Category:Mice

Living in the country with a lot of bush and fields around can lead to severe mouse trouble because there's effectively an infinite supply of them, so whatever population your living area supports will always be packed full up to that limit - the "carrying capacity" of your house! Killing them or trapping and transporting them is just a waste of time and energy because removing them simply creates a vacuum which will be quickly filled by the surrounding population.

So the only answer is to reduce the carrying capacity of your environment, and to make sure your house is well sealed against them. Sealing against them means that every tiny whole in the foundations or roof such as under corrugations must be filled. Ideally with concrete or wood, but for the more difficult areas steel wool is a good option. Also putting peppermint oil around can help to make the area distasteful for them as the smell is too strong for the little critters.
