Hi Zavara,

I'm in the Wimmera and we are in the middle of a mini mice plaque here too.

We use baits and traps. I don't know how many times I've gone to the toilet (which is in the laundry) and a mice has run between my legs. (they were coming up through a gap between the toilet pipes.

I too use steel wool to try and cover up any holes. We had used poly filler but the little buggers have got through that.

I was given another tip you mix together cement powder and custard power 50 50 mix, just leave in a say aluminium tray, it works like bait, they are attracted to the custard powder, eat the mixture then the cement draws all the water out of them and kills them. They won't smell as bad as baited mice do when they die. (or so I have been told I haven't tried this one yet)

Good luck!
