Pest Control Ultrasonic Repellent, Pack of 4 Ultrasonic Pest Repeller with Night Light - Electronic Plug In Mouse Repellent for Insect, Rats, Roaches, Spiders, Mosquitoes, Bugs ,Ant, Fleas

I ve been using since last Thursday so been 4 days. NO BUGS AT ALL. Highly recommend.

Works well and good to have one for other rooms.

Clean and simple and it works. I was skeptical as I read that ultrasonic devices need to wait for 3-4 weeks to have full effect. I have been struggling with rats nesting and eating in my engine compartments for several years. Every morning I had to pop the hood and clean the droppings and check if there was any damage. I started setting traps and that worked when you caught the rat, but it was cumbersome to dispose of the dead rat and re-bait. I tried peppermint oil on cotton balls under the hood which seemed to work most of the time, but still wanted a better solution. I got this as a friend said ultrasonic device worked for his garage. I have the unit placed by my backdoor facing the back of my car, set for evenings only, and have a solid gate in front of my car and a fence on either side of my car so I guess the ultrasonic waves flood around my car. I have had it working for 1 months now and it works I have only found traces of feces twice but small quantities, nothing like before. The unit comes on for a few seconds and then turns off. It seems like the rate may go into the engine compartment but then when the unit turns on it scares it away. The only thing I can complain about is the power supply, the unit can not run on batteries. Overall good product.

Since I plugged dose all over my house I can leave window and door open all day long I am not seeing any little creatures around my place at all.. I live in Florida and we were surrounded by all sorts of lizards roaches in outdoor creatures they want to come in to stay cooler since I purchase this thing I haven't seen a lizard or anything trying to get into the house and I keep the windows open the Lanai all the time. I have a little dog and a cat in the house and they don't seem to be effected by those.

I put three of them at home. It's is a little complicated to evaluate/measure if they make their work or not, but being honest I think that the answer is more like a Yes. I've noticed a reduction in the number of bugs and mosquitos that get into the home, and maybe with the roaches that from time to time I could found. I'm not sure about Ants because I'm still seeing them if my kid leaves cookies on the floor.

I've been using these for a couple months. They did repel mosquitoes for one day, but by the next day the mosquitoes were ignoring them. They definitely do not repel rodents either. I plugged them up around my Quail pen, because the quail feed tends to attract mice. After 2 months the mice were still hanging around the quail pen and even managed to get inside. Thankfully the mice tangled themselves in my bird block netting and I was able to dispose of them.

I can't believe myself that I got a product which does nothing other than giving night light! My main goal was to get rid of spiders but even after plugging it for more than 3 weeks I see those little creatures within few inches of this plug. What a joke that I paid $25 for 4 led lights in the name of environment friendly pest control. No free returns :-( .

Did not work at all for insects in my house. Plugged it in and the ants on my counter didn't react at all :( Neither did the spider hiding in the corner. Left it there for days, seemed to decrease at first, but then they all came back. Spiders and ants everywhere :(
