is committed to using natural control methods to reduce reliance on
pesticide spraying for mosquitoes. We've implemented an aggressive fish
management program by stocking Gambusia holbrooki, aka "mosquito fish,"
in artificial impoundments, ditches, ornamental ponds, borrow pits and
stormwater retention ponds, and other places where mosquitoes breed.
This tiny fish devours mosquito larvae, reducing the numbers of adult mosquitoes. Gambusia holbrooki are considered native to this region and are commonly found in tidal areas and streams. They are related to guppies, and like guppies they bear live young. They are a hardy fish able to tolerate winter, over-crowding, and poor water quality.
