We live in the bush, mice are rampant here. Our cat keeps them at bay. We have never seen one in the house in the 11 years we've had her.

You'll probably find there is a nest under your house somewhere. Mice usually only go into the house one at a time to take food back, or so I'm told. You have to kill them at the nest. Put Ratsak under the house, in the roof and in the cupboards you hear them rustling around in.
