Vector Control

Vector Control works to decrease potential disease vectors, including mosquitoes and rats, both of which spread disease and are a nuisance. The program also responds to reports of other potential disease vectors.


Common Vectors

A vector is an organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another.


Mosquitoes can carry diseases which threaten the public health, including West Nile virus, and several forms of encephalitis. Learn more about mosquitoes, West Nile, and preventing bites.


Bats pose a threat to safety because if they bite a human or companion animal (i.e., dog or cat), there is the possibility of disease transmission, such as rabies. Learn more about bats and rabies.


Ticks are commonly found in Missouri and can carry various tickborne illnesses. Learn more about preventing tick bites, how to remove a tick, and symptons of tickborn illness
