Rodents can transmit disease to humans, pets, and livestock. They have been found to transmit typhus, leptospirosis, trichinosis, and salmonellosis. The presence of mice and rats is usually detected by the damage they cause to food and structures, by their droppings, and by their nests. Treatment involves eliminating all entry points and population reduction by the application of rodenticides and traps.
