Mole Repellent Solar Powered 4 Pack Ultrasonic Sonic Repellent, Vole Snake Gopher Deterrent Spikes for Lawn Garden, Outdoor Yard Groundhog Chipmunk Repeller

These mole stakes work really well. We had a mole tearing up our yard. I tried mole killer and the little devil would just push it out of its runs, lol.Got these hoping they'd help just a little. The moles were gone within the first week and haven't been back since. Definitely will purchase these again if needed.

Totally ineffective. They pushed up another mound all around this as if to show me how much it didn't work. Was place according to instructions. This is one week after installation. Still sounding and not effective at all.

It does it job, however, it is not working on scaring the animals away.

They may work, but I thought they were silent. They're not. They sound like a lamb going "bahhh!!" every 30 seconds. I kept a couple going but had to turn them off near my bedroom. They don't seem to work at distances because I definitely have gophers in the spots I turned them off.

I didn't actually expect these to work well, but I thought I'd give them a try anyway. And surprisingly the voles are gone from my lawn! Now, my poor neighbor's lawn is in rough shape. But he can buy some too if he wants and send the voles down the street to the next neighbor. haha

I bout 4 boxes of these thinking I’d get rid of unwanted varmints. They have been in the ground since the day I bought them. Oct3 and it is Oct 20. Today, I notice two huge mounds of dirt right next to them. They are noisy and I can hear them going off all day while I’m in my house. I figured that’s okay, as long as the gophers are moving to a different neighborhood. Unfortunately, they are still camping out in my yard. Worthless for the $120plus that I spent on them!!

I discovered an issue with moles in my front and back yards at the end of the summer. I placed two of these in my front yard and the mole activity did stop.I am now placing the other two in my backyard as the experiment seemed to work.

These may be alright for rodents but it doesn't do anything to snakes, I had a 4' 3" chicken snake getting in my pigeon loft eating babies and eggs so I bought this to repel the snakes. After I had these installed that night the snake got 3 more babies and I found the snake laying in rocks about 2 feet from the device and it didn't act like it was a bit shook up by the device and I managed to get rid of the snake on my own.
