Ground Spraying for West Nile Virus in Sections of Massapequa, Massapequa Park and North Massapequa Completed

Ground Spraying in the Merrick, Valley Stream and Wantagh Vicinities still on Schedule

Nassau County has completed the ground spraying for West Nile virus that was scheduled for Tuesday, August 3 in sections of Massapequa, Massapequa Park and North Massapequa.

Recent surveillance data has demonstrated an increased threat of West Nile virus. Experts from the New York State Department of Health have advised Nassau County that the risk to the public’s health warrants the application of adulticide to control mosquitoes in certain areas of the County. In an effort to control mosquitoes that may be carrying the West Nile virus, Nassau County will continue to ground spray those areas previous identified.   

Where: Areas to be sprayed by truck will include sections of the following communities:  Merrick, North Merrick, Freeport, Roosevelt, Valley Stream, North Valley Stream,

Franklin Square, Elmont, Wantagh, North Wantagh, Levittown, Seaford, and North Massapequa.  The ground spraying will be conducted within a one-mile radius of our mosquito surveillance trap.  The areas of detail are included in the attached maps.

When: Weather permitting, the planned schedule for truck spraying is as follows:

Sections of Merrick, North Merrick, Freeport and Roosevelt:  Wednesday, August 4th, 7 pm – 12 am.

Alternate dates: Thursday, Monday or Tuesday, August 5th, 9th or 10th, 7 pm – 12 am.

Sections of Valley Stream, North Valley Stream, Franklin Square and Elmont:  Thursday, August 5th, 7 pm – 12 am.

Alternate dates: Monday, Tuesday or Wednesday, August 9th, 10th or 11th, 7 pm – 12 am.

Sections of Wantagh, North Wantagh, Levittown, Seaford and North Massapequa:  Monday, August 9th, 7 pm – 12 am.

Alternate dates:  Tuesday, Wednesday or Thursday, August 10th, 11th or 12th, 7 pm – 12 am.

What: Scourge is a pesticide containing resmethrin and piperonyl butoxide. Resmethrin is a man-made pyrethroid insecticide that can also be found in other pesticide products used indoors and on pets to control ticks and other insects, such as fleas and ants. Piperonyl butoxide does not directly kill insects on its own, but acts to increase the ability of resmethrin to kill insects. These active ingredients are dissolved in a petroleum solvent.

Health Effects: The chance of experiencing any health effects from the use of Scourge to control mosquitoes is quite low. As with any pesticide, individuals may want to reduce or eliminate exposure. Some particularly sensitive individuals may possibly experience short-term effects such as eye, skin, nose or throat irritation or breathing problems.

To Reduce Exposure: The US Environmental Protection Agency (EPA) and the New York State Department of Environmental Conservation (DEC) do not require relocating or taking special precautions during mosquito control spraying. Individuals, especially pregnant women and children, should remain inside during the spraying and for about 30 minutes afterwards. In addition, individuals may minimize exposure by:

  • Keep windows and doors shut, setting air conditioners to re-circulate if able. Turn window fans off.
  • Keeping children's toys indoors.
  • Keeping pets indoors, as well as their food, water dishes and toys.
  • Cover fishponds during the spray period.

Since the effects of the ground spraying dissipate in a few hours, it is not necessary to wash off outdoor furniture or playground equipment before use, although doing so will not diminish the effectiveness of the pesticide applied.
