Mosquito Trapping and Surveillance Season Begins in

Nassau County for West Nile Virus

Uniondale, NY—The Nassau County Departments of Health and Public Works have begun mosquito surveillance and control activities for West Nile Virus. The Departments continue to work together to help control the spread of mosquito-borne diseases.

The Health Department conducts mosquito surveillance. This includes trapping and collection of adult mosquitoes which began May 3, 2010 at 42 sites throughout Nassau County. Additional surveillance activities include: identifying species; determining population distribution and abundance; separating and sending selected mosquitoes for viral testing; and thoroughly investigating all cases of suspect or confirmed encephalitis, including West Nile virus, to determine the source of infection.

The Department of Pubic Works (DPW) provides mosquito control. This includes monitoring and treating with larvicides, when appropriate, thousands of street basins, sumps, ponds and hundreds of miles of fresh water streams; checking suspect breeding sites for the presence of larvae; and maintaining “ditches” on the county’s south shore which allow fish to reach and consume mosquito eggs, larvae and pupae. DPW will continue aerial applications of larvicide in the non-populated areas in the south shore salt marshes as needed to control populations of salt marsh mosquitoes.

Nassau County residents are urged to take the following precautions to prevent mosquito breeding:

  • Remove or empty standing water from children’s outdoor toys, flower pots, garbage cans, pails, old tires, or any object that can hold water.
  • Make sure roof gutters drain properly; clean clogged gutters in the spring and fall.
  • Keep swimming pools chlorinated and their covers free of stagnant water.
  • Change the water in birdbaths every two or three days.
  • Install window and door screens and keep them in good repair.
  • Consider wearing long sleeves, pants, socks and mosquito repellent (according to directions) when outdoors when mosquitoes are active, especially in the late afternoon and from dusk to dawn.

For mosquito problems, stagnant water or a drainage problem, call the Nassau County Department of Public Works at (516) 572-1166, weekdays from 7:45 am to 3:30 pm.
