Mosquito spraying in Fire Island, Suffolk marshes this week

Suffolk County has scheduled spraying — both ground and aerial — for mosquito control for Tuesday and Wednesday, county health officials said.

Ground spraying with the pesticide Anvil is planned from 6 to 10 p.m. Tuesday for all streets in the communities of Davis Park and Point O’Woods on Fire Island.

Also, on Tuesday and Wednesday, vector control is planning aerial spraying of certain salt marsh areas from 5 a.m. to 8 p.m. to target mosquito larvae in areas of all Suffolk towns but Smithtown, officials said.

The chances of experiencing health effects from the ground spraying are “quite low,” the county 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 “common-sense steps” the department suggests are closing doors, windows and air-conditioning vents during spraying and 30 minutes after.

The pesticides VectoBac 12AS liquid concentrate and Altosid liquid larvicide concentrate are to be sprayed, weather permitting, over marsh areas Tuesday and Wednesday by helicopter at low altitude, officials said.

County officials said residents don’t need to take precautions, any human exposure is unlikely and the pesticide has “no significant human toxicity.”

In addition to being annoying, some mosquitoes’ bites can transmit West Nile virus to humans. 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. That could include in 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.
