Most useful in catching Rats and Mice for Home, Bakery, Restaurants, Offices, Food Processing Industry, Hospital, Warehouses, Malls, Multiplexes, etc. Place rat traps in high-activity areas of the rat colony. These areas may include darkened corners, along walls, behind appliances and objects, and all areas where droppings are evident. Since rats need to touch surfaces as they move, place them accordingly. Place rat traps spaced from 15-20 feet apart. Remember to place them touching a wall since rats like to run along walls to avoid detection. Position rat traps to maximize the chances of rats to cross over the traps during their natural travels along their runways. If rat traps are set parallel to the wall, set them in pairs with triggers situated to intercept the rats from either direction. Do not touch pets, before handling the traps.
