NORRISTOWN PA – Insecticide sprayings to control adult mosquito populations that may carry the West Nile virus are scheduled to occur during night-time hours Wednesday (Aug. 30, 2017) in selected areas of Royersford, Limerick and Upper Providence, and Thursday (Aug. 31) in Pottstown, the Montgomery County Health Department said in two separate announcements.
Both events are planned to occur between 8 and 11 p.m., weather permitting. 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.
Spraying will be done where samples taken by the health department and state Department of Environmental Protection indicate the presence of mosquitoes that carry the virus. The work will be performed by county personnel. The county said it had consulted with officials in all local municipalities involved before its announcements.
Alternate spray dates have been set for Sept. 6 and 7 (Wednesday and Thursday), respectively, in case of inclement weather.
Its adult mosquito control program is being used only in limited situations to reduce large numbers of adult mosquitoes, the county said. The health department added it will work with appropriate agencies to identify, eliminate, or treat areas where mosquitoes are breeding. Residents can call the department at 610-278-5117 if they are concerned about an area of standing water that may be a mosquito breeding area, it added.
