The Montgomery County Office of Public Health (OPH), after consulting with the Pennsylvania Department of Environmental Protection (PADEP) and Whitemarsh Township officials, will be adulticiding (spraying) in Whitemarsh to control the adult mosquito population.
The area to be sprayed will be where sampling by the OPH and PADEP revealed mosquitoes carrying the West Nile Virus (WNV).
The spray event will occur on Tuesday, August 27th from approximately 8:00 p.m. to 11:00 p.m. If there is a weather issue, the alternate date will be Thursday, August 29th. All areas within the highlighted sections of the above map will be subjected to the spray.
According to the notice, all residents within the spray area should consider remaining indoors, closing windows and turning off ventilation systems that draw-in outside air for the duration of the spray plus 30 minutes after.
Workers will be using Duet™ dual-action adulticide at a rate of .75 fluid ounces per acre applied with an ATV mounted ultra-low volume (ULV) sprayer. The spray will be performed by OPH personnel.
The OPH will work with appropriate agencies to identify, eliminate and/or treat with larvacide, areas where mosquitoes are breeding. Residents may contact the OPH at 610-278-5117 if they are concerned about an area of standing water that may be breeding mosquitoes. The adult mosquito control program will only be used in limited situations to reduce disease-infected adult mosquitoes.
