People don't live in the marshes wildlife does. Now you know why we have a problem with our shellfish dying off including lobster larva.
Suffolk County planned low-altitude helicopter treatments over marsh areas this week to control mosquito larvae, with applications scheduled from June 2 through June 4 between 7 a.m. and 6 p.m.
The Suffolk County Department of Public Worksβ Division of Vector Control said the work would use a granular pellet application of VectoPrime FG, a larvicide containing Bti, or Bacillus thuringiensis israelensis, and Altosid, also known as methoprene. The product is listed under EPA registration number 73049-501.
The treatments were planned for marshes across several Suffolk towns, including parts of Babylon, Islip, Brookhaven, Southampton, East Hampton, Riverhead and Southold. If weather prevented the work from being completed during the scheduled window, the county said it would continue on the next suitable day.
