How Many Mosquitofish do I Need to Control Mosquitoes on my Property?

And where do I get them?

Mosquitofish are used throughout the world as an efficient, hearty predator of mosquitoes, and for good reason. They are biologically suited for feeding on insects that fall onto or reside at the water’s surface. Their mouths, set upon an angular, tilted jaw, seem designed to slurp the mosquito larvae from their respite like spaghetti.

It’s the perfect marriage: mosquito larvae must reside at the water’s surface because they need to breathe air. They live below the water’s surface, filtering and scooping microscopic nutrients into their mouths at a flurry’s pace. But, eventually, they must float to the water’s surface and place their siphon tube through it and into the oxygenated air. Since mosquitofish feed at the water’s surface, mosquito larvae are easy prey.

How many mosquitofish do I get from you to control mosquitoes in my water sources?

Mosquitofish are extremely proficient at eating mosquitoes. Each one, when full grown (about two inches) can eat up to 500 mosquitoes per day.

We recommend one fish per four square feet of surface water (not volume). Because mosquitoes hang out at the surface of the water, the volume of water is of no consequence to how many fish are needed to control them.

Where do I get mosquitofish? Are they free?

Yes. They are free from our District. Just stop by our office during business hours and we’ll help you determine how many you need for your specific water source. If you need more than 50 mosquitofish, please call us ahead of your arrival and we’ll have them bagged and ready for you.

Mosquitofish can be used in neglected swimming pools (capable of producing more than 1 million mosquitoes and affecting people up to five miles away), ponds (they cohabitate with other fish), water collection barrels, large fountains, and more.
