CLIFFWOOD, Aberdeen — Monmouth County mosquito control crews will be out tonight trying to prevent the spread of the mosquito-borne West Nile Virus.

Crews will be conducting a ground spray on residential streets throughout the Cliffwood neighborhoods. So keep pets inside, close your windows and vents, and wash any garden fruits and vegetables as a precautionary measure, officials warned.

What are they doing, exactly? The application will be made using truck-mounted ultra-low volume equipment dispensing a very fine mist of the pesticides Duet or Zenivex. Duet is a d-phenothrin/prallethrin and piperonyl butoxide based pesticide product that is used to control mosquitoes in outdoor residential and recreational areas. Zenivex contains a pesticide called Etofenprox, a member of the category of pesticides called non-ester pyrethroids and is considered a reduced risk pesticide by federal Environmental Protection Agency.

Two people have died this summer from West Nile infections including a 57-year-old Monmouth County woman, according to an NJ.com report. The state did not identify her, but the Asbury Park Press reported she was from Wall.

Subsequently, Monmouth County crews began a mosquito control operation in Wall and Spring Lake Heights soon after her death. They are returning to Belmar, Spring Lake Heights and Wall Friday night.
