Livin' WellSolar Sonic Pest Repeller Stakes - 4pk Outdoor Pest Repellent with 5,000 Feet Range, Solar Powered Animal Control, Rodent Repellent and Deterrent for Mole, Vole, Gopher

I have used these for years, we have 5 acres and the moles are destructive especially if they get in to your lawn area. I’ve tried smoke bombs not effective, I didn’t want to use traps to kill them.These ultra sonic moles and voles repellent work pretty well it has kept them out of the areas I don’t want them in. As long as you follow the directions and you get enough to cover the area you want them go they work well.I just bought 8 more as they moved into a section they had not been in before.

DON’T WASTE YOUR MONEY ON THIS WORTHLESS PRODUCT!! It doesn’t work and I’d rate it zero stars if I could. I put all four around the outside perimeter of our 2-car driveway with two directly on each side (one in a planter and one in the landscaping rock) of my husband’s Mazda that has show evidence of mice. He started the car this morning and saw a mouse scurry out and hide under a rock that we put a bag over to try to catch it. My homemade mouse trap works better and it cost me NOTHING. We also bought the under the hood electronic mouse devices and will report on those later...

These work great in the garden, it's amazing how well they keep critters away

Well, I've had one stake in my lawn for a week & it seems to have deterred the moles that dug up parts of my yard. I see no new holes and my yard is a good size. Out of the pack of eight, I only used one because of the sound it makes "every 30 seconds". Yes, 30 seconds because I timed it. Just to be on the safe side, I will add another stake about 20 yards away, hoping the noise can't be heard along with the one.

1 of them doesn't work. Been in the sun for 3 days now and still no sound like the others. Will update this review as to the effect they have on my ground hog issue in 2 weeks. Missing that one in the middle of the property line I hope will not effect the results in a negative way

Just purchased recently - Easy to install

Instructions are clear and fine. I didn't need them. I've been through maybe 5 different sets of these things. Various brands and models. I seem to always find them with my tractor.1st, this set has an on off switch that is a bottom facing push button. I found this annoying as id have to check the position over and over again. If you push this unit down and the ground presses the button, it turns itself off. Switches that slide are much better.Out of the box, 2 units flat out didn't work. So I had 6 "useable' ones. It's been 4 days since this install and about half of those 6 work. They all are muffled and the the length of time they keep is half a second at a time. I think 1, maybe 2 might be beeping as it should. But it's not loud.I installed my previous vole destroyers in the yard where the malfunctioning units from this order were installed. They still work like a champ. Even after the tractor for a couple.I would not recommend this brand of these. They are all cheap but some are cheaper then others. Go for a larger range instead of quantity. Also, use a wooden stand hammered into to the ground to make your hole for your vole destroyers shaft. Way better then a shovel!Happy hunting.

Some of the unit does not produce sound it just buzz.
