How to get rid of mice fast
Keep your food sources in metal or glass containers with secure lids.
Mice can eat through cardboard, certain plastics, and other forms of containers to get at food. In order to cut down the mice's food supply, make sure that you don't leave any food out, or if you do, to put it in something that mice cannot get at.
Don't leave out pet food. Remove any food that your pet hasn't eaten immediately after its meal.
