Suffolk County has scheduled ground spraying for Thursday, weather permitting, with an eye toward mosquito control, county health officials said Wednesday.

Spraying using the pesticide Anvil is planned for 6 to 10 p.m. for all streets in Fire Island Pines, Atlantique, Summer Club and Water Island on Fire Island.

Previously announced is spraying Wednesday from 6 to 10 p.m. for all streets in Ocean Bay Park, Ocean Beach and Seaview on Fire Island.

The chances of experiencing health effects from the ground spraying are “quite low,” the health department said, but children and pregnant women should avoid exposure by staying clear of the area during and at least 30 minutes after spraying.

Among the protective measures the department suggests are closing doors, windows and air-conditioning vents before spraying and keeping them closed 30 minutes afterward.

In addition to being annoying, some mosquitoes’ bites can transmit West Nile virus to people.

There’s also concern about the Zika virus, which can be transmitted through the bite of an infected Aedes aegypti mosquito, not yet found in New York State.

However, a related species, Aedes albopictus, also known as the Asian tiger, is active in the downstate region, Long Island included, and “may be able to effectively transmit the virus,” health officials said.
