Mice might look harmless, but they create serious problems for homeowners if left to their own devices. These tiny invaders carry big health risks that can affect your entire family:

Health Threats

Mice spread numerous diseases through their droppings, urine, saliva, and even the parasites they carry. Their feces can contaminate your food preparation areas with bacteria and viruses. When disturbed, dried mouse droppings can become airborne, allowing you to breathe in disease particles. They're also known carriers of hantavirus, salmonella, and leptospirosis — all serious conditions that can land you in the hospital.

For allergy and asthma sufferers, mice make their symptoms worse. Their dander, fur, and waste products trigger reactions and can make breathing difficult, especially for children. The protein in mouse urine is particularly allergenic and can persist in your home long after the mice are gone.

Property Damage

The damage mice cause goes way beyond the gross factor. These rodents have teeth that never stop growing, forcing them to chew constantly on whatever they can find. This habit leads to destroyed insulation in your attic, damaged wood in structural elements, and chewed furniture and belongings.

Most concerning is their tendency to gnaw on electrical wiring, which creates serious fire hazards in your walls and crawl space. Many house fires with "unknown causes" actually start with rodent damage to wiring. Mice can also damage water pipes, leading to leaks and water damage that opens the door to termite problems and mold growth.
