The answer to 'why is my mouse health risk' is that mice can carry and spread diseases that are harmful to humans, such as hantavirus, salmonella, and leptospirosis. Mice can also contaminate food and surfaces with their droppings, urine, and hair, which can cause health problems if ingested or inhaled. Additionally, mice can cause structural damage to homes by chewing on wires, insulation, and other materials, which can create fire hazards.
If you suspect you have a mouse problem, it's important to address it quickly to prevent the spread of diseases and further damage to your home. You can try DIY methods like setting traps or using repellents, but for a serious infestation, it's best to call a professional pest control technician who can safely and effectively remove the mice and prevent them from returning.
