The Delaware County Health Department’s (DCHD) Mosquito-Borne Disease Control Program will conduct an Ultra-Low Volume (ULV) mosquito adulticide spray in sections of Upper Darby Township, Lansdowne Borough, Yeadon Borough and Darby Borough on 8/1/24. Residential and recreational areas within the treatment zone will be treated to control adult mosquitoes. This is a result of high trap counts and the identification of positive mosquito pools containing West Nile Virus in the area.

Treatment will take place during the evening of 8/1/24, starting at approximately 8:00 pm and concluding by 11:00 pm 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 8/5/24.

In Yeadon Borough, the area to be sprayed is mainly concentrated around Holy Cross Cemetery, as shown in the map below and on page 2 of the press release.
