Mice and Rats
Scientific Name: Rodentia
Rodents make up the most numerous group of mammals, with 2277 species, accounting for 41% of the known mammals. They have become serious pests in all phases of food supply and to human health due to these close encounters with the food we eat and the places we live and work.
Rodents carry a wide range of disease-causing organisms, including many species of bacteria, viruses, protozoa and helminths (worms). They also act as vectors or reservoirs for many diseases via their ectoparasites such as fleas, ticks, lice and mites, as well as some diseases carried by mosquitoes. In fact, rodents are thought to be responsible for more deaths than all the wars over the last 1,000 years.
