Mice and rats are a problem when they find their way indoors. They like to be near humans so that they have a ready supply of food. This has earned them the term "commensal," which means "to share one's table."
The class of creatures called "rodents" actually encompasses much more than just mice and rats. It refers to any animal whose incisor teeth continue to grow, so they must continually gnaw in order to keep them serviceable.
There are more than 2,200 different rodents. Together they make up more than 40% of all mammals. In this group you will find: mice, rats, squirrels, capybaras, nutria, chipmunks, prairie dogs, and many more.
Rodents can carry up to thirty-five diseases that humans are susceptible to, which is another reason to set up pest prevention as soon as possible. Cleaning up after a rodent infestation also requires a great deal of caution. This is necessary because of the possibility of fleas, which may transmit their own diseases.. There is also risk involved if you inadvertently stir up the dust of their nests; it can be hazardous to breathe in the bacteria contained within.
Rodents can also do physical property damage. They easily chew through some types of siding and other building materials. They are also known to chew on electrical lines, thereby increasing the possibility of fire. They damage other materials as well, creating holes and gnawing on numerous objects, especially food or food containers.
