The house mouse is the rodent most likely to be living inside your home rather than outside it. Adults are small, typically 2.5 to 3.75 inches in body length with a tail of roughly equal length, and are covered in short fur that ranges from light brown to dusty gray, usually with a lighter, but not sharply white, belly. Their tails are thin, mostly hairless, and uniformly colored rather than bicolored like a deer mouse’s. House mice have relatively large ears, small dark eyes, and a pointed nose, and they can squeeze through openings as small as a dime.
House mice are extremely well-adapted to living alongside people, and in Los Angeles and Orange County homes they’re commonly found in kitchens, pantries, garages, and wall voids, as well as behind appliances and inside cluttered storage areas. They build nests from shredded paper, fabric, and insulation, often tucked into wall cavities, cabinet gaps, or boxes in seldom-used closets, and they tend to stay close to a reliable food source rather than ranging far like roof rats do outdoors.
House mice can cause meaningful damage by gnawing through wiring, drywall, and packaging, and they reproduce quickly, so small populations can grow into larger ones in a short amount of time. Their droppings and urine can contaminate food, countertops, and pantry items, and nesting inside walls or appliances can create ongoing sanitation concerns. Because they’re active mostly at night, a home infestation is often first noticed through droppings, gnaw marks, or scratching sounds rather than an actual sighting.
