Mosquitofish

Seminole County has utilized mosquitofish (Gambusia holbrooki) in areas to prevent mosquito emergence and lessen the amount of pesticides used.

• Mosquitofish can eat their weight in mosquito larvae daily.
• It is native to Florida.
• Its temperature range is between 30-100F.
• Mosquitofish are extremely hardy and will tolerate and thrive in just about any standing water, regardless of pH or oxygen content.
• They bear live young, which are born approx. 3/8 " long and immediately feed on mosquito larvae.
• When stocked in ponds with larger fish they may inhabit the shallows to avoid predators.
• Mosquito larvae inhabit the shallows and become easy prey to the mosquitofish.

If you have an area that may benefit from mosquitofish, contact the Mosquito Control office.
