Yes, Joybel, mice can get into any space it seems - really tiny holes. Or they make their own. Poison is truly the best way I know to get control of a plague of mice. That and trying to make sure you don't leave the merest crumb of food for them. I hope you have a fridge? They don't seem able to get into them; pantries, larders, cupboards, safes are open to them. Our mice chewed through the solid wooden backs of the cutlery drawers to get access to a few bread crumbs I'd inadvertently dropped in there when wiping down the benches. Vile little beasts.
With the poison baits, which cause internal bleeds and of course great thirst, at least they go outside to find water and die out there not rotting away in your roof spaces or under your floors or in your walls. Yuk.

"We live on first floor on our Retirement Village apartment Complex. We have "Rodentwatch" We have four hungry cats stationed @ the staircases and we are using as well " Rodentbait" They tell me its some beer made North of Bombay Hills which was not up to our std. It certainly blows their mind & slows them down and our Cats are "FATCATS""

I've seen where mice have chewed through loudspeakers in a cabinet - eaten up all the black paper cones and left the wires sticking up in mid air.....

I have a sneaking feeling I am having my leg pulled.

Not by me, Joybel, I'm sorry to say.

Hordes of mice at this time of year are a common and horrid experience in the countryside. Perhaps the devastation and reduction of food sources in Christchurch is causing it in the city and suburbs? Certainly the sort of damage they can do as stated above is pretty much right.

I should think the Council will have to help residents to pay for eradication - poisoning I suppose?

Nor me .....when my garage and car were invaded afew years ago (in spite of Tom) I discovered those wonderful easy set mouse traps!

Nor me Joybel!

Bloody mice are the last thing to joke about!

Once they find an easy meal they seem to call every mouse from miles.

Not long after I was married we brought a country Dairy (And went broke, but that's another story) and with it being an old building with plenty of hidey holes we were just about pulling our hair out.

Our saviour was poison. We found that if we put it out in an open dish/container or what ever they would turn their noses up and not touch it. One of the Traveler's put us right in the end, the secret is to put the packet out and just rip the corner just a little so they have to work at it. If it's too easy they become suspicious!

So they have a brain then and not just sex maniacs reproducing every seven weeks. If I put packets in tins, that should help, eh! There is a relation of the squirrel in Iowa they call a squinny. It is a bit fatter than a mouse and it has jaws of a shark the way it can eat through drink cans squashed and pushed up basement drain outlets. Family bought a system which kills by an electric charge. I was sorry for the wee thing until I saw the can it had eaten through to get inside.
