Mice are difficult to control, and they present a serious menace to your home. Here’s what you should know about these pests: Mice are instinctively wary of traps and bait, and colonize in attics, burrows, under concrete and porches, in wall voids and other hard to reach places. Rats can harbor and transmit a number of serious diseases. They can also introduce disease-carrying parasites such as fleas, lice and ticks into your home. Mice can invade your home seeking food, water and warmth. One pair of mice can produce 200 offspring in four months. Each mouse can contaminate ten times more food than it eats.
