Bird-X Transonic Pro Electronic Ultraviolet(Uv) Light Units Pest Repeller, Black

this device does what it has to do and is very effective.

Not as big as it looks ..a bonus..we haven't used it yet just getting ready for autumn to kee verminnout of our new sheds

Don't know why it is called bird-x-transonic it is ineffective with birds, it states as much in the info leaflet. Works great on any other problems you may have though.

The sound is audible so not to be used in the home, I have put it in the loft on the lowest setting the sound can’t be heard, through the ceiling. Only been up there a few days so don’t know how well it works, it makes a very annoying noise I didn’t want to be anywhere near it.

Didn’t realise the noise was audible to humans too noisy to use in house

Since I use it we don't have a problem with rats.

ok
