KN-18 Double Ultrasonic Mouse, Rat, Rodent, Squirrel Repeller

variable sounds but the sound button doesn't work

My wife and I recently had a lot of car issues suddenly pop up, it turns out that a large number of rodents have been building nests in EVERYONE'S cars on our block. They chewed through wires coming out of my wife's engine. I bought a subsonic little speaker/strobe unit to put in our car engine compartments. But with just 1 in each car, the rats were back the next night, and we found debris and rat droppings back on our engines. I installed a 2nd unit on the opposite side of our car engine compartments. Then also got THIS speaker unit. I have it hooked up under the wooden eave of our car port, pointing down at the nearby shrubs, and have power running up to it from an extension cord. It's blaring away 24/7 at those bushes. This unit, combined with the now 2 subsonic little strobe units we have in our car engine compartments, have made it to where we have gone for 5 straight days now without any sign of rodents whatsoever. No droppings, debris in the engine compartments, and not one single sign whatsoever of any rodent nests under the hood. On its own, I don't know if this would have done the job or not... but used in conjunction with the little units that go into your car's engine compartment, ,and this thing blaring downward onto the cars, we haven't had any issues since.

I live in MN in front of a marsh. We are new here. I feed many many birds as it is a new experience for me having so much nature. I did not think with this would come other critters!I have tons of squirrels on my deck that are now damaging it by chewing it! I figured I’d just have to fix it next year.Yesterday I saw a MOUSE in my kitchen! We have four cats!?! I bought this machine being proactive. I found very very little traces of said mouse. In fact it’s truly my fault because of the bird seed. I have been careless.I cleaned everything up and set this up last night. No trace of the mouse! I will be using it every night as well as buying traps. I also put all food away and put in tubs.What has just impressed me is this..... I have made a fool out of myself trying to rid these squirrels off my deck. Strobe lights, I’ve yelled at them... I’ve even sat and waited and used a leaf blower to scare them!?!I have RED SQUIRRELS AND GREYS! They appear to have been body building?! They are aggressive and have not a fear of anything not even a Bald Eagle in a tree! Well, I just set up this little gem outside and ya know what?!? NOT ONE SQIRREL ON MY DECK!!!!!!!!!!! I’m doing a dance in my living room!!!! I WILL be buying more as I had a Mother red squirrel about to give birth in my attic when we moved in , this past spring, that I thankfully was able to have trapped!Buy this product! Give it a chance! If you have a big problem you may need to double up on your “ammo” but I am so so pleased!OH DID NOT upset my 4 cats or my many many birds I feed. From Blue Jays to Chickadees.

Not sure if it’s working as yet let you know in another month

I bought 2 7ok-pest repeller Pest Control Device to get rid of the rats and bedbugs in my house. There are a lot of rats in my cellar, they come to my kitchen stealthily and leave some droppings in the cabinet. I bought this product and setup them at the cellar and the first floor.Previously the house is invaded by the bedbugs. I am not sure whether the product will be effective for the bedbugs. But it surprised me. After using the product, I cannot find the trace or droppings of the rats any more. We have a very old house built in the 1900's with the existence of the spiders and rats. By installing one of these products on every floor including the basement, our insect and mice issues have pretty much been eliminated. I will seriously recommend this to my friends. They can solve all the problems caused by the insects and rodents, because they are really effective. In fact, my parents asked me about this and they placed the order on the Amazon. They use it to deal with the rats. Now we all use the products and living happily.

Doesn't work

I was really skeptical about using high frequency sound to repel mice and insects. But after using this device for just a week, I'm astounded. Not only did I get rid of the one mouse we had in the house, brought indoors in a box from a relative's house, but it's also cleared our home of flies, mosquitoes, and moths in just 4 days. We live on a farm in a log house and are plagued by flies every summer. But I noticed after just 4 days of having this device plug in, in our living room, that the flies, mosquitoes, and other crawlies have vacated the house. Great side effect when I was just looking to keep the mice out.I bought two repellers this one and this one: https://www.amazon.com/gp/product/B06XT8F18Y/ Both were equally effective. I thought this one was more aesthetically pleasing for use where people will see it.Note, if you are a beekeeper, you don't want this within 4,000 feet of your bees.

My neighbors next door has rats problems.I saw them buying rat traps for sometime.Then finally they have a pest control co. to come get rid of the rats.Then my problems begin.I discovered lots of rat droppings behind my backyard door. I ordered this based on Amazon reviews as usual.Wow, the droppings are getting less and less each day. I am very happy with it.Then one morning I discovered 1/3 of the rubber of the door sweep of my garage back door has been chewed up and so was part of the door mat. Some rats are doing this to me ...? I quickly took the 7ok from my backyard to my garage near the back door, and ordered another 7ok for my backyard with no delay. Wow, whatever animals that are chewing my door sweep are gone as no more signs are seen.The backyard ? No more droppings are found since I got the second 7ok.HIGHLY RECOMMENDED!
