County will conduct mosquito control
operation in Freehold Township on Sept. 19

FREEHOLD TOWNSHIP, NJ – The Monmouth County Mosquito Control Division will conduct a mosquito control operation to control flying adult mosquitoes on Tuesday, Sept. 19, from 5 a.m. to 6:30 a.m. in Freehold Township, weather permitting, due to evidence of West Nile Virus in the area.

The treatment area is east of Pittenger Pond Road/Nomoco Road/Georgia Road extending to Geisler Road and Risa Benjamin Way, and north from the North Branch Metedeconk River extending to Quail Lane and Brandon Boulevard (see attached map).

The Mosquito Control Division 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 Division will be using truck-mounted, ultra-low-volume application equipment that applies the pesticide at a fraction of an ounce per acre.

“We are asking residents to pay attention to notices about sprayings found in the local media outlets as well as planning to limit outdoor activities during time of possible treatment. We also recommend moving your pets, their food and their water dishes indoors during application and to bring clothing and children’s toys indoors.,” said Commissioner Susan M. Kiley, liaison to the Monmouth County Health Department and Mosquito Control. “Some of the ways you can protect yourself and your loved ones from mosquito borne illnesses is by using EPA registered repellents, wearing long sleeves and long pants and limiting outdoor activities at dusk.”

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

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.
