House mice are small rodents that typically measure about two and a half to four inches long, not including the tail. Adults usually weigh less than an ounce. Their fur ranges from brown to gray, and their tails are roughly as long as their bodies.
House mice have relatively large ears, small dark eyes, and a pointed snout. Their small size and slender build can help distinguish them from young rats.

House mice can be active throughout the year in Tampa Bay, with no pronounced seasonal peak. Mice living indoors have access to relatively stable temperatures, food, and shelter, so activity can continue in any month.
House mice are primarily nocturnal, with most feeding and movement taking place after dark. They prefer grains and seeds but will eat a wide variety of foods.
Around homes, mice may feed on cereal, pantry goods, crumbs, pet food, birdseed, and other readily available food. They typically eat small amounts during multiple feeding periods rather than consuming one large meal.
House mice occur throughout Florida, including the Tampa Bay area.
House mice often live outdoors in fields and other protected areas but can move into homes, garages, storage buildings, and other structures where food and shelter are available. Once indoors, they tend to remain fairly close to their nesting and feeding areas.
House mice can contaminate food, stored items, and surfaces with urine, droppings, and nesting material.
They are associated with illnesses including salmonellosis and lymphocytic choriomeningitis, or LCM. Mouse allergens can also contribute to allergy and asthma symptoms in susceptible people.
Mice can also carry parasites such as fleas and mites.
Droppings and contaminated nesting materials should be handled carefully rather than swept or vacuumed while dry.
House mice gnaw frequently to help wear down their continuously growing teeth. In homes and buildings, this can result in damage to food packaging, stored belongings, insulation, drywall, and other materials.
They may also chew the protective covering around electrical wiring. Damaged wiring can create electrical problems and, in some situations, increase the risk of fire.
Mice also shred paper, fabric, insulation, and similar materials when building nests.
House mice can fit through openings about a quarter inch wide—roughly the width of the end of a pencil.
Potential entry points include gaps:
Once inside, mice may move through wall voids, cabinets, attics, garages, and other concealed spaces.
House mice choose sheltered nesting locations that provide protection and convenient access to food.
Indoors, nests may be found:
Their nests are commonly made from shredded paper, fabric, insulation, and other soft materials.
You are often more likely to find evidence of mice than see the rodents themselves.
Common signs include:
Droppings are often found near feeding, nesting, or travel areas, including cabinets, drawers, garages, storage areas, and along walls.
Individual traps can catch mice, but successful control also depends on finding and correcting the conditions that allow them inside.
If openings remain accessible, additional mice can enter even after the mice already inside have been removed. Hidden nesting locations can also make it difficult to determine how much activity is present.
Professional rodent control from Anti-Pesto starts with evaluating where rodents are active and how they may be getting into the structure.
Depending on the conditions at the home, rodent service may include trapping, exclusion work to help close accessible entry points, exterior rodent stations where appropriate, and follow-up service. For homes where rodent activity has damaged or contaminated attic insulation, attic restoration and insulation services are also available.
For homeowners who want broader, ongoing pest protection, Anti-Pesto's residential pest control plans include rodent trapping along with coverage for other common household pests.
Reducing potential entry points, food, and shelter can make a property less inviting to mice.
If you've found droppings, heard movement after dark, or noticed other signs of rodents, contact Anti-Pesto to request an inspection and determine what is active in your home.
