The Norwood Board of Health reviewed a notice from the Norfolk County Mosquito Control District that the district may conduct helicopter applications of biorational larvicides targeting mosquito larvae in larger wetland areas between April 1 and Oct. 31.

The notice listed targeted spring and summer wetland locations across multiple communities and said applications would be weather-dependent. The towns named in the packet included Avon, Bellingham, Canton, Dedham, Dover, Foxborough, Franklin, Holbrook, Medfield, Needham, Norfolk, Norwood, Quincy, Randolph, Sharon, Stoughton, Walpole, Westwood, Weymouth, Wrentham and others.

The board was told that applications are restricted to wetlands and are usually performed early in the morning; they are not described as residential aerial spraying. The notice advised residents to check the district’s website for location details and scheduling; the meeting packet printed a web address provided by the district.

Ending: Board members said the district normally announces operations and that helicopters are commonly visible during application days; the board recorded the notice for the public record.
