Health Department to Spray for Mosquitoes in Sections of Sharon Hill on Monday, August 22

August 19, 2022

The Delaware County Health Department’s (DCHD) West Nile Virus Control program will conduct an Ultra-Low Volume (ULV) mosquito adulticide spray in sections of the Collingdale, Darby, Aldan, and Sharon Hill municipalities on Monday, August 22, 2022.

Residential and recreational areas within the treatment zone will be treated to control adult mosquitoes.

Treatment will take place during the evening of Monday, August 22, 2022, starting at approximately 8:00 pm and concluding by 12:00 am, if weather and environmental conditions remain suitable for the operation. In the event of weather or other unexpected delays, a rain date is scheduled for Wednesday, August 24, 2022.

The Delaware County Health Department will perform the treatment using truck-mounted spraying equipment. The product used will be Duet, applied at a rate of .75 ounces per acre, designed to provide quick and effective control of adult mosquitoes. For resident safety and information, the business license ‘BU3865’ will be visible on department equipment.
“This planned spray is the result of the identification of positive mosquito pools and a high vector index (VI) in the area,” said Delaware County Health Department Director, Melissa Lyon. “A vector index greater than 300 determines the planning of adulticide treatment sprays to address the presence of West Nile positive pools.”

For more information, including a map of the areas to be treated, please see the DCHD’s full press release.
