Mosquitofish

Mosquitofish (Gambusia affinis) are small (1-2 inch) freshwater fish that are an effective and natural method of mosquito control. They can eat hundreds of mosquito larvae each day, which helps prevent mosquito bites and mosquito-borne illnesses.

Use them in artificial bodies of water such as: backyard ponds, birdbaths, fountains, animal troughs, unused swimming pools, etc.

Mosquitofish should never  be placed in a natural habitat  such as lakes, streams, rivers, or creeks as they may compete with native species. 

Female mosquitoes lay their eggs in standing water sources. The eggs hatch into larvae that grow into biting adult mosquitoes in 7 days or less. 

Adult female mosquitoes bite humans and animals and can spread diseases such as West Nile virus, Zika, Dengue, and yellow fever. Controlling mosquito larvae limits the number of adult mosquitoes and lessens the chance of getting bit by mosquitoes that spread diseases.

Let your mosquitofish get used to their new home. Keep them in their container and place it directly into the pond for 15 minutes. Wait until the pond and the container's water reach the same temperature. Then release the fish into the pond. After that, mosquitofish need little to no care.

Keep chlorine, garden insect sprays, and yard chemicals out of their water.
