Mosquito Spray Notice

In compliance with section 9.10 and 9.15 of the New Jersey Pesticide Control Code (N.J.A.C. Title 7, Chapter 30), the Middlesex County Mosquito Commission may be applying insecticides for the control of adult mosquito populations on an area-wide basis, as needed, throughout Middlesex County during the period of May 1st, 2020 through October 31st, 2020. In order to reduce the number of nuisance and vector mosquitoes in the specified area(s), the following adult mosquito control products will be applied from the ground by truck or handheld equipment and/or by aircraft, all using low volume (LV) or ultra-low volume (ULV) techniques.
Malathion​ (Fyfanon® ULV, ​Atrapa®, MicroFloMalathion®​ EPA Reg#67760-34) (Fact Sheet​)
Etofenprox (Zenivex® E4 RTU or E20, requiring dilution EPA Reg#2724-807) (Fact Sheet) 
Prallethrin - Sumithrin (Duet™ Dual-Action Adulticide​ EPA Reg#1021-1795-8329) (Fact Sheet​)
Deltamethrin (DeltaGard® ​EPA Reg#432-1534) (Fact Sheet)

The US Environmental Protection Agency (USEPA) & Rutgers University has approved and recommended these mosquito control products for residential mosquito control and considers them to pose no unreasonable health risk when applied according to label directions.  The Commission has notified municipal officials, health officers and police of these plans.  Neither the USEPA nor the NJ Department of Environmental Protection (NJDEP) requires relocating or taking special precautions during spraying with this product. All applications will be made according to product labeling.
Residents can take following precautions to reduce exposure:
  • Pay attention to notices about mosquito insecticide treatments found through newspapers, websites, automated telephone messages or notices distributed by municipal, county or state agencies. 
  • Plan your activities to limit time spent outside during times of possible insecticide treatments. Move your pets, their food, and water dishes inside during ULV applications. Also bring clothing and children’s toys inside. Stay back from application equipment, whether in use or not. 
  • Whenever possible, remain indoors with windows closed and with window air conditioners on non-vent (closed to the outside air) and window fans turned off during spraying. 
  • Avoid direct contact with surfaces that are still wet from pesticide spraying.  Do not allow children to play in areas that have been sprayed until they have completely dried (approximately one hour). 
  • If you must remain outdoors, avoid eye and skin contact with the spray.  If you get spray in your eyes or on your skin, immediately flush and rinse with water.
If residents wish further information, they can contact their local health department or call the National Pesticide Information Center at 1-800-858-7378 or visit their website at the following link:
