ATTENTION: Mosquito Tested Positive for EEE in Middlefield — PSHD Encourages Residents to take Precautions


The State of Connecticut has announced that a mosquito trapped in Middlefield has tested positive for Eastern Equine Encephalitis (EEE).  The Plainville Southington Health District (PSHD) encourages residents to protect themselves and their children by taking personal precautions to prevent mosquito bites when outside from dusk to dawn, when mosquitoes are most active.

“The mosquito that tested positive was located at the Durham Meadow test station in Middlefield which borders Durham”, according to Edward Bailey, the First Selectman of Middlefield. “Citizens of Middlefield, Rockfall, Durham and all our surrounding Towns should follow the personal protective measures recommended by our Health District to prevent EEE”.

“Residents should remain vigilant in taking personal precautions against mosquitoes,” said Shane Lockwood, PSHD Director of Health.  “EEE is rare, but if contracted can be serious.”

Mosquitoes remain active until the first heavy frost.  With the warm temperatures lasting into next week, residents are encouraged to take precautions.  Precautions include:

  • Avoid outdoor activities between dusk and dawn.
  • If outdoors, wear shoes, socks, long pants, and long-sleeved shirts. Clothing material should be tightly woven.
  • Use mosquito netting on baby strollers.
  • Use mosquito netting if sleeping outdoors.
  • Consider using mosquito repellent when it is necessary to be outdoors and always use them according to label instructions.

Additional measures residents can take around the home include:

  • Be sure door and window screens are tight fitting and in good repair.
  • Dispose of water-holding containers, such as ceramic pots, used tires, and tire swings.
  • Drill holes in the bottom of containers such as those used for recycling.
  • Clean clogged gutters.
  • Change water in bird baths on a weekly basis.
  • Clean and chlorinate swimming pools, and cover pools when not in use.
  • Use landscaping to eliminate areas where water can collect on your property.
