House mouse (Mus musculus)

Small, unobtrusive, and highly adaptable, the house mouse (Mus musculus) can quickly become a significant nuisance. By entering buildings in search of warmth, water, and food, it causes damage, contaminates sensitive surfaces, and promotes an unhealthy environment. Taking action at the first signs is essential to sustainably protect your home or business.
