Request for Gambusia affins “Mosquito Fish”

We are happy to provide you with Gambusia affinis.  In certain situations, this mosquito eating fish is a valuable resource in reducing mosquito populations in approved water habitats. 

Gambusia affinis is not an indigenous (native) species to the State of Washington.  To insure that this fish stays only in approved habitats, we need to inform you of the importance of not transporting or distributing Gambusia affinis yourself.   Franklin County Mosquito Control District has been approved by the Washington State Department of Fish and Wildlife (WDFW) to use Gambusia affinis as a biological control method for mosquito larvae.  We, therefore inspect potential habitats before we transport any Gambusia affinis.  It is illegal for any one not authorized by the WDFW to transport, distribute or introduce Gambusia affinis into any water habitat.

Please read and complete this form, acknowledging you understand that approval from the WDFW is required for transport.  Upon receiving this form, we will process your request and evaluate your water habitat to see if it is suitable for Gambusia affinis transport.  Gambusia affinis can survive through the winter under certain conditions.  But, if you have to drain your water habitat or don’t feel the fish will survive, we will come and retrieve them if so desired.
