What is this gadget?

[Throughtheroof]

At holiday house and this was plugged in to an adapter. (Also plugged in is kettle and dishwasher).

There was a clicking noise coming from that area and when I pulled out this gadget it stopped.

But I've got no idea what it does. I've looked at Koolatron.com and it seems to make cool bags and such like.

Anyone know if I have unplugged something vital?!

Isn't it an air freshener thing?

A pest repellent

Specifically mice and rats....

You might want to plug it back in 😆

Thanks. Ok so neither vital - although I'm a bit concerned about pests now!

The place does have a noticeable air freshener smell, so maybe that.

Mouse repellant not that they work

Oh yuk. I don't want a mouse or a rat on holiday!

I might plug it into an empty socket. Don't know why it has to be added to an adapter.

Are they supposed to click?

They don't work so don't worry about it !! As it's summer you probably won't see any.

It’s a sonic anti mouse thing. We’ve just found one in our cupboard.
