Rats are rodents that can spread disease, contaminate food and chew up property. Rats burrow in the ground, forming tunnels with one main opening and one or two exits. The 2- to 3-inch wide entrance hole is usually found under a covering like a low plant, mulch or debris. Before closing up burrows, the rats must be eliminated or they will just re-open the holes.
Food and warmth are the main attractions for rats. Eliminating food sources and sealing off entrances to warm homes and other structures can help to drive down rat populations. Rats can live on just an ounce of food and water each day, so when food is bountiful, they will make themselves at home. Rats are attracted to homes, businesses and restaurants, and they will feed from the trash if it is left uncovered or if they can gnaw through a receptacle to gain entrance. Signs that rats have invaded a home or business include gnawing and scurrying sounds in the attic or walls, as well as chewed spots, wood chips, wood shavings and tooth marks in baseboards, windows, doors, electrical cords or even packaged foods.
