Xerces Opposes Bandon Marsh Spraying

The Xerces Society urges the U.S. Fish and Wildlife Service not to spray Bandon Marsh NWR for the control of nuisance mosquitos because the treatment will harm wildlife, cause disruption to the refuge ecosystem and will likely not be an effective way to manage mosquitoes.

By Celeste Mazzacano and Scott Hoffman Black

Scientists at the Xerces Society for Invertebrate Conservation sent a letter on September 3, 2013 to the U.S. Fish and Wildlife Service asking that the agency abandon a proposed mosquito control project at the Bandon Marsh National Wildlife Refuge. Although no public health emergency had been declared, and no existence of mosquito-transmitted disease had been found, a decision was made to spray about 10,000 acres in and around the refuge with two insecticides, Dibrom and MetaLarv S-PT. Both of these insecticides are toxic to a broad variety of wildlife.
