Another Round Of Delco Mosquito Spraying On The Way

Delaware County is planning to spray more areas in an effort to control the adult mosquito population and limit the potential spread of West Nile Virus and other mosquito-borne illnesses in the county, according to an announcement Monday.

County officials said areas in Upper Chichester, Lower Chichester, Marcus Hook, and Trainer boroughs will be sprayed with an ultra-low volume, low toxicity mosquito treatment the evening of Thursday, Aug. 24.

In the event of inclement weather, the spraying will occur Monday, Aug. 28.

The planned spraying will be the fifth time areas in the county have been hit with the insecticide, which is designed to provide quick, effective control of adult mosquito populations.

The chemical has a very low toxicity profile to mammals and is safe for the environment, officials said.

Certain mosquito species carry the 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 Centers for Disease Control and Prevention, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis.

The county offered up tips to residents to help limit mosquito populations on their properties:

  • Dispose of cans, buckets, plastic containers, ceramic pots or similar containers that hold water on your property.
  • 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.
  • Clean clogged roof gutters every year, particularly if the leaves from surrounding trees tend 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.
  • For stagnant pools of water, homeowners can buy Bti products
    at lawn and garden, outdoor supply, home improvement and other stores.
    This naturally occurring bacteria kills mosquito larva, but is safe for
    people, pets, aquatic life and plants.

Not only did the county provide tips to limit mosquito numbers, it offered tips to avoid mosquito bites:

  • Make sure screens fit tightly over doors and windows to keep mosquitoes out of homes.
  • Consider wearing long-sleeved shirts, long pants and socks
    when outdoors, particularly when mosquitoes are most active at dawn and
    dusk, or in areas known for having large numbers of mosquitoes.

  • When possible, reduce outdoor exposure at dawn and dusk during peak mosquito periods, usually April through October.
  • Use insect repellants according to the manufacturer’s
    instructions. An effective repellant will contain DEET, picaridin or
    lemon eucalyptus oil. Consult with a pediatrician or family physician
    for questions about the use of repellant on children, as repellant is
    not recommended for children under the age of two months.
