Mosquito spraying scheduled in Suffolk County this week

With an eye to mosquito control, Suffolk County has scheduled spraying in certain areas for Tuesday, Wednesday and Thursday, county health officials said Tuesday.

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

On Wednesday, too, ground spraying, also using Anvil, is scheduled for 6 p.m. to 10 p.m. for all streets in Ocean Bay Park, Ocean Beach and Seaview on Fire Island.

On Wednesday and Thursday, 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 the towns of Islip, Brookhaven, Southampton, East Hampton, Riverhead and Southold, officials said.

The pesticides VectoBac 12AS liquid concentrate and Altosid liquid larvicide concentrate are to be sprayed, weather permitting, over marsh areas 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 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. 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.
