Do mosquito control programs spray over the beach?
Pesticides labeled for use in Florida (by the Environmental Protection Agency) to control adult mosquitoes are not to be applied to open water, such as bays and lagoons. Aircraft may release sprays over water to drift over the land when wind speed and direction is sufficient to carry the spray to land. In controlling mosquito larvae however, the spray (larvicide) is often directly to the flooded salt marshes and other wetlands. These sprays are formulated to control mosquitoes without adversely affecting other organisms.
