NORWAY RATS ​are believed to be of Asian origin, but are now found throughout the world. These rats can cause damage to properties and structures through their gnawing.  Norway rats have smaller eyes and ears and shorter tails.  They are primarily nocturnal and often enter a home in the fall when outside food sources become scarce.  These rats are known to gnaw through almost anything, including plastic or lead pipes, to obtain food or water.  Norway rats are social rodents and build burrows close to one another.

ROOF RATSalso called black rats or ship rats, are smaller than Norway rats, but cause similar issues.  This rodent gets its name from its tendency to be found in the upper parts of buildings.  The roof rat is thought to be of Southeast Asian origin, but is now found throughout the world, especially in tropical regions.  They are primarily nocturnal.  They forage for food in groups of up to ten and tend to return to the same food source time after time.  These rats follow the same pathway between their nest and food.

HOUSE MOUSE ​is the most common rodent pest in most parts of the world.  It can breed rapidly and adapt quickly to changing conditions.  In fact, a female house mouse can give birth to a half dozen babies every three weeks, and can produce up to 35 young per year.  House mice prefer to eat seeds and insects, but will eat many kinds of food.  They are excellent climbers and can jump up to a foot high, however, they are color blind and cannot see clearly beyond six inches.  House mice live in structures, but they can survive outdoors, too. House mice prefer to nest in dark, secluded areas and often build nests out of paper products, cotton, packing materials, wall insulation and fabric.
