Most experts on mosquitoes and the viruses they harbor agree that spraying now is too late in the season. Superintendent of Plymouth County Mosquito Control Anthony Texeira admonishes the population in Massachusetts and adjacent states to be extra careful.
A horse died in Middleboro from eastern equine encephalitis (EEE) and on September 20, Middleboro was placed at critical risk levels for EEE. A ranking system for EEE has been established by the Massachusetts Department of Public Health using five levels: remote, low, moderate, high and critical “when risk has been determined to be excessive.”
Obviously, when the horse died and tests established EEE in Middleboro, the proof of EEE danger was confirmed. Mosquito control expert Texeira “believes the virus has been in town all summer even though it didn’t show up in any samples.” Neighboring towns of Lakeville, Plympton and others nearby will need to take special care as well, and realize their populations are at equal risk.
Standby planes to spread pesticide are now ineffective because it is too late in the season. Spraying on ground levels are equally out now. It is too cold at this time of year for any type of spraying because the mosquitoes do not fly when temperatures dip below 60 degrees.
At this late stage in the year, it becomes the exclusive responsibility of every individual to remain safe.
It doesn’t mean there isn’t any dangerous mosquitoes out there. Any mosquitoes left over from the summer are more deadly because they are probably infected with EEE.
Eastern equine encephalitis was originally discovered July 30 in Hanover. The threat of the virus stays effective until the first hard frost.
These are the towns that have had positive infected mosquitoes: Abington, Canton, Easton, Halifax, Hanson, Hingham, Kingston, Rockland, West Bridgewater, Whitman, Raynham and Quincy. Texeira believes the virus is likely present in Plympton, Lakeville and Middleboro.
