The Norway rat is common in Las Vegas. It’s easily identifiable due to its large size and aggressive nature. The pest can grow to be nearly 9 inches in length or up to 18 inches including the tail! The Norway rat has coarse dark brown fur that is lighter on the belly.
The roof rat is several inches smaller than the Norway rat and has black, shiny fur. The ears are large and mostly hairless, and they have pointy noses. The tail of the rat is usually longer than its body. The roof rat is also nocturnal and tends to burrow for shelter.
Las Vegas is also home to field mice and house mice. Both rodents are much smaller than the two rats found in the area but can still cause problems for residents. Their smaller size, speed, and climbing abilities make it easy for these mice to find access to homes.
The Most Common Rodents in Las Vegas
- Norway Rat. This rat is very destructive. It is a large at, weighing up to one pound, and is considerably long compared to other rats. These rats are scavengers and are attracted to cluttered areas and love garbage. Although there are not a lot of problems with this type of rat in the Las Vegas area, they still have been seen on occasion. These rats can breed very quickly, so when one is seen, action should be taken to exterminate the rodent.
- Roof Rats. The Roof Rat first appeared in the Las Vegas Valley area around 1990. It is believed that they made it to the area on imported palm trees. These rats are small and have a much longer tail in comparison to a Norway Rat, but are still very destructive. Roof Rats are more prone to eating natural foods like fruits, vegetables, seeds and nuts, but they have been known to dig through garbage when food is scarce. Roof Rats have been a large problem in the Las Vegas area because they breed rapidly. Each female rat can have eight babies each litter, and can have up to six litters a year.
- Field Mice. These small mice live in the fields or on farms where they can easily access vegetation to eat. Field mice, however, are omnivores and will eat meat or anything else they determine is safe to eat. Field mice are known to burrow into the ground to get to a food source. Field mice have litters of babies that can easily exceed 14 each time. Stopping the population is necessary because offspring can start reproducing within 8 weeks of birth.
