What is West Nile Virus?
It is a mild virus of birds that is transmitted by the common house mosquito,
which usually poses a threat to those over 40 years old. Fatalities are
rare, usually limited to those over age 60. Symptoms, if they appear, show
is 1-2 weeks. If the virus occurs, the threat is in late summer, NOT spring,
because the disease must build up in the bird population. Mosquitoes don't
carry West Nile Virus through the winter, and typical nuisance mosquitoes
don't carry West Nile Virus.
Morris County Response
We will monitor the mosquito population levels for the presence of the disease
(in mosquitoes and in birds). Control efforts will be intensified if the
disease shows up: the aquatic stage of the mosquito will be targeted first.
then the adult mosquito. We will coordinate with scientists at Rutgers
University, with the State Office of Mosquito Control Coordination, and
with Health Departments to watch for West Nile Virus.
What Homeowners Can Do?
Individuals can clean up containers that hold water around their yards. This
included buckets, birdbaths, tires, pool covers, wading pools, and gutters.
The house mosquito needs permanent, standing water to multiply.
Homeowners can reduce mosquitoes
on their property:
- Dispose of unwanted containers
that can hold water
- Store unused containers in
an upside-down position
- Empty or cover swimming or
wading pools when not in
- Change water in bird baths
and troughs weekly
- Keep roof gutters and drainage
ditches cleared out so water
does not collect and sit
- Properly grade and eliminate
any areas where water can
- Contact your local mosquito
agency for more information
related to reducing mosquito breeding
sites on your property
Individuals should protect
themselves from mosquito bites.
People should make sure their window
and door screening is in good repair
so that mosquitoes cannot enter
the room. When going outside during
the times when mosquitoes are most
likely to be biting (dawn or dusk),
wear protective clothing such as
long sleeved shirts and pants.
Mosquito repellant can be very
effective in preventing insect
bites. CAUTION: When using repellants,
always carefully read and follow
the manufacturer's directions on
You can make a difference
by removing these sources!
The Morris County Mosquito Commission
employs a modern, integrated approach
to mosquito control that meets
or exceeds the protocol of the
EPA Pesticide Environmental Stewardship
Program. The commission monitors
mosquito numbers and control these
insects only when necessary, using
water management, controlling the
aquatic stages of mosquitoes with
products specific to them, and
doing limited adult mosquito control
as a last resort. The Commission
has a staff of nine inspectors
who continually survey known mosquito
producing areas throughout the
County and implement appropriate
control measures when necessary.

Bottom Line We have a thorough,
efficient system in place to prevent
an outbreak of this disease and
to manage nuisance mosquitoes.
