Start by removing food and water sources, storing pantry items in sealed containers and keeping rubbish bins closed. Seal gaps around doors, pipes, roofs and walls, and use suitable snap traps in areas inaccessible to children and pets. Rodent baits can harm pets and native wildlife, so follow the label carefully and consider professional advice before using them. If rodents keep returning, or you find droppings in food areas, contact a licensed pest controller for an inspection and treatment plan.
