Benton County, Broward County Plan Aerial Mosquito Spraying

Benton County Mosquito Control in Washington will conduct aerial insecticide spraying on May 6, 2025, targeting areas around the Yakima River, Richland, West Richland, and Prosser in response to high adult mosquito populations. The spraying, scheduled from 8 to 10 p.m., uses the chemical Naled, which breaks down within hours and poses minimal long-term environmental risk. Residents are advised to stay indoors during application, and while horses are expected to be safe if under cover, it is recommended to limit exposure for other animals and humans. Similarly, Broward County in Florida will initiate larvicide spraying between May 5 and May 10, 2025, in several cities including Hollywood, Miramar, Pembroke Park, and West Park, to combat mosquitoes capable of spreading diseases like dengue and chikungunya. The larvicide, VectoBac WDG, contains a naturally occurring bacterial ingredient that is not harmful to humans, pets, bees, or aquatic habitats and is approved by multiple health organizations. Both counties encourage residents to eliminate standing water to help reduce mosquito breeding.
