Rescheduled: Mosquito Spraying for West Nile Virus in Lower Moreland Township

Mosquito Spray Area for Lower Moreland on 9.1.21

NORRISTOWN, PA – The Montgomery County Office of Public Health (OPH) has announced the mosquito adulticiding (spraying) planned for tonight has been rescheduled to Thursday, September 2, 2021 due to weather.

The spraying will be done where sampling has shown mosquitoes that carry the West Nile Virus (WNV). For notification of any future spray events, sign up with the County's emergency notification system, ReadyMontco.

The spray event will occur, weather permitting, on Thursday, September 2, 2021, from approximately 8 p.m. to 10 p.m. All areas within the highlighted section of the map shown will be subjected to the spray. Spraying will occur in the area along Countyline Road and Byberry Road between Huntingdon Pike and Buck Road. 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 afterward.

Workers will be using a Duet® Dual-Action Adulticide at a rate of .75 fluid ounces per acre applied with a truck 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 larvicide, areas where mosquitoes are breeding. Residents may contact the OPH at 610.278.5117, if there is an area of standing water of concern that may be breeding mosquitoes. The adult mosquito program will only be used in limited situations to reduce disease-infected adult mosquitoes.

For further information about the products being used, visit the OPH website.
