Rat infestations can quickly become a large issue if not properly identified and handled. The two most common types of rats found in homes, businesses and commercial buildings are the Norway Rat and the Roof Rat. Identified by their appearance and behaviors, each can be effectively eradicated with a DIY rat control program.
The Norway rat is usually brown or black with a yellow or gray belly. Average weight can be well over a pound, and the Norway rat can be 7” to 10” long with a broad set body. A Norway rat’s head is long, with a blunt nose and small ears that lay close to the head. Norway rats can also be identified by their tails, which are never as long as their bodies. Common foods for Norway rats are vegetables, fruits, meats and fish- essentially any human consumed food. Norway Rat droppings are blunt and about ¾ of an inch, and anywhere from 30-180 droppings are produced a day. The Norway rat prefers to nest in a basement or other lower dwellings. Known to burrow into soil, creating extensive runs, the Norway rat is typically active at night. Life expectancy of a Norway Rat is 18 months, and reproduction rates are typically 6-18 rats in a litter, and 3-7 litters in a year.
Probably the most common rat species, the Roof Rat is very territorial and will travel the same areas night after night. They can cover about 100-300 ft. in their run ways, and although typically nocturnal, rats are known to be active during the day if populations are getting large, or if they have become agitated. The Roof Rat has more of a long slender build, with large ears and longer, point nose. A Roof Rat is typically black, with a gray/white belly. The roof rat will nest in trees, ivy and ground cover, and the upper portions of buildings. They rarely burrow, are excellent climbers, and are very active at night. Rats can be suspicious of environment changes, and even if new foods are introduced. A few days may pass before baits, traps or poisons are effectively working.
