When temperatures drop, rodents head indoors. America's rodent problems peak in winter, but aren't restricted to a specific region, a recent survey by the National Pest Management Association
found. Each year nearly a third of all American households experience rodent problems, the survey revealed. Beyond the sheer 'ick factor' of discovering rodent droppings or hearing their scurrying sounds at night, Americans need to beware of the potential health and safety impact of a rodent infestation. Mice and rats carry a variety of diseases, and can cause property damage - even electrical fires if they chew through wiring.
