8/13/2019: The MA Department of Public Health has provided the following update: The first round of aerial spraying for mosquitoes in areas of southeastern Massachusetts has been successfully completed as of Sunday, August 11. It remains critically important for people in communities at critical, high and moderate risk for EEE to continue to take personal precautions against mosquito bites. These steps include using EPA-approved bug spray, wearing long sleeves and pants outdoors to reduce exposed skin, and cancelling outdoor activities in the hours from dusk to dawn when mosquitoes are most active.

To achieve maximal effectiveness, a second round of aerial spraying will take place in the coming weeks in the southeast region. Follow-up mosquito testing data will determine which communities will be in the second spray zone. Please check back here for further updates as those plans are finalized.

8/9/2019: UPDATE: Aerial mosquito control spraying is scheduled to occur between approximately 8 p.m. and 4:00 a.m. Friday, August 9 and continuing the next several nights. Aerial spraying is weather-dependent and evening spray plans and zones are not finalized until late in the day and these plans are subject to change.

8/7/2019:  The Massachusetts Department of Public Health (DPH) and the Massachusetts Department of Agricultural Resources (MDAR) announced Tuesday, August 6, 2019 that aerial spraying for mosquitoes will take place in specific areas of southeastern Massachusetts. So far this year, 22 communities in southeastern Massachusetts have been found by DPH to be at high risk for the Eastern Equine Encephalitis (EEE) virus. Easton’s risk level is high.

EEE is a rare but serious and potentially fatal disease that can affect people of all ages. No human cases of EEE have been detected so far this year. MDAR will conduct and monitor aerial spraying in specific areas of Bristol and Plymouth counties which are anticipated to begin on Thursday, August 8, and continue over several evenings. The ability to spray is weather dependent and may change. Not every community in Bristol and Plymouth County will be sprayed. Easton is partially in the spray zone.  We are encouraging residents to visit DPH’s website (http://www.mass.gov/guides/aerial-mosquito-control-summer-2019) for the latest updates on spraying.  

Aerial spraying is conducted by airplane in areas of concern during early evening and nighttime hours.  There are no health risks expected during or after spraying. No special precautions are recommended, however, residents can reduce exposure by staying indoors during spraying. 

It is important to note; the aerial spraying will not eliminate the human risk.  Residents must continue to protect themselves from mosquito bites by staying indoors during peak mosquito hours, applying insect repellant when outdoors, draining standing water where mosquitoes breed, repairing screens in doors and windows and protecting pets.

Late  Season Advice:   As we move into the later part of mosquito season, mosquito populations are decreasing but older mosquitoes are also more likely to carry virus. With  cooler overnight temperatures, mosquito surveillance is less effective and the small numbers of mosquitoes that are actually trapped are not indicative of actual risk.  It is particularly critical at this time of year to use mosquito repellent and use clothing to reduce exposed skin. In areas at higher risk for EEE, schedule outdoor activity to avoid the dusk to dawn period as this is when mosquitoes most likely to carry EEE are most active. The risk for mosquito borne illness will continue until a hard frost.
