House mice enter buildings seeking warmth, shelter, and food, squeezing through gaps as small as 6mm in diameter. They nest in wall cavities, loft insulation, kitchen units, and undisturbed storage areas, using shredded paper, fabric, and insulation materials. Mice remain active year-round but increase their attempts to enter properties during autumn and winter when outdoor temperatures drop. Once inside, they establish complex networks of runways along walls and under floorboards, rarely venturing into open spaces.
London’s dense housing, older building stock, and abundant food sources create perfect conditions for mouse populations. Terraced properties particularly suffer as mice move freely between adjoining buildings through cavity walls and shared loft spaces. Commercial premises including restaurants, warehouses, and retail spaces face constant mouse pressure, with infestations threatening health ratings, stock damage, and business reputation. Without professional treatment, mouse populations continue growing until they cause significant damage and health risks.
Problems Caused by Mouse Infestations
Mouse infestations create serious health hazards beyond the unpleasantness of seeing rodents scurrying across floors. Mice contaminate food preparation surfaces and stored food with urine, droppings, and fur carrying harmful bacteria. A single mouse produces 50-80 droppings daily, spreading contamination throughout properties as they explore.
