Aerial Mosquito Treatment near PHL to Control Threat of West Nile Virus
NORRISTOWN, Pa., June 1 /PRNewswire-USNewswire/ -- The Department of
Environmental Protection announced today that it will conduct aerial
spraying to control large populations of mosquito larvae in Philadelphia on
Monday, June 4.
The treatments -- VectoLex CG, which is not a chemical pesticide, but
is a species-specific bacterial agent that targets mosquito and black fly
larvae when added to the water in production areas -- will only be applied
in areas where sampling has shown increased levels of mosquitoes.
"The target areas are large mosquito habitats for the species that
potentially carry the West Nile virus," DEP Southeast Regional Director
Joseph A. Feola said. "We think we can do a better job of eliminating
mosquito larvae through aerial spraying than through traditional ground
Beginning around 8 a.m. Monday, Helicopter Applicators Inc., of
Gettysburg, Adams County, will spray VectoLex CG over wetlands in and
around the biosolid and wastewater treatment plants operated by
Philadelphia near Penrose Ferry Road in the southwest portion of the city.
They also will treat wetlands on the east side of the Philadelphia
Later in the morning, the applicator will spray wetlands at the city's
northeast wastewater treatment plant near the Betsy Ross Bridge.
Certain species of mosquitoes carry West Nile virus, which, when
transmitted to people, can cause 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 getting West Nile encephalitis.
There have been no confirmed human cases of West Nile virus in
Pennsylvania this year.
Individuals can take a number of measures around the home to help
eliminate mosquito-breeding areas, including:
-- Dispose of tin cans, plastic containers, ceramic pots or similar water-
holding containers that have collected on your property.
-- Pay attention to discarded tires. Stagnant water in tires is where most
-- Drill holes in the bottom of recycling containers left outdoors.
-- Have clogged roof gutters cleaned every year, particularly if the
leaves from surrounding trees have a tendency to plug the drains. Roof
gutters can produce millions of mosquitoes each season.
-- 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. A swimming pool left untended for a month
can produce enough mosquitoes to result in neighborhood-wide
complaints. Mosquitoes may even breed in the water that collects on
-- For stagnant pools of water, homeowners can buy Bti products at lawn
and garden, outdoor supply, home improvement centers and other stores.
This naturally-occurring bacteria kills mosquito larvae, but is safe
for people, pets, aquatic life and plants.
