What keeps mice away?

[Charlief]

The shed at the back of my property has some new tenants.  Mice have moved in and I need to get them out.  Getting rid of them won't be a problem...... but how do I keep them away?

I have read that moth balls might work.  Any one have any FHE with deterrents? 

I'm going to go through the shed (8'x12') and seal all possible openings with spray foam. 

I might just end up spreading poison all around the shed but I don't want to harm any other animals in the area.  I don't have to worry about any dogs/cats  getting to the poison.

I've had moth balls work quite well for garden pests.

I would think they'd be effective for mice as well.

I've had good results sticking steel wool in all possible openings.

Sorry, no FHE with a deterrent.

If you have owls where you live, maybe you could try putting up an owl house?

+1 on the steel wool.  I wouldn't waste money on the foam.  Fill the holes full of steel wool and put metal flashing over them. 

Barn cats work wonders on furry and feathered critters......

i dont think you will ever keep them out.
put decon inside the shed.

You did seem to have a good crop this year.

Has anyone ever just tried a "No Mice Allowed" sign?

I NEED to keep the mice out. I just bought a new John Deere tractor and if those make the beast with two backsers move back in I'll be pissed!

Cats are not an option because... Well.... I hate 'em.

I'll probably go all out and buy every trap/poison available.

Steel wool shoved into the areas and held in place by the spray foam. Rodents don't like the steel wool feeling on their teeth...

Option 2
Giant centipede eating mouse.

I like number 2 as now you also get a nice cuddly pet.

Bounce dryer sheets.

(yes, really)

I've used them in stored cars for years - and in the spring the car smells fresh! Not sure how you'd apply to a building, other than tossing them everywhere (or packing the nooks and crannies with them).

I read that on line also and thought... no way.  Hell  I'll cover the floor with them!

Mice can chew through most anything except steel wool.

Even concrete wont stop them.

Also, they can fit through an opening the size of a dime.  Or so I've read.

I like the centipede idea.  Just get a bag of those and release them in the shed.

Problem solved.

every year we pack our combine with moth balls, and it works pretty well, except it only seems to work in smaller enclosed spaces, I don't think you can just scatter them out in an open area and have them work, if you had a cupboard or something you wanted them to stay out of the moth balls would work, but I don't know about a whole shed.

Moth balls don't work on Bronx squirrels.
