Vector Control’s Mission is to detect and minimize vector-borne diseases, to abate mosquitoes, and to assist the public in resolving problems with rodents, wildlife, and insects of medical significance.

What’s a vector?

A vector can be a mosquito, a rat, a flea, a tick, any animal or insect that can transmit disease or cause harm to humans.
