The Norfolk County Mosquito Control District (NCMCD) is planning to conduct an application of a granular mosquito larvicide by helicopter on one day, anticipated between September 20 and 23, 2021, weather-permitting. The aerial application will target wetland areas within Dedham, as shown in the map below, to treat the areas for Cattail Mosquito (Coquilletidia perturbans). (Click on the map image to enlarge):

NOTE: The exact date of aerial application will be posted on the NCMCD website.

What Will the NCMCD Spray:

The product used in this application is VectoLex FG, a bacterial larvicide (bacillus sphaericus) on a granular corn cob base.  It is not a liquid spray and it is non-toxic to people and pets. It is only toxic to mosquito larvae. 

What to Expect:

The NCMCD will utilize low-flying helicopters to ensure accurate application to the areas highlighted in green on the map above. The helicopters will need to get quite low to the surface, approximately 100 to 150 feet above the ground, and may turn around near or directly over homes. The operation will last less than one hour in Dedham.

Homeowners in the area of the application were notified of this upcoming spraying in a letter mailed to them by the NCMCD. (Download a PDF copy of the letter).
