The Central Massachusetts Mosquito Control Project (CMMCP) will begin enhanced larval treatment plans for Eastern Equine Encephalitis (EEE) mitigation, which will target a mosquito species of concern for EEE transmission to mammals via helicopter the week of May 23, 2022. This same program was used in the Shrewsbury community in May of 2020 and 2021.
Applications of the enhanced larval treatment are scheduled to begin Monday, May 23, 2022 and will run for two to three days in Shrewsbury. Total flight time over the town should be less than two hours. The exact application dates are uncertain at this time, as low winds and minimal rain are necessary for the applications to take place.
Please note that this is not a “wide area aerial application” that is part of the municipal opt-out program in place by the State Reclamation Board — that is only for aerial spraying of adult mosquitoes using an aerosol insecticide. The enhanced larval treatment taking place the week of May 23, 2022 is for applications of a certified organic, granular form of bacteria only over wetlands outlined on the map below.

In addition to Shrewsbury, the CMMCP will deploy enhanced larval treatment plans in Ashland, Grafton, Holliston, Hopedale, Hopkinton, Marlborough, Milford, Northborough, Northbridge, Southborough and Westborough.
