As part of its mosquito control plan, Nassau County is continuing its pesticide ground treatment in targeted areas, with the next spraying scheduled for Thursday from 7 p.m. to 2 a.m., weather permitting, health officials said.
Areas to be treated are sections of East Massapequa, North Massapequa, Massapequa, Massapequa Park, Lakeview, Lynbrook, North Lynbrook, Rockville Centre, Malverne, Malverne Oaks, South Hempstead and West Hempstead.
The chance of being sickened by the spraying of the pesticide Scourge is "quite low," the Nassau County Department of Health said in a statement.
Still, as with any pesticide, residents may want to avoid exposure, with children and pregnant women especially advised to stay indoors during the treatment and for about 30 minutes afterward, the release says.
Areas treated last night were sections of Old Westbury, Garden City, Albertson, Westbury, Salisbury, Carle Place, Williston Park, Roslyn Heights, East Garden City, East Williston and Mineola.
The rain date for Thursday's treatment is July 31.
Locations to be sprayed are chosen based on data such as the number and types of mosquitoes present, as well as their persistence, said Carolyn McCummings, a health department spokeswoman.
So far this year, West Nile virus has been detected in Nassau County in 10 mosquito samples from nine trap locations: those in Bayville, Bethpage, East Rockaway, Hicksville, Lakeview, the Massapequa Preserve, Mineola, Old Bethpage and Oyster Bay Cove, according to the health department.
People become infected with West Nile virus through the bite of an infected mosquito, which is why health officials also advise eliminating stagnant water around homes where mosquitoes breed.
Further ways to reduce exposure to the pesticide include closing windows and doors during and just after spraying; setting air conditioners to circulate indoor air; moving children's toys indoors, as well as pets and their food, water dishes and toys.
