Aerial and truck-mounted spraying to control mosquitoes began Tuesday of this week, as communities in Plymouth County continued to register in the moderate to high risk levels for Eastern Equine Encephalitis, or EEE, according to information from the Massachusetts Dept. of Agricultural Resources.
Three towns in Plymouth County are at the critical level, according to a risk map from Mass.gov -Arbovirus. The five stages of risk are Remote, Low, Moderate, High, and Critical. Plympton, Halifax, and Kingston are all rated at Moderate risk, meaning that some mosquitoes sampled in these towns have been found to carry the Eastern Equine Encephalitis (EEE) virus. High risk would mean that animals have been found to be infected with the EEE virus, and a Critical designation means a human has been infected. Middleborough, Carver, and Plymouth have all been designated as High, as of Tuesday, Aug. 27. Four towns in southern Worcester County have been deemed Critical, due to a human case of EEE in Uxbridge.
The Plymouth County Mosquito Control project initiated aerial spraying in towns deemed Critical, beginning Tuesday, weather permitting. It will continue its truck-mounted spraying program, including spraying yards by request throughout Plymouth County. To see a list of the street-by-street itinerary for each town, go to https://www.plymouthmosquito.org/spray-routes-for-adult-mosquito-control.html. The spray routes will be posted at 3 p.m. for the following day. They list only the streets they expect to be on and not exact addresses. PCMCP honors all pesticide exclusion requests.
Residents can call up to eight times per season to be sprayed barring any spray restrictions in the area. The spray used will kill the mosquitoes in the area at the time that they spray and is not a preventative. Residents must make a request each time they have a mosquito problem, including name, address, phone number and email address. A confirmation email stating that PCMCP will come the requested property the next morning and a confirmation email on the day that spraying was done. Spray request phone calls are answered Monday – Friday from 7 a.m. to 2:30 p.m. at PCMCP phone: (781) 585-5450 and Fax: (781) 582-1276.
Pesticide applications are made via an ultra-low volume sprayer that is on the back of a pickup truck. Typically spraying is done from the street and can travel up to 300 feet. Weather permitting, the sprayers are operating from 2 a.m. to ½ hour before sunrise each weekday.
There is no cure for the EEE virus and the best treatment is prevention, according to the Mass. Dept. of Public Health.
