The answer to 'why is my mouse property damage' is that mice can cause significant damage to homes through their gnawing and nesting behaviors. Mice have continuously growing teeth, so they need to constantly chew on materials to wear down their teeth. This leads them to damage insulation, wiring, furniture, and other household items as they search for food and build their nests.
Mice can also contaminate food sources and spread diseases like salmonella and hantavirus through their droppings. It's important to address a mouse infestation promptly to prevent further property damage and health risks.
