Although some people keep mice as pets, mice generally are a nuisance. These rodents chew through items, leave droppings and spread disease. Mice typically enter a home simply because the home is warmer and contains food--they actually are quite shy. If you have a mouse problem, you can use some household products to get rid of the mice, although you'll still need to use the products with some caution.
Inspect your home and identify areas through which the mice are entering. Place steel wool or insulating caulk in these areas to seal them off--the mice will get sick if they try to eat or chew through the caulk, and they usually leave steel wool alone because it is hard enough to cut their mouths if they try to chew on it. You also can use expanding foam, which sometimes is used in place of caulk for insulating to fill asymmetrical or hard-to-reach places. Expanding foam should be the last choice, however, because it hardens very quickly and can be difficult to clean up if you make an error in installation.
Get rid of or seal in airtight containers any items that might serve as food sources to the mice. For example, mice especially love grass seed, but most will eat just about any meat, seed, vegetable or fruit, according to Pet-Mice.com. No matter what product you use to get rid of your mice, it will be ineffective if the smell of food attracts more rodents.
Experiment with scented items to repel mice. Stick cotton balls soaked in ammonia or peppermint oil in areas where you see droppings or evidence of mouse activity, or in areas where the mice might be entering your home. Mothballs also work, says the website To Get Rid of Mice.
Mix plaster of Paris with a food that's attractive to mice, such as cornmeal, flour or even chocolate powder. Place the mixture in an open container where you suspect mice are present, along with a second container of water. The mice will eat the mixture and, as they are poisoned, seek out the water. The water will react with the plaster of Paris, which will get hot and burn the stomachs of the mice. Try to put the powder in an accessible area and limit the routes the mice can go to die, because you don't want their carcases to rot in your walls, floors or ceilings.
Dispose of any mouse carcases you can reach. Thoroughly wash areas in which you have seen mice. Mice urinate as they travel through your property, and other mice are attracted to the urine scent because it signals the possible presence of their own kind. This essentially gives new rodents the green light that your home is mouse-friendly. Put a few drops of peppermint oil into your cleaning mixture to discourage new mice even more.
