Rat Hole
Rats can fit in
tight spaces
Rats leave dirt, waste and grease in their paths. They are also capable of chewing through wood and concrete. Rat holes are both unsightly and dangerous: not only do they allow entry to a variety of pests, but they also compromise the structural integrity of the building. Rat holes may eventually lead to short-circuit fires and decay within walls and floors.
Locating rat holes may prove more difficult than expected. Holes in the floor should be sought, with particular attention being paid to locations where bricks, wood or tile may have rotted. Rat holes may exist between floorboards or in unlikely places, such as closets. Cluttered areas tend to attract rodents, as well as places surrounding water pipes. Rats may also use gas pipe entry holes behind stoves.
Sealing all possible entry points may prevent a rat infestation from taking place within your home. In the event of an existing rat population, plugging holes caused by these rodents may be one step in an effective extermination plan. Holes should be sealed with wire mesh made from copper, aluminum or stainless steel. The spacing of the mesh should be no greater than 1/4-inch. Chicken wire may also prove effective. For holes smaller than one inch in diameter, a clean, metal pot scrubber can be used. After stuffing, holes should then be covered with cement.
