Definition

noun

A method of controlling rodent pest population, such as by chemical, biological, or other means


Supplement

Some species of rodents are considered as pests because they are perceived as destructive, noxious, or disease-causing animals. Voles, for instance, are known for causing significant losses to crops. Some rodents are also vectors of certain diseases. The black rat, for example, may be infested with fleas carrying the bacterium Yersinia pestis (the causative agent of bubonic plague). Apart from this, the rodents are also carriers of several other diseases such as leishmaniasis, babesiosis, relapsing fever, Lyme disease, etc.

There are different ways to control rodent pests. Traditional methods include chemical poisoning and trapping methods. Another is by biological control. Biological control is a method of controlling a group of organisms (e.g. pests) with another set of organisms (e.g. natural predators of the former). Biological control may makes use of parasitism, predation, or herbivory. In this case, some of the predators of rodents are cats, ferrets, monitor lizards, and mongooses. Aside from predation, another biological control means is by introducing pathogens, e.g. Salmonella. However, this pathogen may also infect other hots, such as humans and domesticated animals.
