Mosquito Fish are NOT native to California so they should NOT be planted in Creeks, Streams, Lakes, Rivers, Vernal Pools or any other habitat where they will be in competition with sensitive native fish, aquatic organisms, or where other endangered species may be present.

The use of Mosquito Fish (Gambusia affinis) are a very effective method for controlling immature (larval) mosquitoes. An adult mosquito fish can consume as many as 500 mosquito larvae a day. Mosquito fish are an attractive biological control method used as an alternative to other chemical control methods in many environmentally sensitive areas.
