House Mouse

House Mouse Control

House Mice control can be accomplished by snap traps, glue boards or multiple mouse traps. They have a tendency to store food. If using a baiting program it is best to use a bait blox used with a rod in a Mouse Protecta Bait Station, so they don't carry the bait off for storage(such as pellets) for later consumption. Baits should be placed close to the suspected activity.

About House Mice

Since mice have a higher population number than rats, they are more widespread.

Do I have a house mouse or a young rat?

A young rat's head will be proportionally larger to its body a mouse's head or their feet as seen in the Field Identification of Domestic Rodents. cdc field id

house miceThe adult house mouse is small and slender and about 1-2 inches long, excluding tail. The house mouse has large ears (as seen photo below), pointed nose and small eyes. The tail is as long as the head and body combined. The fur color varies, but it is usually a light gray or brown but could be darker shades. The House Mouse weighs about 1/2 to 1 oz as an adult. Mice can be identified from young rats by the size of the head and the hind feet.

House Mice Diet

A mouse prefers seeds, cereal grains, or sweets but will eat almost anything. Mice do not need much water; they get most of their water requirements from their food. Farms and granaries are often infested with mice as they eat large quantities of stored seed and grains.

House Mouse Habits and Biology

If food water and shelter are available, mice can rapidly multiply. Mice become sexually mature in just a couple months and produce about eight litters in one year. Each mice litter has 4-7 pups.

A house mice in a city environment may spend its entire life in buildings. In rural and suburban settings, it may not only live inside, but be found outside near foundations, in the shrubbery, weeds, crawl spaces, basements, or in garages.

Mice can live remarkably well on insects, seeds, and plants, but when the cooler months approach, their food supply is limited. They may move inside homes and buildings and nest closer to a food supply at this point. Mice nests can be in various locations. They may nest in ceiling voids, storage boxes, in walls, under appliances, within upholstery, and in voids. House mice may nest in ground burrows or debris outside.

House mice can be identified by a characteristic musky odor.

Mice nibble on food all day long. They eat many times and eat at different locations. However, they do have two main meal times, just before dusk and just before dawn. They can eat about 10 to 15% of their body weight every day, the adults weighing about 5/8-1 oz. Mice also cache food as supply permits. They get much of their water from food products.

Mice can be seen during the daylight hours but are active mostly at night.

A house mouse is an excellent climber and can run up any rough vertical surface. It will run horizontally along wire cables or ropes and can jump up 13 inches from the floor onto a flat surface.

House Mouse Inspection

Their droppings(feces)are rod shaped, about 1/8-1/4 inch long. House mice will gnaw making clean holes about 1-1/2 " in diameter. Mice will gnaw on paper and boxes, using it for nesting material. House mice will also gnaw on bar soaps.

Mouse tracks, mouse droppings and fresh gnawing show locations where mice have been active. Mice make nests out of shredded paper, cardboard or other fibrous materials. These mice nests may be found in sheltered locations.

Sanitation ,exclusion and reducing the mouse population is what is involved for rodent prevention and control.

House Mouse Exclusion and Prevention

A house mouse can squeeze through openings slightly larger than 1/4 inch across, eliminate all openings through which they can enter a structure.

House Mice Proofing Your House

  • Seal any openings larger than 1/4 inch to exclude mice.
  • House mice frequently find their way into homes in the fall of the year, when outdoor temperatures at night become colder.
  • Eliminate all openings through which mice can enter a structure. Seal openings and cracks around structure foundations. Seal openings around utilities, vents and pipes.
  • for the mouse not to chew or pull out patching compounds, the patching materials need to be smooth on the surface.
  • Doors, windows, and screens should fit tightly.
  • Mouse proof all stored, processed or used food. Store meat and grains in glass jars, resealable airtight containers or metal canisters.
