  • DNREC's Mosquito Control Section will start its annual spring woodland-pool spraying this week, treating wooded wetlands near select populated areas in New Castle, Kent and Sussex counties.
    Between 4,000 and 7,000 forested acres that produce large numbers of early season mosquitoes will be strategically sprayed to treat immature aquatic larval stages, using larvicides applied by helicopter and possibly fixed-wing aircraft.
    Aerial spraying of woodland pools must be completed before the forest canopy fills in with leaves, usually around mid-April, because leaves prevent the insecticide from reaching pools and other wet spots containing larvae on the forest floor.
    Over the next few weeks, Mosquito Control will apply a bacterially-produced insecticide, Bti. “Like all insecticides used by the Section, the U.S. Environmental Protection Agency has determined that Bti, when used in accordance with all EPA-approved instructions as required by federal law, can be applied without posing unreasonable risk to human health, wildlife or the environment,” said Mosquito Control administrator Dr. William Meredith.
