Mosquito Spraying Wednesday Evening July 18, 2018

Wednesday  Evening July 18, 2018

The Cumberland County Vector Control Program will be conducting an ultra-low volume (ULV) mosquito control operation to reduce high populations of mosquitoes capable of transmitting West Nile Virus disease in PARTS of:

Camp Hill

E. Pennsboro

MAP of the spray route will be available Tuesday at 3pm on the County Webpage:

Alternate spray date will be the next evening, weather permitting

Weather conditions and other unexpected events could delay or cancel this spray operation.

If conditions do not allow application on the scheduled date, the following evening will serve as the back-up spray date.

The treatments will be administered via truck-mounted equipment, spraying residential and recreational mosquito habitat.

The equipment dispenses DeltaGuard ULV at a rate of .95 ounces per acre. Treatment time starts near to or at dusk.

The product is designed to provide quick, effective control of adult mosquito populations. The application material has a very

low toxicity profile to mammals and is applied during hours that it will have negligible impact to non-target insects.

Certain mosquito species carry Mosquito-borne Disease including West Nile Virus, which can cause humans to contract West Nile encephalitis,

an infection that can result in an inflammation of the brain. According to the Pennsylvania Department of Health, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis.

Individuals can take a number of precautionary measures around their homes to help eliminate mosquito-breeding areas, including:

  • Dispose of cans, buckets, plastic containers, ceramic pots or similar containers that hold water.
  • Properly dispose of discarded tires that can collect water. Stagnant water is where most mosquitoes breed.
  • Drill holes in the bottom of outdoor recycling containers.
  • Have clogged roof gutters cleaned every year as the leaves from surrounding trees have a tendency to plug drains.
  • Turn over plastic wading pools when not in use.
  • Turn over wheelbarrows and don’t let water stagnate in birdbaths.
  • Aerate ornamental pools or stock them with fish.
  • Clean and chlorinate swimming pools not in use and remove any water that may collect on pool covers.
  • If a resident has stagnant pools of water on their property, they can buy BTI products at lawn and garden,
  • outdoor supply, home improvement and other stores. This naturally occurring bacterium kills mosquito larvae,
  • but is safe for people, pets, aquatic life and plants.
