Stop mice from going under doors

[smthngStupid]

Can anyone recommend anything I can put under my bedroom door to stop this happening tonight? Emergency solution!

Towels?

A towel or t shirts stuffed under there quite tightly?

We've used chicken wire which squares up nicely and into gaps.

Mice can dislocate their skulls and slip through a gap the size of a pencil.

Squashes

Freudian you beat me to it

Towels, or clothing, stuffed under should work OP. (Have been there myself which is why I now own 2 cats! Bastard mice!)

Scrunched up kitchen foil works quite well. They don't like chewing through it. I used to use it to stuff up mouse holes in my flat.

In this house the only reason there would BE a mouse in the house is because the bloody cats had brought it in and got bored ....

Mind you mice are nothing compared with the live baby rat I had to catch at 4am - emerged when I straightened the bath mat at 4am while on the loo!

Mice can get through the smallest of spaces. Whatever you use, pack it well!

Hardback books, in a line along the door. And later get a piece of timber exactly the width of the doorway and squish it down to the floor to raise the threshold a centimetre or two. I've done this to all my external doors and have never stubbed a toe.

Long term solution (as advised by council pest catcher when at Uni ...) is to sweep up religiously, and leave no crumbs or flakes of food around.

It does work.

Wire wool and a sprinkling of cayenne pepper.

Peppermint is a deterrent apparently.
We had one in our side porch once. I took a length of garden cane and cut it to the door width then pushed brillo pads onto it all along it.
In guessing it worked as mousey never made it into the house.

Traps.

They don't like carpet pythons, but they're hard to get in a pinch. Definitely the tinfoil thing. I'd be tempted to burn the house down.
