How to Get Rid of Deer Mice
If left uncontrolled, deer mice can be troublesome and dangerous pests. They are the primary reservoir species of Hantavirus Pulmonary Syndrome, which is extremely harmful to human health.
Prevention measures may be taken to ensure that an area does not become host to a deer mouse population. The use of rodent-proofing materials on entryways around the exterior ensures that these rodents cannot enter. Regardless of size, all holes should be sealed with these materials; deer mice possess soft cartilage that allows them to pass through holes less than the size of a dime. Keeping weeds and grass mowed and removing clutter from the yard can make the property less attractive to deer mice.
Defensive packaging of food will also help. Food containers made of stainless steel, glass and thick, heavy plastic are better than paper boxes and plastic bags.
Boxes and items stored in garages, attics, or crawlspaces are ideal nesting sites for deer mice. These should be examined carefully. Try to "de-clutter" these areas so that mouse activity will be easier to spot.
Removing deer mice from the infested area oftentimes proves difficult. Most methods involve the treatment with traps or toxic baits. Baits should be used with extreme caution according to label directions to avoid harm to children and pets. Professional pest control treatment may be necessary to treat an existing deer mouse infestation.
