The answer to 'why is my mouse damage' is that mice are common household pests that can cause significant damage to homes. Mice are attracted to homes in search of food, water, and shelter, and they will chew through walls, insulation, wires, and other materials to build nests and access food sources. Common signs of mouse damage include droppings, gnaw marks, and nests made from shredded materials.
To address mouse damage, it's important to first identify and eliminate the source of the problem. This may involve sealing entry points, removing food sources, and setting traps or using other humane control methods. If the infestation is severe or you are unable to effectively control the mice on your own, it's best to call a professional pest control technician who can assess the situation and recommend the most appropriate solution.
