Victor M793 Ultra Sonic Pest Chaser Rodent Repellent - Repel Mice and other rodents

Problem: field mouse running in the attics, and recently, one timely and consistent racoon came down the trees on to the roof and ripped a small gap on the side allowing the said racoon (and more mouse) to get in and out the attic. We have several fruit trees in the yard, so I believe these small animals are here for the buffet. Drove me insane around 1-2am. Got the Victor M793 after reading Amazon reviews, ordered it around 1:45AM and received it by 5PM, plugged it in, and started to work slowly night by night. The first and second night, yep like clockwork, I would hear the racoon coming down the tree, running across my roof, same route to the place where he/she clawed a gap. BUT- with the repellant on, the racoon would not enter. The mouse problem also improved because I do not hear little footsteps running inside of my ceiling anymore.You'll have to put it in the right place allowing the sonic wave to travel, place it somewhere central and point it to the general direction where you've been hearing noise the most. When you turn it on, it has a very faint buzzing sound, my dog doesn't seem to be affected by it. The M793 also has a pulsating red light. Not police siren red, but a dim kind of red. I guess small critters will find it annoying, even blinding?!??We live in the suburbs of LA. We have the usual urban small animals running through our yard grabbing fruits and finding shelter- possums, squirrels, rats, mouse, stray cats. The worst on the list are skunks and racoons. I have "mastered" skunk- Havahart cage and a generous wad of peanut butter- done! Racoons come down from the trees on to the roof, so they're a bit more tricky and sneaky.I have this machine on every night since purchase on 5/29/2015 and today is 6/30/2015. Haven't heard any noise in my attic or inside my roof since the purchase, so.... highly recommended.

Works great

I don't know if this particular one is defective, but bought two from Lowe's which would be the model with two speakers and those had some noise that could be heard. This one, however, is completely silent. But the reason I have to return it is that it has absolutely no effect whatsoever. I live near a park and the rats are aggressive! They chew through the house into my kitchen. The bait blocks worked at first but through natural selection those that didn't munch on them survive. Now I have to find other ways. The small ones that you plug in like night light all did not work or worked for only a few months - I tried four or five brands. Yes, you should be aware that those little ones even when they work, they only work for a period. The rats get used to them and come back! So I'm on to these bigger ones from Victor. Also, when I'm gone on vacation I intend to use ozone generators to make the environment absolutely unlivable for these rats. It's a war alright. Sometimes you win but over time, the rats prove how they have always survived to pest us and keep us on our toes trying to invent the better mouse traps!PS - I'm redeploying the two-speaker model to the kitchen. It was placed elsewhere because I wanted to put this more expensive three-speaker one in the kitchen. Will see if that one actually works with the little audible noise that it makes indicating that it at least turns on or does something.

A humane way to keep rodents at bay. I'm using it in an oversized, detached two-car garage. Not sure if it actually keeps them away, as the garage is huge and has tons of boxes, totes, and crates in it. Probably two backed up against each other would be better to have a 360 degree protection, but currently only have one. It says it doesn't penetrate walls or lots of furniture. I like that it does face three directions and would work great against a wall in a room in the house.

I never believed these electronic pest repellers worked and some of the cheaper ones I bought didn't. This one actually works perfectly for mice. My apartment building is infested with mice. My downstairs neighbor has 3 dogs and leaves food out for them all the time. He also never cleans and you can see pizza boxes piled up in the kitchen through the window. It's the perfect home for mice. Eventually, the mice climb up through the walls into my apartment. One year, I caught 7 mice over 2 nights. I had gotten some cheap electronic repellers, but eventually they stopped working. I bought some others that didn't work and within a week, I had mice in my apartment again. I was hesitant to get this one because it's quite a bit more expensive, but I gave it a try. I haven't had one single mouse in my apartment since. I know exactly where the mice come in, through a hole for the plumbing behind my dishwasher, so I set this repeller on the floor pointing right at that spot. I never even hear them in the walls anymore. I've had friends bring dogs and cats to my place to visit and they don't notice the unit at all. This isn't the cheapest pest repeller, but it does work great. If you have a big problem with mice, it's worth the money.

I don't know if rodents get used to the sound or if the product stops working. It did seem to help for a month or two, but then I started finding signs of them returning. Back to the traps. Really wish I had just stuck with traps and saved the money.
