Mefru Indoor Ultrasonic Pest Repeller - Electronic Repellent for Insect, Rodent - Mouse, Rat, Ant, Spider, Fly, Cockroach, Bed Bug, Flea, Mosquito - Humane, Poison-Free Plug-In Deterrent - Night Light

Seems to be working- I put few in my kitchen where there had been some mouses activity. It said that we have to give it a time to work. And it really worked! Haven’t seen any mice in our house. Highly recommended for everyone!!! LOVE IT

I’m loving this product and it works really well. It helps me get rid of those little bugs that fly around in my room. I’m definitely buying more to put in my other rooms. It’s really easy to use and all I had to do was plug it in. Would recommend to friends and family. THANK YOU MEFRU

I live in farm where has many rats and bugs. Just bought it 2 months ago. I have to say thank to Mefru, it is awesome product which I was looking for a while. Now I sleep without cricket‘s sound. 👍

I had a problem with mice, rats & squirrels in room. I tried everything to get rid of them, but nothing worked I plugged one of these ultrasonic repellers into a wall receptacle, and the problem ended!

We have used this type of product for ants for several years but the one we used to use is no longer manufactured. We tried several other brands and they couldn't touch the million ants that like to be in our mudroom. Within hours - literally hours - of plugging this in, there has not been an ant in sight. Simply Amazing!

I have issue with lizards on my porch and roaches in my house.. This is helping me in controlling them and definitely worth a try.

Just like the instructions said, at first we saw a few sweet ants on our kitchen countertop but have seen none for several weeks now.

6/7 I'm updating just to say it didn't work. Customer service was good at addressing the issue with rhe beeping unit. However the replacement was the exact same. It does stop beeping after playing around with it. But they're have have been 2 plugged up for weeks now and I have ONLY NOTICED AN INCREASE IN BUGS.... this is not the fault of the device..I see this every time summer starts to roll around. The plug in changed nothing..This is an update to the first review.. I gave 3 stars because of customer service.. they reached out and sent me a new device at no cost and ensured that the sound could be turned off. However it was the same exact device and yes the sound can be turned off,but that is something you must figure out how to do on your own.. again, I say it's not mentioned in the description and it s not on the in the box instructions. Now that I have figured out how to turn off sound, I'll wait to see if I notice a difference.... thumbs up for customer service but I'm not convinced about the device. The advertising says this is a soundless device. Nowhere in the instructions does it mention that annoying beeping.. I had to search through questions and answers to get any info on.I will update if I notice any difference in the amount of spiders I usually get during the warmer months.. but definitely won't be 5... the product is not as advertised..
