Tomorrow, Wednesday August 19, 2015, the city will spray a pesticide in Bay Ridge and other neighborhoods to the east, along Gravesend Bay, to kill mosquitoes and thus limit human exposure to the West Nile virus. This year, the virus has not yet been detected in Bay Ridge, but it was already found in Dyker Heights, Bensonhurst and several other Brooklyn neighborhoods.
Spraying will begin as early as 8:30pm and end by 6am (Thursday). “For these sprayings, the Health Department will use a very low concentration of Anvil 10+10, a synthetic pesticide,” according to the city. “When properly used, this product poses no significant risks to human health.”
Still, that says nothing about the bees. And, anyway, officials recommend limiting direct exposure by staying inside, closing your air conditioner’s vent, moving toys and clothing indoors, and washing any clothing, skin or produce that may have been exposed.
Some people are more skeptical of Anvil 10+10’s efficacy and safety; a rundown of the counterargument to spraying can be read here. Additional resources are available at the No Spray Coalition’s website.
