County to combat West Nile Virus
Mosquito Control Division will spray in Roosevelt

ROOSEVELT, NJThe Monmouth County Mosquito Control Division will be conducting a mosquito control operation to control flying adult mosquitoes on Thursday, Sept. 29 from 4:30 and 6:00 a.m. in the Borough of Roosevelt due to evidence of West Nile Virus in the area. The treatment area extends north from Brown Rd. to Oscar Dr. and west from Spruce Ln. and Eleanor Ln. to Pine Dr.

The County will be spraying “Duet Dual-Action” which contains two pesticides called Prallethrin and Sumithrin, and a synergistic compound called piperonyl butoxide which increases the effectiveness of the pesticides. The County will be using truck-mounted, ultra-low-volume equipment that applies the pesticide at a fraction of an ounce per acre.

“The County Mosquito Control Division is committed to limiting flying adult mosquitoes and any illness they may carry,” said Commissioner Deputy Director Susan M. Kiley. “We encourage residents to help control the mosquito population by eliminating sources where they can breed, such as removing any standing water around the home by emptying buckets of water and turning them over and drilling drainage holes in garbage and recycling cans.”

Pyrethroids have been recommended for Ultra-Low-Volume (ULV) mosquito control in New Jersey by Rutgers, The State University of New Jersey. The U.S. Environmental Protection Agency’s (EPA) current evaluation considers pyrethroid-containing products to be slightly toxic with minimal potential risk to people when used properly as part of an integrated mosquito control program.

“Some of the ways you can protect yourself and your loved ones is by using EPA registered repellents, wearing long sleeves and long pants and limiting outdoor activities at dusk, “said Deputy Director Kiley.

Residents can help ‘Fight the Bite’ by using the Mosquito Control checklist to find and eliminate all the places where mosquitos breed around your home. The checklist and information about a courtesy inspection can be found at
