How Wide Are Rat Holes?
WouterThe size of rat holes depends on various factors. These include the shape of the hole, its purchase, its height, and the substrate on which it is located. The size of the hole also varies with the age of the rat. Juvenile rats, for instance, fit through much smaller holes than adult rats.
Rat holes are typically between two and four inches wide. The rodents leave loose dirt outside their entrances. In addition, rat holes tend to be a few inches deeper than a regular hole. They also have multiple exits. In addition to a smooth entrance, rat holes have alternate exits, which they use to leave the abode.
Rats live in burrows underneath the ground, but sometimes they attempt to enter a building. For example, a rat may attempt to burrow into a building by digging a hole that is several inches deeper than the surface. Once inside, a rat may use the hole to breed and lay eggs. The deeper burrows are also often lined with insulation.
Rats can squeeze through holes as small as a quarter-inch in diameter. They can also dig deeper, a meter or more deep. Their burrows can extend as far as the foundation of the house. Aside from their burrows, rats also leave one or two exit holes to escape from predators. However, their exit holes tend to be more difficult to find than their main entrance. In addition, they are often concealed by other objects or dirt.
