Franklin County: Mosquitos targeted for spraying


Mosquitos beware. Franklin County is out to get you.

The county will spray residential and recreational areas for adult mosquitos beginning around sunset (7:31 p.m.) Sept. 7. The target areas are in these communities:

  • Main Street, Fayetteville,
  • Ragged Edge Road,
  • Guilford Hills, and
  • surrounding communities

Tests detected high populations of adult mosquitoes capable of transmitting West Nile Virus in the above areas.

Weather conditions and other unexpected events could delay or cancel the spray operation. An alternative spraying date is Sept. 8.

The Pennsylvania Department of Environmental Protection’s Mosquito-Borne Disease Program conducts the truck-mounted ultra-low volume (ULV) mosquito control operation in Guilford and Greene townships.

Franklin County’s Mosquito and Tick Borne Disease Control specialist will be on site for the application.

Franklin County’s business license is BU 13939. The spraying operation uses Deltagard, applied at a rate of 0.75 oz/ac. This product provides quick knockdown and effective control of adult mosquitoes. 


Seven positive mosquito pools

Franklin County has had seven West Nile Virus-positive mosquito pools so far this year. Positive samples collected between Aug. 23-27 came from the following townships and boroughs:

  • Chambersburg Borough (one),
  • Hamilton Township (two),
  • Greene Township (two) and
  • Guilford Township (two).

Due to recent heavy rainfalls that have created mosquito larvae habitats, mosquito populations have a high likelihood of flourishing in the next few weeks. When this anticipated increase in mosquito population is mixed with evidence of West Nile Virus, the rate of positive West Nile Virus mosquitoes will most likely climb, continuing into the fall until the first frost.

Now more than ever, Franklin County residents should protect themselves from mosquito bites by wearing or implementing some form of repellent, including wearing long sleeves and pants when outside.

Residents and homeowners should watch for standing water, including artificial containers holding water such as buckets, clogged gutters or tarps. Mosquitoes can breed in something as small as a soda bottle cap filled with water.
