Eradware Solar Powered Mole Repellent (2 Pack), Ultrasonic Pest Repeller, Vole Rodent Repellant, Also Repels Away Snake Gopher Chipmunk, Use in Outdoor Garden Lawn, Non-Toxic Eco-Friendly and Humane

I just installed tgese 2 days ago so it is a little early to be rating them.They turn right on and start vibrating. I used a similar product last year that was effective and tgese appear similar for a much bettee price. I use to deter voles from flower bulbs and other veggies

Used a small auger to drill a hole to put them in the ground - didn't want to pound on them.I hear them buzzing and haven't seen any mole or gopher mounds near them. I'll update if anything changes.

I received the mole repellers on time and they look like a good quality item. Haven't had the chance to see if they repell squirrels which is why I got them but I have learned that they don't seem to bother my dogs.

Put these in the ground this spring, and my moles all appear to be gone. Highly recommend.

I liked the product, real easy to put into the ground.

Units are working fine. They seem to be of good quality and emit a loud sound. The installation instructions were weak or non-exsistent and didn't agree with the information given on line. I installed them 4 inches above ground. Hopefully that is deep enough to be effective. We already had 3 sonic mole repellers ( mow over variety ) buried in the ground. One of them needed batteries. I purchased the Eradware mole repellers because because of 7 new holes dug into our back yard. I'm not sure whether these were mole holes. We did have moles in the past. We have had a problem with squirrels digging for grubs and doing a lot of damage to the yard. I'm spraying Bayer Advanced complete insect control to control the grubs. I'm hoping that the combining effects of the mole repellers and the insect spray will take care of our mole and squirrel problems. At this point it's too early to tell. Not sure if I'll use the Eradware devices year round. Hopefully the Eradware devices are as effective as the battery models buried 11 inches into the ground. If you have any suggestions for me I would appreciate it.

I ordered 4 of these ultrasonic repellers and they worked from February 2019 to April 2019. (Maybe longer). I then headed north for the summer and when I returned in November, they had stopped working. When I pulled them out of the ground I realized they were full of water. I was able to open two of them and dried them out. I couldn’t open the other two as the screws had become too rusted. Odd that an outdoor device doesn’t have stainless screws. The two that I dried out were too far gone and I had to throw them out too. I ordered Toro devices so I hope to get better results.

I recorded a 2mn video where the device is active under a bright sunshine. I can hear the sound when I'm close enough to the device. And the squirrel is having some good time next to it digging his hole.I'm planning to return it in 2 weeks if the symptom persist. Seller can email me to request the video.
