4-in-1 Ultrasonic Rodent Repellent Plug-in Electronic Mice Repeller Rat Deterrent, Pest Control Device with Ultrasound, Electric Impulse, Flashing Lights, Predator Sounds, Indoor Mouse and Rat Control

We live in the country, so mice are unavoidable. We have five cats and a dog, so we don't use any kind of poison or dangerous chemical deterrents as our cats have gotten ahold of some mice. If the mice are poisoned and a cat(s) eat them, it would be too late before we realized what happened. We take other preventative steps like not leaving any pet or people food out, putting down pet safe mice deterrent, etc. We also have baited snap traps all over, but mice still sneak into the house. Our pest guy said that without poison baiting, it's going to be a constant battle since mice can get into a house through the tiniest openings. And having a house in a place where mice have significant numbers of natural predators is a spot said mice will seek out for safety. Living across from a nature preserve with several species of predators such as eagles, hawks, coyotes, foxes, and such makes our house probably look like the Hilton.Based on research we did with pest control blogs and sites, several animal control websites, and other house tip sites, they all say it's a toss-up as to whether or not electronic pest control works. This plug-in model and a couple other battery powered electronic gadgets like this have been installed and running 24/7 all over our house for five or six weeks now. Since starting this latest round of preventative measures, the number of mice seen anywhere or caught in traps has gone from once (or worse, twice) a week to ZERO. None in the traps, none caught by our cats and used as toys, none brought to us in the middle of the night as a present. The one thing that has changed in our battle is the addition of these electronic repellers. Our cats may not be happy at the reduction in play toys, but we're not and neither is our pest control guy. When we set these up, he wasn't able to tell us if they'd work or not, but even he is impressed that after using these, we can't deny that there has been a major reduction in mice. Even though it's freezing outside and mice usually head inside to seek shelter from the weather, this winter is nothing like winter last year (2019-2020) where we had to double our efforts against the stupid mice.These units are very easy to operate. Plug them in, select a setting, and you're set. We have the plug-in models in/around our bedrooms, so we don't use the strobe light option, only the sonic setting. Our pets aren't bothered by the lights or the range of frequency noises put out through the speakers. The units are small enough to be put almost anywhere as long as it's within 3' of an outlet, and they are pretty unobtrusive. There is a little green light that blinks and lets you know that it's on and working, but it's not something that will keep anyone awake. Even in a dark hall it's barely noticeable.As far our experience, these have been a massive help in our fight against mini couch surfers living rent free in our house. We aren't going to dispense with the traps or pest guy, though. If anything we will add more of these electronic repellers.

I wanted to try out something to get rodents out of our attic since they seem to be eating everything including wires in our HVAC. I got this and tested it out prior to putting it into the attic. It’s really tiny only about 5 inches high so not too difficult to find a place to use it. The AC cord is not too long to allow you to place the device too far from the AC outlet without an extension cord. I placed the device on a bucket to it was more visible while using the strobe lights.There are 3 audible settings and Test mode: Ultrasonic waves, Duo-impulse and ultrasonic, Trio-impulse, ultrasonic and predator sounds (very loud animal sounds). I used the test mode to listen to the sound levels (it has an adjustable volume). I am using the Duo sounds since the animal sounds are pretty loud and can be heard from the attic. I love the LED lights that alternate between pulses from three different light bars on the top of the device. I looked in the attic and the strobe lights are still rotating and visible throughout the whole attic.So far I think the audible sounds and led strobe lights are annoying the rodents. I haven’t heard anything in the attic in past week so this may be what we need to keep the critters out. I’m pleased with the device’s easy operation and small size.

The crawl space in our 1901 home is the stuff of nightmares. I swapped out the traps for this unit, set it to strobe and blare, and a week later a disgustingly familiar citrusy floral dank smell started wafting into the downstairs. A rat literally cuddled up to this thing to die. Some fireplace tongs, a velcro ripping sound leaving tufts of matted fur behind, and then some industrial cleaner and telescoping scrubber... This unit went into the bag with the rat. It seemed apt - the rat clearly loved it to death.My advice: save your money, buy a simple classic trap, bait with peanut butter or beef jerky, and set the trap inside of a paper shopping bag so you don't have to scrape matted blood off of the floor.
