Chewed wiring from rodents is a frustrating surprise when you lift the hood or open an appliance. The tiny teeth marks and exposed copper inside rubber insulation mean expensive repairs, possible short circuits, or even fire hazards. Usually happening in attics, garages, or behind walls, it often smells faintly of urine. You find it by noticing flickering lights, dead outlets, or a strange burning smell. Sealing entry points and setting traps helps prevent the damage.
