In your home, they’ve been know to eat glue, soap and other things found around the house. To communicate with each other, mice will often squeak. They have great vision and hearing. Mice use their whiskers to feel their way around surfaces.

House Mouse Damage

These mice can ruin items you have laying around your house when they are seeking out places to nest. They can gnaw holes in woodwork, siding, sheetrock, insulation, packaging, furniture, and sometimes even copper pipes. These mice can further chew wiring, which may cause a fire or short-circuit electrical systems. Nests may also block vents, creating another potential area where fires may start. They can also dig up seeds in newly planted gardens when they are looking for food. It’s not uncommon for mice to eat human foods, either. Cereal and grain are some of their favorites, along with corn and seeds. When they feed on these items, they usually become contaminated. House mice can also carry lymphocytic choriomeningitis virus, a disease that can cause fever, lack of appetite, chest pain, and sore throat. This can last up to three weeks, but is not usually fatal.

Their droppings will be deposited in cabinets, drawers, sinks, or near food. The smell of urine may also be present. House mice nests are usually made of paper and shredded materials.
