdoor speakers. Worked for 2 weeks until they figured out it was fake. These critters are too smart!
Important safety note: Some ultrasonic devices actually distress dogs and cats in the neighborhood. Always check frequency ranges before buying!
After wasting $200 on various repellers, I installed metal flashing around my attic vents. Problem solved permanently. Ultrasonic = expensive placebo in my experience.
Newer ‘variable frequency’ models show promise.
