Vekibee 2 Piece Solar Powered Sonic Mole Repellent Rodent Repellent Ultrasonic Pest Repeller Outdoor Pest Control Repels Mole Rodent Vole Shrew Gopher

Bought four sets of these. They cleared out 20,000 square feet of yard overnight. I've had them going nearly a month and NO MORE MOLES! Now I just need to till the damage done and plant grass seed.

They have been in the ground for about 4 weeks now, i am not sure if they are helping yet, but I have not seen new mole hills. Will report back in a month or so.you can hear them when outside, but not in the house.

I see from other reviews that these don't work for everyone. I didn't want to go the trap/poison route so I thought I would try these out and I can say that they drove away my Florida moles in just a few days. Those moles had managed to dig a network of tunnels in my lawn that made it somewhat dangerous to walk around on and now they seem to be completely gone after a year long infestation. The moles are somewhere else now. I really didn't want to kill them, the moles are just doing what moles do. I just wanted them to leave my lawn, and they have.I have noticed that the two spikes do not operate at the same frequency. You can clearly hear the difference in tone. I don't know if that is intentional, or a manufacturing defect, but they still worked.

Hard to say if they are working or not, I think they are. I've purchased 4, but as others have reported, one has stopped working. I've contacted Amazon, and they are sending me a shipping label to return them. The other 3 appear to be working fine, and have survived a few cloudy days and have started up again. Since I am using these and mole repellant granules it is hard to say which is working. Activity has certainly decreased.

So, now we have 6 of these!! Love them.We have a pool that all the critters think is a pond. We surrounded the pool with 4, and they no longer play in the water, drink from it, nor hang out on the deck around it. The other two are near the garden and front porch where the ground squirrels and moles wreck havoc.My son is sensitive to sounds, these do not bother him as they are not extremely "painful" ~ you will hear them though but I have already blocked them out.

This device started working right out of the package. It will make very quiet buzzing noise (barely noticeable unless you are standing right beside it). It covers 30 meters in each direction, so 2 of these can very well cover the area around my house and my gardens. It has been about a week and I have not seen any rats lurking around like before.

Chipmunks made swiss cheese of our flower beds along the top of a 30' stone retaining wall in front of our home.I had to completely redo the flower beds last year because of the damage. Though I was successful with rat traps baited with peanut butter and sunflower seeds (bagged 26 chipmunks and mice at last count), others moved in and continued to to damage the plants and displace the soil around the stone wall.Ordered two of these units and again rebuilt the flower beds. Installed the two units and have not seen a single chipmunk since!!!Ordering two more units today!!!

My front yard was torn up by moles and looked like a messy road map. I try to keep a better looking yard and feel that this product can help. Applied 2 sets of the mole repellents in the yard very easily and didn't take much time. In 2 weeks my yard improved little by little. It didn't happen overnight. But stick with this product and it will save your yard.
