Do sonic gopher repellents work?

I’ve heard of castor oil-based repellents; any feedback?

Castor oil worked better for me than sonic devices.

I’ve used a sonic repeller in my yard, gophers left for a bit, but they crept back after a month. Maybe they got used to the noise?

Installed one near my garden, worked like a charm for two weeks, then new mounds popped up. Anyone else see short-term success?

My solar-powered sonic stakes kept gophers away all summer, vibrations at 400 Hz seemed to do the trick. Worth a shot!

Tried a sonic device, gophers didn’t budge. I think my soil’s too dense for the sound to travel far enough.

I’ve had one running for a year, gopher activity dropped, but I paired it with castor oil granules. Combo might be key!

Set up a sonic repeller near my flower beds, mounds stopped for a while, but I’m skeptical it’s a permanent fix.

Mine buzzes at random intervals, gophers hate it, and I’ve had peace for months. Placement near tunnels seems critical!

I’ve read they work better in small yards, tried it on my acre lot, and the gophers just moved to the other side.

Sonic stakes chased gophers off my lawn initially, then they returned. Maybe they adapt, or my unit’s too weak?

Used one last spring, no new gopher holes since! But I’m wondering if it’s the sound or just luck with fewer gophers around.
