Mouse Noises in the Walls

mice in wallsMice enter buildings in search of food sources, to escape predation, and to breed. Once inside, they enjoy making nests in secluded areas with sufficient warmth. For this reason, mice often take up residence inside the walls of buildings. The pests gain access to wall cavities via piping, air ducts, and external holes in structures. Since they are small creatures, mice are capable of slipping through holes less than a quarter of an inch in diameter. Since their populations grow rapidly once a nest is established, it’s important that homeowners remain alert for signs of mice in walls.

Signs of Mice in the Walls of a Home

Sounds and smells are helpful in determining if there are mice in the walls. Scurrying and scratching sounds will be common during the night. Homeowners may also hear squeaking coming from wall cavities. As a single mouse produces 50 to 75 droppings a day, excrement will quickly accumulate given an infestation. It won’t be long before the smell pervades the building. Additionally, mice give off a characteristic musky odor that helps with the detection of mice in walls. Finally, as their fur is greasy and dirty, mice often leave marks on wall exteriors as they scamper alongside floorboards.

Removal from Walls

Prompt removal of mice is important because of all the issues they cause. For one, the pests must constantly gnaw to control the growth of their teeth, and this behavior can lead to structural damage and even fire hazards when they target electrical wires. When mice die inside wall cavities, their bodies start to rot, which is odorous and attracts secondary pests like flies. Finally, mice carry a number of diseases that they spread to humans by urinating and defecating in food products. At the first sign of mice in the walls, homeowners should contact professional wildlife removal services to eliminate infestations.
