Mice in walls — Haarlem, Noord-Holland

Scratching and scurrying sounds inside walls, especially at night, are a clear sign that mice have found entry points into your home. Mice chew through electrical wiring, contaminate stored food, and leave droppings that pose health risks. Over-the-counter traps catch a few individuals but rarely stop the infestation. A pest-control technician performs a thorough inspection, identifies entry holes, sets professional-grade traps or bait stations throughout the affected areas, and seals gaps with steel wool and caulk to prevent reinfestation.
