Plans Finalized for Mosquito Spraying in Pachaug State Forest

The State of Connecticut Mosquito Management Program will be spraying for mosquito control in areas of the Pachaug State Forest considered to be at high risk for Eastern Equine Encephalitis (EEE) virus and West Nile virus (WNV). The spraying will be conducted in Mt. Misery campground and the nearby Horse Camp also known as the Frog Hollow Horse Camp, and on roads from the main forest entrance to Hell Hollow Road. Spraying is scheduled to begin Monday, August 26, 2019 at 7:00 pm, weather permitting, and will continue overnight until completed. Roads will be closed to vehicular traffic during the spraying. The area to be sprayed is not a residential area and no precautions are needed for residents in surrounding areas.
This is an area where high concentrations of mosquitoes infected with EEE virus and WNV have been identified, including mosquito species known to bite humans.  EEE is a rare but potentially deadly disease in people and horses. WNV is found in Connecticut most summers and can cause severe disease in humans and horses.  Horse owners are reminded to review vaccination records with their veterinarians to ensure that EEE and WNV vaccinations are current and their horses are protected during the mosquito season.
The pesticide used is a product called Anvil which contains the active ingredient d-phenothrin, also called sumithrin. Sumithrin is similar to the natural compounds used in pesticide products used indoors including many common sprays for fleas and flying insects.
Spraying reduces risk of infection with EEE and WNV virus, but does not completely eliminate risk. People spending time in the area should continue to take precautions to prevent mosquito bites.
These include:
  • Minimize time outdoors at dusk and dawn.
  • Be sure door and window screens are tight fitting and in good repair.
  • Wear shoes, socks, long pants, and long-sleeved shirts. Clothing material should be tightly woven.
  • Use mosquito netting when sleeping outdoors.
  • Consider using mosquito repellent when it is necessary to be outdoors and always use them according to label instructions. The most effective repellents contain DEET or Picaridin. Oil of lemon eucalyptus is also effective for brief periods of exposure.
Connecticut Mosquito Management Program
The response to mosquito transmitted diseases in Connecticut is a collaborative inter-agency effort involving the Department of Energy and Environmental Protection (DEEP), the Connecticut Agricultural Experiment Station (CAES) the Department of Public Health (DPH), the Department of Agriculture and the Department of Pathobiology at the University of Connecticut (UCONN). These agencies are responsible for monitoring mosquito populations and the potential public health threat of mosquito-borne diseases.
