Mouse House mice are able to enter homes through openings in buildings as small as a quarter of an inch in diameter. They infest wall voids, basements, attics, barns, sheds, porches, and other places that provide them with shelter from the elements and adequate food. The pests also live in fields and on farms. Mouse Noises Mice use vocals to express emotions and relay the location of food and shelter. The noise they make most frequently is a high-pitched squeak, almost like a singing chatter, but it can change in pitch and frequency depending on what they're trying to communicate. For example, their squeaks are faster during mating and louder when they find food. House mice are also notorious for making scratching and scuffling noises as they move behind baseboards, drywall, and floorboards in homes. These sounds are caused by the pests' nails digging into surfaces for grip. Control & Removal In addition to being noisy, these pests cause a number of issues around homes. They spread diseases, such as leptospirosis and salmonella, and contaminate food. Mice also leave collections of their urine and droppings all over buildings. As such, individuals should contact pest control specialists at the first sign of infestation.
