How to Keep Mice Out of Your Garage

The Cheapest Ways to Keep Mice Away

There’s nothing cartoon-cute about a mouse in your house or garage. These little rodents, in any climate and at any time of the year, can gnaw their way through wood, metals, wall insulation and even electrical wiring, according to the experts at North Shore Commercial Door.

Worse, they can carry and transmit any of more than 30 diseases, from rat-bite fever to the plague, according to the U.S. Centers for Disease Control and Prevention, or CDC.

Internet websites are awash in so-called remedies on how to naturally keep mice away, from inexpensive peppermint oils to expensive electronic sonic-sound gadgets. But there is no evidence they work. Mice easily adapt to smells and sounds, reports the CDC. Buy a cat, and the cat can become infected or carry in fleas infected by mice.

How to keep mice away involves first getting rid of any mice that might already be on the premises.

How to find the mice

  1. Teeny, tiny barrel-shaped droppings, faint scratching noises and a strong scent of urine are the most obvious evidence that mice have already made their way into your garage or home.
  2. Look for gnaw marks around cracks, crevices and gaps. Mice can climb 12 in. (30.48 cm) high, so search accordingly. Wood shavings can indicate they have gnawed their way inside.
  3. When you see gaps and holes as tiny as 1/4-inch (.635 cm) in diameter in a wall, door or baseboard, fill these potential mice entryways with steel wool before you cover them.

How to get the mice out

  1. Inexpensive wood and wire mousetraps that are baited with peanut butter and placed every few feet around walls can catch and kill mice. The CDC recommends against using “live” traps, because they can cause startled mice to spread infected urine.
  2. Rat poison can be fatal to more than mice. The University of California Integrated Pest Management Program advises the use of government-approved toxins safely contained inside rodent-control bait stations.
  3. When removing dead mice, wear gloves and air out the garage or house, since diseases can be transmitted through direct and indirect (read: dust) contact with dead mice and droppings.
  4. If your house or garage is infested, hiring a professional exterminator can prove cheaper than the danger to your health and costly damage to your home or business.
