Mosquito Control Update

Mosquito Surveillance and Control in Pittsfield


This Spring and Summer, in the City of Pittsfield, the Berkshire County Mosquito Control Project (BCMCP) will be actively conducting mosquito control activities. By monitoring the larvae and adult mosquito population, BCMCP is able to confirm the presence of two mosquito borne viruses, West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE) and determine high-risk regions within the city.

In recent summers, WNV and EEE has been present in the mosquito population in the city of Pittsfield. These are viruses found in perching songbirds in freshwater swamps or urban environments. The virus is spread through a population of birds through the bite of a mosquito. These viruses can become more prevalent in an area through interactions between infected birds and infected mosquitoes. Species of mosquitoes that bite birds and mammals indiscriminately can transmit the virus from the bird population to humans and domestic animals.

Personal protection is the best defense against mosquito borne illness:

  • When outdoors, wear long pants, a long-sleeved shirt and socks.
  • Use a repellent with DEET according to the instructions on the product label
  • Keep mosquitoes out of your house by repairing holes in screens and making sure screens fit tightly to doors and windows
  • Schedule outdoor events to avoid the hours between dusk and dawn, when mosquitoes are most active

Remove areas of standing water around your home to eliminate sources of mosquito breeding

  • Mosquitoes can begin to multiply in any puddle or standing water that last for more than four days.
  • Change the water in birdbaths every few days
  • Turn over plastic wading pools and wheelbarrows when not in use
  • Clean clogged roof gutters, remove leaves and debris that may prevent drainage of rain water.
  • Remove standing water from pool covers
  • Look around outside your house for containers and other things that might collect water and turn them over, regularly empty them, or dispose of them.
