Central Mass. Mosquito Control Program:
"Water levels in the fall, throughout the winter and into the spring can dictate larval survival for Culiseta melanura, the species of mosquito that circulates EEE virus in the bird populations. This mosquito species spends the winter in diapause (a type of hibernation) in several larval stages, and will begin to emerge as adults in early to mid-May. Bird migration patterns from the south play an important role; as EEE is identified up the East Coast, that can give an indication for potential EEE exposures in Mass."

The Massachusetts Department of Public Health will soon be providing an updated fact sheet on EEE, this fact sheet will be shared on our website and other social media outlets as soon as it is made available.
