The mouse species most frequently encountered in residential buildings is the house mouse (Mus musculus). It is also called the domestic mouse.
What are the mice that live in houses called? - in detail
The rodent most frequently encountered in domestic environments is the house mouse, scientifically designated Mus musculus. It belongs to the family Muridae and is a small, gray‑brown mammal with a body length of 6–10 cm, a tail of similar length, and a weight of 10–25 g. Its skull and dental formula (1/1 incisors, no canines, 0 premolars, 3 molars) distinguish it from other commensal rodents.
Mus musculus thrives in human habitations because it exploits readily available food sources, shelter in wall voids, and warmth from heating systems. The species exhibits rapid breeding cycles: a female can produce 5–10 litters per year, each containing 4–8 offspring, with gestation lasting roughly 19 days. This reproductive capacity explains the swift population growth observed in infested dwellings.
Key characteristics that aid identification include:
- Dark, hairless ears and whiskers that extend beyond the head.
- A pointed snout and a tail that tapers and is scarcely furred.
- Footpads that leave clean, crescent‑shaped tracks on dusty surfaces.
Health implications stem from the mouse’s role as a vector for pathogens such as Hantavirus, Salmonella, and Leptospira. Contamination occurs through droppings, urine, and gnawed materials, which can infiltrate food stores and ventilation systems.
Control measures rely on integrated pest management:
- Exclusion – sealing cracks larger than 1 mm, installing door sweeps, and repairing damaged screens.
- Sanitation – removing food residues, storing perishables in airtight containers, and maintaining regular waste disposal.
- Population reduction – employing snap traps, electronic devices, or approved rodenticides in accordance with safety regulations.
- Monitoring – placing bait stations or sticky traps to assess activity levels and guide intervention timing.
Alternative commensal rodents occasionally found in homes include the roof rat (Rattus rattus) and the Norway rat (Rattus norvegicus). These species differ in size, coloration, and preferred nesting sites; however, they share the same potential for structural damage and disease transmission.
Understanding the taxonomy, biology, and behavior of the domestic mouse provides the basis for effective identification and management, reducing health risks and property loss associated with infestations.
