How Common Are Rats in Your Home?
WouterMany studies have found that in the United States, there is one rat for every person. This ratio is similar to that of many other countries. A 1909 study in the United Kingdom also found a similar ratio, although the results have been periodically disputed. There are 56 species of rats, and most do not live in areas that are populated by humans. However, if food and shelter are available, rats will breed year round.
Rats can enter homes through holes in the walls or floors. Once inside, they will begin making holes, typically two to three inches wide and a few inches off the ground. They also leave behind an unpleasant odor. If you suspect rats are present in your home, the first step is to thoroughly clean any visible evidence of their presence.
Rats are nocturnal animals and usually leave their nests at dusk. They are remarkably smart, able to chew through barriers and find food quickly. As a result, they can survive in large numbers without the human knowledge. These animals can cause damage to buildings and spread diseases. In London, many residents are terrified of rats in their homes.
There are many types of rats. The largest ones live in the rural parts of Africa and are around 20 to 35 inches long. They live in large groups and can be aggressive. Their diet is extensive and includes almost everything, including livestock and humans. Another type of rat you may encounter is the Norway rat, which is aggressive and tolerant of cold climates. Norway rats are 12 to 18 inches long and weigh up to 16 pounds. They have small eyes, naked ears, and coarse fur.
