If you wish to keep the mice out of the garage, you need to make your home inhospitable as well as impenetrable to rodents. That is not an easy thing to do and one has to keep putting up their guards against such creatures after every short span of time. If you wish to keep the rodents out of your home, set up a good defense system. Even if it sounds hilarious, rodents are clever and they will find weak points to enter and wreak havoc in your home. Considering the amount of impurities they carry and pathogens they leave on the surfaces they run or touch, you need to be alert and take steps promptly.

Some handy tips to consider:
Lawn or green surfaces round buildings or homes are the places where rats and mice come on first. One could make the lawn inhospitable by cutting back vegetation. This usually serves as source of food and shelter for them. There should be a significant gap between the garden and your home. Trim the trees and shrubs in order to have plenty of exposed ground which the rodents will not like. In order to keep the rodents away from your garage, seal the entry points. Rodents can crawl through holes the size of a dime. If there are exterior vents or pipes in the garage use steel wool, hardware cloth or metal sheeting to block the gaps around such entry points. Put up screens on open windows.
Rodents can even burrow underground to access a home. If such underground entry points are present in your garage, make a trench of pea gravel to stop their advances. In such ways one can ensure that the rodents do not land up in their garage or get access to one’s home. If such measures fail, one can seek the assistance of pest control authorities.
