The Montgomery County Health Department (MCHD), after consulting with the Pennsylvania Department of Environmental Protection (PADEP), Conshohocken Borough and Plymouth Township officials, will be adulticiding (spraying) to control the adult mosquito population in selected areas.

The spraying will be done where sampling by the Health Department and PADEP has shown mosquitoes that carry the West Nile Virus. The spraying will be conducted, weather permitting, on Wednesday, August 31, 2016 from approximately 8:15 p.m. to 11:30 p.m. The alternate date will be Wednesday, September 7, 2016.

All areas within the highlighted sections of the below maps will be subjected to spraying:

Conshohocken

Plymouth Township

Workers will be using Duet Duel-action Adulticide at a rate of .75 fluid ounces per acre applied with a truck mounted Ultra Low Volume (ULV) sprayer. The spraying will be performed by MCHD personnel. The Health Department will work with appropriate agencies to identify, eliminate, or treat with larvacide, areas where mosquitoes are breeding. Residents may contact the Health Department at 610- 278-5117 if they are concerned about an area of standing water that may be a breeding area.

The adult mosquito control program will only be used in limited situations to reduce large numbers of adult mosquitoes. For further information about the products being used, please visit the EPA website at: https://www.epa.gov/mosquitocontrol.
