Answer

Answer

A rat may gain entry into the home through a hole as small as 3/4 and a mouse as small as 1/4 of an inch. All openings, including pipe entries should be sealed or covered with metal mesh to prevent entry and openings under doors minimized. Debris and clutter located near the building should be removed to avoid masking evidence of rodent entry and as a potential rodent shelter. A non-vegetative border is recommended around the building perimeter to prevent the rodent from going undetected during movement from the outside to the inside of the building. [96]

Elimination of food and water supply

Food sources, such as cereal, grain, and pet food should be stored in sealed containers. Garbage should be removed from the building on a regular basis.

Use of rodent predators

Cats, owls, and snakes are rodent predators. A cat in the home may deter a mouse from entering the dwelling and reduce the mouse population. However, having a cat fails to completely eliminate a mouse population and is not a significant rat deterrent. One study indicates that 84% of subjects who were sensitized to mouse are also sensitized to cat so this intervention could cause more harm from the cat versus rodent sensitization. [96]

Rodent traps

Three main types of rodent traps exist: snap traps, live traps, and glue boards. The rodent triggers the snap traps. A pea-size amount of bait is placed on the trap and the trap placed along the perimeter of the room. Live traps use a baited cage with a one-way door to capture the rodent. Glue boards can be used to capture rodents and also droppings and hair. [96]
