Rat Pests Are More Bold Around Humans Within Homes Than Many People Realize
Norway rats (Rattus norvegicus) and black rats (Rattus rattus) both originated from Asia before spreading into Europe, and eventually, North America. These two rat species were likely introduced into European ports by Asian ships during the middle ages when trade relations between the two continents became commonplace in the Mediterraenan sea. A few centuries later, it is believed that the Norway and black rat species made their way into the New World on colonial ships. This makes Philadelphia one of the first urban areas of North America to become inhabited by rats, and this is probably why rats remain overabundant pests in the city to this day. Although these two rat species likely shared living space on ships hundreds of years ago, Norway and black rat habitats do not overlap in the US. If these two rats wind up in the same geographic location, the Norway rat will always displace the black rat.
Black rats are often referred to as “roof rats” given their ability to climb trees and infest attics and the upper floors of homes and buildings. Norway rats are not as adept at climbing, and they generally invade homes from the ground. Black rats can be found in rural areas of Pennsylvania, but they are most abundant in the southernmost states. Norway rats are more cold hardy than black rats, and they are rarely found in rural areas; instead, Norway rats have adapted to dwell alongside humans within urban and suburban areas. In fact, Norway rats can survive more easily within human dwellings than they can in the natural environment. Unlike most wild animals, Norway rats show little fear around humans and they readily approach non-moving humans within homes. Much like dogs, the presence and even the scent of humans causes Norway rats to relax comfortably in human dwellings. During the colonization of North America, Norway rats settled new urban areas just as quickly as humans did. While rats rarely bite humans, most bites occur in homes while humans are sleeping, which makes sense considering the Norway rat’s habit of approaching motionless humans. Luckily, it is exceptionally rare for people to contract diseases via rat bites, but rats do contaminate 10 percent of the world’s food supply, which has led to Salmonella outbreaks in the past.
