Suffolk County has scheduled ground spraying for Tuesday and Wednesday, with an eye to mosquito control, county health officials said.

Ground spraying using the pesticide Anvil is planned for Wednesday from 6 to 10 p.m. for all streets in the Fire Island communities of Ocean Bay Park, Ocean Beach and Seaview.

Also Wednesday from 7 to 11 p.m., some streets in Brookhaven Hamlet are to be treated with the pesticide Duet.

As previously reported, ground spraying, also using Anvil, is scheduled for Tuesday from 6 to 10 p.m. for all streets in Davis Park and Point O’Woods 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 if possible by staying clear of the area during spraying and at least 30 minutes after.

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

In addition to being annoying, some mosquitoes’ bites can transmit West Nile virus to people. This year, there is also a concern about Zika virus, which can be transmitted by a certain type of mosquito that has not been found on Long Island.

Health officials say residents can help make areas around their homes unfriendly to mosquitoes by:

  • Regularly looking for and eliminating even the smallest amounts of standing water, which is where the insects reproduce, including cans, buckets and other containers, as well as old tires, tarps, pool covers and children’s toys.
  • Drilling drainage holes at the bottom of garbage cans, changing birdbath water at least weekly and making sure roof gutters are unclogged and draining properly.
  • Adding fish to circulate water in any backyard ponds, and clearing pond edges of debris and vegetation.
