The answer to 'why is my mouse invasion' is that mice are drawn to homes in search of food, water, and shelter. Common causes include improperly stored food, cracks or holes in the home's exterior, and nesting materials like insulation or cardboard. Symptoms include droppings, gnaw marks, and sightings of the mice themselves.
To solve a mouse problem, start by sealing any entry points, removing food sources, and setting humane traps. However, if the infestation is severe or you're unable to fully eliminate the mice, it's best to call a professional pest control technician. They have the expertise and equipment to effectively and safely remove the mice and prevent future infestations.
