Signs You Might Have a Rodent Infestation
Rats and mice prefer to stay out of sight, but they leave clues. Common signs include:
Scratching, scurrying, or light tapping in walls, ceilings, or under floors, especially when the house is quiet at night.
Droppings along baseboards, in pantries, under sinks, behind appliances, inside cabinets, or in garages and storage areas.
Dark rub marks or greasy smudges on walls, pipes, rafters, or beams where rodents run the same paths over and over.
Gnaw marks on food packaging, cardboard boxes, baseboards, cabinets, wires, plastic containers, or flexible water and drain lines.
Little piles of shredded paper, insulation, fabric, or dried plant material tucked into corners or behind stored items as nesting material.
A musky or ammonia like odor that lingers in enclosed spaces such as closets, attics, crawlspaces, or utility rooms.
Pets staring at a particular spot on a wall or ceiling, or pawing at an appliance or cabinet for no obvious reason, responding to sounds or smells you may not notice.
