PROVIDENCE - The Town of Westerly, as it has done on a routine basis each year since 1997, will apply granules of mosquito larvicide by helicopter to 500 acres of swamp to control mosquito breeding. The targeted areas are portions of Chapman Swamp and the swamp area adjacent to Hespar Drive. The town is notifying adjacent landowners of its intent, as well as the general public, that it plans to apply the larvicide on Thursday, April 24, between 8 a.m. and 2 p.m. The larvicide may also be applied on future dates after notification by the town. April 25 and 28 have been designated as the rain dates.
The Department of Environmental Management approved the town's application to apply the larvicide Bti for mosquito control to the targeted areas.
Bti is a naturally occurring bacterium, which is applied in granular form to swamps and other mosquito breeding habitats to prevent larval mosquitoes from developing into adults. It is extremely safe from both an environmental and human health standpoint. Larviciding by communities is recommended as part of the state's action plan for West Nile Virus and Eastern Equine Encephalitis (EEE), and is the best way for communities to reduce mosquito numbers and risk.
