Ultrasonic Pest Repeller - Electronic mouse, insect repellent, Pest Control with NO Chemicals, Poisons, Traps. Controls Rats, Mice, Bed Bugs, Ants, Spiders, Mosquitoes, with Night Light [2 Pack]

Bought these and there was absolutely no improvement in mouse activity for about 2.5 - 3 weeks. To be fair, this is EXACTLY what the product instructions suggest. So, stupidly, I gave up and purchased some traps. Now, the first night I had the traps (x6) down I caught one mouse... and have subsequently had ZERO mouse activity. Can't knock the trap - it worked perfectly; but I'd really not wanted to kill the mice and would much prefer discourage them from entering our living space. I can't believe that on the back of one mouse fatality the local mouse community communicated a warning to all mice not to enter the property because of the newly installed traps. So, I think the ultrasonic repeller had started to effect the mice, just as the supporting information suggests. The traps have been down for 6 nights now ... no more dead mice, no more mouse poops anywhere. Wish I'd saved myself the money on the traps ... I'll be putting them away.

Do not buy this product! Was bought due to my son being bitten constantly by mosquitoes at night! I have followed the instructions to the letter and last night he has been bitten 5 times after the machine being plugged in for 5 weeks! We have still got spiders (babies and huge ones!) and constant flys! And now I’ve missed the return deadline by 10 days! a waste of money!

Ultrasonic Pest Repeller recently purchased. A really good buy. Seems to be working.

Hard to know how good these are as only just received them, however the product I received is different from the one pictured/ordered. It is missing the MEER sign and although very similar looking, appears like a non-branded version. Hopefully it'll still work, but I suspect it's cheaper/reduced for a reason.

We got these for a mouse problem in our house as well as clouds of mosquitos. Happy to report the mice are gone and the mosquitos drastically reduced. One thing to bear in mind, these things don't kill the creatures, they just move them on. Any pest control man will tell you they are rubbish so be aware. They may move out of your house and into your garage or even into another room out of earshot of the unit. Great if you don't like killing things just because they're sharing your space with you. Recommended solution - in some situations, luckily ours was one of them.

To be honest I am not sure if it works or not, most of the people I speak to say they don't. I still saw little mice in the garden very near the kitchen where I had this thing switched on, so query its effectiveness. Similarly, it does not stop any bugs getting in, and I still get mice sounds under the floor boards. Would I buy this again, or recommend it to anyone, probably not, may be useless waste of money.

I’ve been warned these ultrasonic pest repeller wasn’t effective but I had to try it and now I can tell you it is completely useless. I’ve plugged the two items really close to the bin where the mice is use to come and I noticed the same activity for the 2 following weeks. Result: useless

I have been using this for a week now and as recommended by the seller I have left it switched on and will continue to do so . It really does seem to be working my home backs onto fields and as the weather has been so cold field mice have moved into my kitchen . I used it in conjunction with traps for the first few days and it certainly did upset the mice . Over the 2 days I've had no sign of any mice .....so fingers crossed they have moved out ! I'm interested to see how it works with insects in the warmer weather as that will really be a bonus Delivery time from order was excellent and communication from the seller was really helpful ........ highly recommended
