Ultrasonic Pest Repeller - 6 Packs Electronic Plug -In DOUBLE IMPACT Pest Control Ultrasonic - Best Repellent for Cockroach, Rodents, Flies, Roaches, Ants, Mice,Spiders, Fleas

I highly recommend this product! I only wish I had bought these sooner! After unsuccessfully using Tomcat bait traps for almost 2 years and watching the bait disappear, but the mice remain, I purchased these wonderful devices. Two days after I installed them throughout my home I caught 4 mice in traps. Now, for over a month I have not seen a single mouse, nor have there been any new droppings!

While these look ok, they seem very cheap, light and hollow. And it’s beyond me WHY they make the plug so that it will cover up part of the 2nd receptical!!! So if the thing is plugged in one, you can’t use the other.

Have no complaints. Product arrived promptly and has been placed into service.

I waited 2 months to see if this product would work and unfortunately it didn’t. I purchased it to get rid of the mice that keep coming in our house but it didn’t work at all. We also have ants and it didn’t help with them either. I was really hoping it would help. Looks like an exterminator will be my next step.

I don't think these worked on spiders, I've seen 2 crawling by these and one was less than 3 feet from it. Great night lights right now.

Does not work, and takes up needed outlet plugs space.

If these things worked I would hate to see my house if they didn’t! Every spring I used to get deluged with lady bugs, but for the last couple of years, it has been stink bugs. I didn’t feel these helped. After a year, I tossed them.

The mice are GONE from my travel trailer!
