Ultrasonic Pest Repeller, Indoor Ultrasonic Repellent for Roach, Rodent, Mouse, Bugs, Mosquito, Mice, Spider, Electronic Plug in Pest Control, 6 Packs

We returned home from a lengthy vacation to find a mouse eating grass seed stored in our basement. We did our homework and found these to be the best choice per the reviews we read. Excellent choice. Love these! They work. In about a week or so the mouse was gone. No mosquitoes, No crickets or spiders in sight as well. We also realized the squirrels weren’t running across our porch roof anymore. We have these spread throughout the house, all in silent mode except the one in the basement. We can’t hear it from the main floor and thought having it on we be good as an extra layer of protection. We even put one on our enclosed porch. These are awesome and pet friendly.

So this is my opinion, it does work to some degree. Is it a magic cure all, NO. I used this to both repel bugs and later found out i already had a infestation when i started using this. So in my opinion if you have bugs in your house like i had roaches. It will bring them out of their hiding places, it won't kill them and they likely won't leave your house, they'll just be very disturbed and visible. Now I naturally panicked and became a exterminator and did so many things (some probably hazardous to my health) to kill them. They eventually went away but i can kinda correlate them all the roaches coming out after i used these devices. BUT AGAIN IT WILL NOT SOLVE YOUR PROBLEM, IT WILL EXPOSE YOUR PROBLEM AND MAY PREVENT A FUTURE PROBLEM

I thought I had written a review after getting frustrated trying to contact the seller d/t not receiving all 6 units. My mistake, one fell out of the box and I just found it. Now I can't find that review so I'm assuming I did not hit submit. I received (all six) quickly, late in the day.I found droppings last year after I moved in and found where mice had chewed through some food packages. Apartment management put two traps in my kitchen which the mice ignored and I finally tossed them. I bought larger plastic storage containers to keep anything they might get into and that has helped a lot. This year I didn't see droppings when the weather turned cold. I saw the mice. The apartment management again put two black traps which the mice ignored but seemed to attract ants. I complained again when I saw mice under the baseboard and another time coming out from under the stove. Next day I come home to lumps of poison on three paper plates in my small kitchen. I don't want poison in my kitchen. I don't want to kill them, just make them go away. The night they arrived which was two days ago I was tired, thought I'd read the instructions and plug them in the next day. Sitting on the couch thinking about heading for bed I hear little feet in the heat register, again. I grabbed the units and plugged them in. I have a two bedroom apartment under 1000 sq ft. I put one in the living room, one in the dining room and one in each bedroom. That was two days ago so I can't say how effective they are yet. There is a button on the front, push once for inaudible for smaller pests, press again for audible for larger pests which is faint but I can hear within two or three feet. There's light on it when you press the buttons to indicate what level you're on. Listings says each unit covers up to 1300 sq ft. I figured one in each room. Can't do the kitchen or bathroom as I don't have an outlet closer to the floor. So far so good. I thought I heard something last night, little feet on metal sound. Then, it could be my imagination but a tiny yelp and feet runing away in the other direction. Maybe I was just too tired and hopeful but I'm hoping it was the effect of the Zero pest repeller and that it means it's working well. I would promise an update at a later time but we all know that's not going to happen! Like one in a thousand people actually post an update when they say they will. So fingers crossed! Oh, I lent one to my neighbor next to my apartment who said she can sit there and watch them come from under her dishwasher into her apartment. Hopefully she will be able to tell if it's helping. Oh and...maybe it will help with the ants and the flies in the summer! Hopefully!

I live in a housing development in a rural area with a lot of trees and shrubs, so I have a lot of bugs (spiders, flies, centipedes, wasps, and wood beetles) and the occasional mouse in the garage. These absolutely work to eliminate the pests that paraded around every room in my house, with the spiders and wood beetles being the boldest. It did take the 3 to 4 weeks described to notice a significant reduction, and I see fewer and fewer bugs as I continue to use these.These did not eliminate an infestation of fruit flies or other flying insects, but a couple plug-in sticky cards worked well for that (with no dead bugs laying around).Once in a while, a determined wood beetle enters the house, but I notice they are disabled and easy to catch and suck up with my trusty hand vac. But crickets, centipedes, and spiders are gone. No more parades around the floors, crawls up the walls, or dangling from the ceiling. Now, I just need to get rid of all those cobwebs and take back my home.What I would change:- These must be reset if the power goes out, so I don't recommend them for an empty or little-used home. Choose a version that automatically works if the power is restored after a power outage.- The lavender light is supposed to draw flying insects, but I find the lights unattractive and indicate that I have bugs. There are better options for flying insects. You may want to choose a version where you can switch the light on or off, especially in a vacation home, rental home, or building you are selling.These things work! For the price of just one pest-control service call, you can install these in every room in the house.
