## Description

Sponsored Ad – Ultra 400 Ultrasonic Mouse & Insect Control Plug In Pest Repeller 400sq ft Room - All In 1 Mice, Rodents, Spiders, Rats & Crawling Insects - Single Unit

## Features

- How does it work?: The Ultra 400 emits out a powerful, continuously varying, high frequency ultrasound - for rats and mice who can hear at frequencies much higher than humans, it's like a smoke alarm going off continuously. - insects and other crawlers are thought to be similarly affected by the high frequencies.
- Easy to set up: Just plug in one Ultra 400 device for each room where you might have a problem - one device will cover 400 sq ft (that's about 4 times the size of a standard double bedroom)
- Continual frequency changes: Continually sweeping frequency changes reduce the changes of device-adaptation
- Safe & Nontoxic: Safe for humans, babies, cats and dogs
- Guaranteed to Work or Your Money Back - we are so confident that this device will solve your problem that we'll give you your money back, no questions asked after 60 days.

    Don't bother.
  

*by G***E on Reviewed in the United Kingdom on 25 February 2015*

I purchased these to try and help deal with a rat that had decided to terrorise me. I discovered, with the rat setting up home in my wall, that I do in fact have a phobia of the things. I plugged these in all round my house and hoped for the best and to be fair activity was reduced for the next two night. Unfortunately this was the sum total of the effect these had. By the third night it was back to tap dancing in the walls and, to my complete horror and leading to a partial breakdown, had also chewed through the ceiling and had gained access into the actual house. I quickly realised my only options were the men in white coats or a professional pest control company. I'm sure you'll be glad to know I'm trying the professional pest control people first. They are now in the case and dealing with the situation. They are a lot more expensive than these plugs were but it turns out the saying "you get what you pay for" is very true.As a side note, if the critter that moved in with you doesn't sent you bonkers the constant clicking these things produce might.So to round up, these don't work and, in my experience, apparently only poison really does. (Please note Cayenne pepper, peppermint etc. are all as much use as a hole in the head also)

    Doubtful effect
  

*by M***I on Reviewed in the United Kingdom on 22 July 2020*

Neat gadget. Yet to prove its usefulness.spider has been seen since installation in bedroom. Some people may not like the tick noise but it is quite quiet.
