Identifying where mice are hiding in your yard

The first step to get rid of mice in the backyard is to find their hiding spots. Field mice, house mice, and deer mice are some of the most common species of mice in yards. You may find their nests in places like dense shrubs, under decks, or inside burrows in the ground. Common signs of mice in your yard include droppings, chewed materials, pathways or tracks in the grass, and evidence of nesting, such as shredded grass or leaves. Mice are often attracted to food sources, including fallen fruits and vegetables, bird seeds, and pet food, as well as areas that provide them with safe hiding spots, such as piles of debris or tall grass.

How to help get rid of mice in your yard

Although mice are small, these pests have high reproductive potential. For example, a house mouse can have five to 10 litters of three to 12 offspring each year. Field mice need access to food and water, and when resources become limited, they can easily find their way indoors through even the smallest openings. Fortunately, there are effective strategies you can implement to make your yard less inviting to these rodents over time. Want to know how to get rid of mice outdoors? Check out these tips.

Clean up your yard

Wood piles, tall grass, and piles of fallen leaves all make great hiding places for mice. Try to keep up on yard work by regularly cutting your grass and pulling any long weeds. Also, remove any piles of wood and foliage that provide potential hiding spots. If you compost, try moving the materials as far away from your home as possible and keeping them in a sealed container.

Remove exposed food

Bird food, pet food, and trash are all potential food sources for rodents. Be sure to seal your trash cans with a lid that locks. Keep any uneaten pet food or bird seed in a sealed container inside your garage or home to prevent access to mice. Plant vegetable gardens away from the home and avoid seed-producing plants like sunflowers.

Set baited traps

One of the best ways to get rid of mice. is to use traps. You can use baited snap traps, glue traps, or bait stations around the areas that you see mice frequenting. Mice will typically run close to walls and are unlikely to travel more than five to 10 feet into an open space to retrieve bait. Be strategic when setting traps by placing them along the perimeter of your property and away from spaces where your pets or children can accidentally set them off.

Cover burrow openings

Mice and other rodents may create burrows in the ground for nesting, resting, or hiding. These holes can be one to four feet long and can extend several feet underground. To get rid of field mice, cover any holes you find in your yard with a six-inch thick covering of pea gravel, as these may be entry or exit holes for rodent burrows. If you notice an opening has been dug up again, you may still have a mouse problem.

Inspect your home

Once your yard is clean, all potential food sources have been sealed, and you have set traps, the next step is to prevent mice in the yard from entering your home. Examine the exterior of your home for any holes or cracks where mice can enter, and seal any openings with wire mesh or caulk.

Will natural repellents get rid of mice in my yard?

Natural repellents can be effective to help get rid of mice in the backyard. Some smells that mice hate include peppermint oil, coffee grounds, vinegar, and ammonia.

Ammonia for mice, in particular, is thought to mimic the scent of predator urine, which can discourage mice from lingering. While these natural repellents can be somewhat effective, their efficacy may vary depending on the severity of the infestation and environmental factors.
