Summer 2001 Mosquito Prevention
This is the time of year when mosquoitoes are out in force,
and may spread diseases, including West Nile virus. It's a good idea to
police your yard for standing water that can provide a breeding ground.
Remove or turn over vessels that hold water, including wheelbarrows, unused
pots and trays beneath containers. Flush out bird baths regularly.
Mosquitoes can breed in unlikely locations – a bottle
cap filled with water, leaf debris or clogged rain gutters, discarded
tires. Clear clogged gutters, which can hold water. Treat ponds with Bt
drinks, which kill mosquito larvae without hamming desired aquatic life,
including fish. A thorough clean up will help lower the risk of being
bitten by a mosquito.

Summer 2001 Update & Precautions
Beginning Monday, June 18, 2001 Oneida County Health Department
staff began setting CDC light traps and Gravid traps for mosquitoes in
several locations throughout Oneida County. Pools of mosquitoes captured
in these traps were submitted to Albany to be tested for the presence
of West Nile Virus. Results will be made available as they are received
by the Health Department.
Larval surveillance has also been performed in areas near stagnant water.
This will allow Health Department officials to determine the presence
of particular mosquito species that may play a role in the transmission
of West Nile Virus.Health Department staff, in conjunction with other
agencies as appropriate, are investigating potential mosquito breeding
habitats noted last summer and those reported thus far this season to
the Health Department. Several areas have been investigated, and as the
weather warms up, will be inspected again for mosquito larvae.
The Health Department is continuing to send dead birds to the New York
State Department of Health for testing. No positive tests from Oneida
County have been reported yet. Bird submissions and results are shown
in the following table.
West Nile Virus is transmitted by particular species of mosquito. Property
owners can minimize the risk to themselves and their neighbors by finding
and eliminating sites where mosquitoes breed. This does not just apply
to businesses and homeowners who live near water.
As the warm weather continues, mosquitoes will become more prevalent.
It is important to take clean-up action now to curb the spread of West
Nile Virus as much as possible.
The Oneida County Health Department requests the assistance of the public
in reporting potential breeding sites due to standing water that residents
see on public lands or on abandoned properties. Contact the Health Department
at 798-5064.
Dead crows or jays could be a sign of West Nile Virus, but it is important
to remember that West Nile Virus has killed not all dead birds. Contact
the Oneida County Health Department at 798-5064 to report dead crows and
jays. Not all birds can or should be picked up for testing.

About Mosquitoes and Your Yard
Mosquitoes are small flying insects that feed on human and
animal blood or plant juices. Only female mosquitoes bite to get a blood
meal for their growing eggs. Mosquitoes are generally considered a nuisance
pest, but occasionally can transmit disease.
There are about 65 different species of mosquitoes in New York State.
To date, the Culex pipiens (the Northern house mosquito) and Aedes japonicus
species are the only mosquitoes in New York State associated with West
Nile virus, an infection that can cause encephalitis.
Culex mosquitoes lay their eggs in stagnant water around the home. They
can develop in any stagnant water that lasts more than 4 days. Weeds,
tall grass and shrubbery provide an outdoor home for adult Culex mosquitoes,
which may also enter houses through unscreened windows or doors, or broken
screens. Aedes japonicus mosquitoes, like Culex, often breed in discarded
tires.
Culex mosquitoes are most active between dusk and dawn when the air is
calm, and that is when the females are most likely to bite. However, they
may be present at any time of the day. Aedes japonicus mosquitoes feed
during the daytime and at dusk.
You can and should reduce your risk of being bitten by mosquitoes:
- Reduce or eliminate all stagnant water in your yard;
- Make sure all windows and doors have screens; and,
- Keep all screens repaired.
How many breeding sites can you find?
- Clogged gutters accumulate water and create a place for mosquitoes
to breed.
- Mosquitoes will breed in any untreated water.
- Poorly maintained ponds & swimming pools can be mosquitoe breeding
sites.
- Uncovered refuse containers & junk piles collect water in which
mosquitoes can breed.
- Such items as tires and gardening tools, when filled with water, can
breed mosquitoes.
- Do not rake leaves and other yard waste into the gutter or storm drain
because it prevents water from flowing and creates ponds that give mosquitoes
a place to lay eggs and develop.
- Crawl spaces, attic vents and broken screens allow mosquitoes to enter
your home.
- Leaky faucets provide water in which mosquitoes can breed.
Paying attention to these details will help in the containment of the
West Nile Virus.

About
Mosquitoes and Outdoor Workers
Do I need to change my safety practices when working outdoors?
It is not necessary to limit your usual outdoor work or change standard
outdoor work safety and health practices, unless there is evidence of
mosquito-borne disease in the area where you are working. Workers can
help reduce mosquito-breeding areas by making sure that wheelbarrows,
buckets, and other containers are turned upside down when not being used
so that they do not collect standing water.
What if the West Nile virus is identified in the area where I am working
outdoors?
Even in areas where mosquitoes do carry the virus, very few mosquitoes--less
than 1 percent--are infected. The chance that any one bite will be from
an infected mosquito is very small. You can reduce your risk of disease,
by reducing mosquito bites.
Precautions that you can follow to help reduce the risk of mosquito
bites include:
Wearing shoes, socks, long pants, and a long-sleeved shirt when outdoors
for long periods of time, or when mosquitoes are most active between dusk
and dawn.
Using mosquito repellent according to label directions when it is necessary
to be outdoors for long periods of time or when mosquitoes are most active.
Most repellent products contain the active ingredients permethrin or DEET.
Permethrin-containing products can be used only on clothing, not skin,
and must be used with caution. DEET is an insect repellent that can reduce
the risk of mosquito bites, but it must be used with caution. Be aware
of the possible adverse health effects when making decisions about DEET.
Products containing DEET have been associated with some health problems
such as skin reactions and eye irritations.
The NYS Department of Health recommends the following precautions
when using products containing DEET:
- Avoid prolonged and excessive use of DEET.
- Do NOT apply insect repellents in enclosed areas.
- Do NOT apply directly on your face.
- Apply ONLY to exposed skin and NOT to skin covered by clothing.
- Wash clothing separately and wash all treated skin after returning
indoors.
- DEET can be applied to clothing, but it may damage some synthetic
fabrics and plastics.
How can I avoid heat stress on hot, humid days?
If you wear a long-sleeved shirt, long pants, shoes, and socks to reduce
the risk of mosquito bites, you might be at greater risk for heat stress
on hot, humid days. To avoid symptoms of heat stress, you should:
- Wear light-colored, breathable clothing that allows moisture to evaporate
quickly.
- Use extra caution if you are required to wear clothing on the job
that limits evaporation--you could develop heat stress much more quickly.
- Drink plenty of non-alcoholic and non-caffeinated liquids to maintain
body hydration.
Can I get West Nile Virus from handling dead animals?
There is no evidence that West Nile Virus can be spread directly from
animals to people. However, gloves should be worn whenever dead animals
must be handled.
What can I do to reduce my exposure to pesticides?
As with any pesticide, you should avoid any unnecessary exposure. Although
spraying to eliminate adult mosquitoes has not been ruled out--individual
counties will make spraying decisions according to their individual needs--such
measures will be used only as a last resort.
Some precautions that you can take to minimize pesticide exposure,
if spraying does occur, include:
- Avoid eye contact with the spray if you have to be outside. If you
do get pesticides in your eyes, rinse them immediately with water.
- Wash any clothing that may have come into contact with the spray separate
from other clothing.
- Wash exposed skin surfaces with soap and water if you come into contact
with spray or treated surfaces.
What about pesticide handlers and applicators?
Applicators of restricted-use pesticides in NYS must be certified by
the NYS Department of Environmental Conservation or must work under the
supervision of a certified applicator. The certification program includes
training on the proper handling and use of pesticides. Information on
the pesticide label must be followed regarding use of protective measures
and equipment.
Public sector workers in NYS must also receive information, training,
and education about toxic substances in the workplace in accordance with
the NYS "Right to Know" Law. Requirements for using respiratory
and personal protective equipment are also enforced by the federal Occupational
Safety and Health Administration (OSHA) for private sector workers and
by the NYS Department of Labor’s Public Employee Safety and Health
(PESH) program for public sector workers in NYS.

DEET Frequently Asked Questions
The chemical N,N-diethyl-m-toluamide
more commonly known as DEET is an insect repellent that can reduce
the risk of mosquito bites, but must be used with caution. Products containing
DEET have been occasionally associated with some health problems (skin
reactions, including rash, swelling and itching; eye irritation; and,
less frequently, slurred speech, confusion and seizures). Frequent application
or saturation may not be necessary. Use as you need for your situation.
In addition, it is recommended
that you take these precautions when using repellents that
contain DEET:
* Store out of the reach of children and read all instructions on the
label before applying.
* Do NOT allow children to apply DEET themselves.
* Do NOT apply DEET directly to children. Apply to your own hands and
then put it on the child. (According to the American Academy of Pediatrics,
repellents used on children should contain no more than 10 percent DEET.)
* When applying DEET, avoid the child's face and hands.
* Avoid prolonged and excessive use of DEET. Use sparingly to cover exposed
skin only. (There is no need to treat unexposed skin).
* Do NOT apply repellents in enclosed areas.
* Do NOT apply directly on your face.
* DEET may be applied to clothing, but may damage some synthetic fabrics
and plastics.
* Wash treated skin and clothing after returning indoors.
* If you believe you or a child is having an adverse reaction to a repellent
containing DEET, wash the treated area immediately and contact your health
care provider or local poison control center.
Remember that the use of DEET is only one way to reduce
the risk of mosquito bites. Other precautions
are to wear long pants and long-sleeved shirts when in areas of high mosquito
activity. Also, eliminate items on your property in which stagnant water
can collect and serve as a breeding ground for mosquitoes.

Frequently Asked Questions About West Nile Virus
West Nile virus is a
mosquito-borne infection that can cause encephalitis. Although chances
of a person getting encephalitis are small, there are some simple steps
you can take to reduce your risk of being bitten by mosquitoes.
What is encephalitis?
Encephalitis is a viral infection. Mild cases may include a slight fever
and/or headache. More severe infections are marked by a rapid onset of
a high fever with head and body aches. Usually symptoms occur from 5 to
15 days after exposure. There is no specific treatment for viral infections,
other than to treat the symptoms and provide supportive care. Those who
may be most susceptible to encephalitis are infants, the elderly and persons
with damaged immune systems.
Do all mosquitoes transmit disease?
No. Most mosquitoes do not transmit disease. While there are about 65
different species of mosquitoes in New York State, the Culex pipiens mosquito
(the common house mosquito) is the one most commonly associated with West
Nile virus.
Where do mosquitoes live and breed?
Mosquitoes lay their eggs in stagnant water. The eggs hatch and remain
in the water until the adults mature and fly off. Weeds, tall grass and
shrubbery provide an outdoor home for adult Culex mosquitoes. They can
also enter houses through unscreened windows or doors, or broken screens.
When are mosquitoes most active?
Culex mosquitoes are most active between dusk and dawn, when the air is
calm. However, they may be present at any time of day.
What bird(s)can carry West Nile
virus? Although most West Nile virus-positive birds have been
American crows, infections also have been confirmed in other species,
including the rock dove, sandhill crane, fish crow, blue jay, bald eagle,
laughing gull, black- crowned night heron, mallard, American robin, pigeon,
red-tailed hawk, flamingo, herring gull, cormorant, kingfisher, merlin,
cooper ’s hawk, kestrel, tragopan and broad-winged hawk. It is important
to remember that there is no evidence that birds can transmit West Nile
virus to people, but gloves should be worn when handling any dead bird
or mammal.
What about domestic birds?
Although chickens have been found to become infected with West Nile virus
(even though they do not become ill from it), there have been no documented
cases of indoor pet birds being infected. It is important to remember
that birds cannot transmit West Nile virus to people.
Can my dog or cat be infected?
Although West Nile virus was identified in horses on Long Island, there
have been no documented cases of West Nile encephalitis in dogs (although
asymptomatic infection in some dogs has been documented), and only one
case documented in a New Jersey cat. It is important to remember that
animals cannot transmit West Nile virus to people.
How can I protect my family and
myself? To reduce the mosquito population around your home
and property, reduce or eliminate all standing water:
• Dispose of tin cans, plastic containers, ceramic pots or similar water-holding
containers.
• Remove all discarded tires on your property. Used tires are very significant
mosquito breeding sites.
• Drill holes in the bottoms of recycling containers that are kept outdoors.
• Make sure roof gutters drain properly, and clean clogged gutters in
the spring and fall.
• Turn over plastic wading pools and wheelbarrows when not in use.
• Change the water in birdbaths.
• Clean vegetation and debris from edges of ponds.
• Clean and chlorinate swimming pools, outdoor saunas and hot tubs.
• Drain water from pool covers.
• Use landscaping to eliminate standing water that collects on your property.
Should we stay indoors? It
is not necessary to limit any outdoor activities, unless there is evidence
of mosquito-borne disease. However, you can and should try to reduce your
risk of being bitten by mosquitoes. In addition to reducing stagnant water
in your yard, make sure all windows and doors have screens, and that all
screens are in good repair. If West Nile virus is found in your area:
• Minimize time spent outdoors between dusk and dawn.
• Wear shoes, socks, long pants and a long-sleeved shirt when outdoors
for long periods of time, or when mosquitoes are most active.
• Consider the use of mosquito repellent, according to directions, when
it is necessary to be outdoors.
What is being done in my community
to control mosquitoes? The New York State Health Department,
along with other state agencies, local health departments, colleges and
environmental groups, has prepared a plan to address the return of West
Nile virus to the Empire State, and has devised a preventive strategy
to minimize the possibility of a recurrence. Local communities are implementing
various control measures based on geographic location and level of risk.
Individual citizens’ knowledge of the situation and participation in the
process may help reduce the need for more aggressive mosquito control,
such as the aerial spraying of insecticides. For more information regarding
activities in Oneida County, contact the Oneida County Health Department
at 315-798-6400.
What else can we do?
In addition to reducing potential breeding sites on your own property,
you can encourage your neighbors, local businesses and municipal agencies
to do so as well. You can also work with local service, labor, religious
and fraternal organizations to promote community-wide clean-up drives.

Method of Treatment:
Aerial Application from two-engine aircraft
Name of Pesticide: Anvil
(sumithrin) (EPA Reg.No. 1021-1688-8329)
NOTE: Applications may
be from September 6th to September 12th depending on weather conditions.
LOCAL CONTACT NUMBERS:
Oneida County Health Department 315-798-5064
Central New York Poison Control Center 315-476-4766
Department of Environmental Conservation 315-785-2263
The EPA does not require relocating or taking special precautions
during mosquito control spraying, however, people may prefer to avoid
or minimize exposure by:
* Staying indoors
* Keeping windows shut and air conditioners and window fans off during
spraying
* Keeping children's toys indoors
* Keeping pets indoors, as well as their food, water dishes and toys
Since the effects of aerial spraying dissipate in a few
hours, it is not necessary to wash off outdoor furniture or playground
equipment before use, although doing so will not diminish the effectiveness
of the pesticide applied.

ANVIL and Mosquito Control Information Sheet
What is Anvil? Anvil
is a pesticide product that is used to control mosquitoes in outdoor residential
and recreational areas. It contains sumithrin, piperonyl butoxide and
petroleum distillate. Sumithrin is a synthetic pesticide similar to a
natural pesticide (pyrethrum) produced by chrysanthemum flowers. Piperonyl
butoxide does not directly kill insects on its own but acts to increase
the ability of sumithrin to kill insects. Other pesticide products containing
these ingredients are used indoors and on pets to control insects such
as fleas, ticks and ants.
Is the spraying of Anvil harmful
to my health or my family’s health? Because pesticides are
inherently toxic, no pesticide is absolutely risk free. The likelihood
of experiencing adverse health effects as result of exposure to any pesticide,
including Anvil, depends primarily on the amount of pesticide which a
person contacts and the amount of time the person is in contact with that
pesticide. In addition, a person’s age, sex, genetic makeup, life style
and/or general health characteristics can affect their likelihood of experiencing
adverse health effects as result of exposure to pesticides. Accidental,
short–term exposures to very high levels of pyrethroid pesticides similar
to sumithrin can affect the nervous system, causing effects such as incoordination,
tremors, or tingling and numbness in areas of skin contact. Short-term
exposures to high levels of petroleum distillates can cause irritation
of the eye, skin, nose, throat or lung. Vomiting or central nervous system
depression may occur if very high levels of petroleum distillates are
ingested.
There are no studies examining whether or not the use of
Anvil to control mosquitoes has caused any long-term health effects in
humans. Since Anvil is applied at very low concentrations, it is unlikely
that adverse health effects will occur as a result of its use to control
mosquitoes. Nevertheless, some individuals may experience health effects
as a result of short-term exposure to the very low levels of Anvil used
to control mosquitoes. For these reasons, individuals should consider
taking common sense steps to minimize their exposure to Anvil if it is
applied to control mosquitoes.
Is Anvil an "endocrine disruptor"?
"Endocrine disruptors" are chemicals which interfere with endocrine system
function. The endocrine system consists of glands which produce hormones
that act together to guide development, growth, reproduction and behavior,
and to maintain normal organ function. High concentrations of sumithrin
acted like estrogen (a naturally occurring hormone) when it was added
to cells growing in plastic dishes in a laboratory. This suggests that
sumithrin may interfere with endocrine system function in whole animals.
Although changes in thyroid hormone levels occurred in animals
repeatedly exposed to some other pyrethroids, there are no specific studies
examining whether or not sumithrin or the other components of Anvil, piperonyl
butoxide or petroleum distillate, interfere with endocrine system function
in whole animals. Our knowledge of the relationship between exposure and
endocrine system effects is still developing. Because of the low application
rates and rapid environmental breakdown of pyrethroids, it is unlikely
that endocrine system effects would be experienced if they are used to
control mosquitoes.
Are some people more likely than
others to experience symptoms after they have been in contact with Anvil?
Most people would not be expected to experience any symptoms. However,
there could be some individuals who may be particularly sensitive to one
or more constituents of Anvil, and could possibly experience short-term
effects such as eye, skin, nose or throat irritation or breathing problems.
Children, in particular, may be at greater risk of experiencing adverse
effects due to the application of Anvil since they may have the potential
for greater exposures than adults.
If I’m pregnant, can the spraying
affect this pregnancy or harm my baby? Neither sumithrin nor
piperonyl butoxide is likely to affect pregnancy outcomes in people as
a result of spraying. Although some effects occurred in laboratory animals
that were given large amounts of either sumithrin or piperonyl butoxide,
these amounts far exceeded the amounts that individuals are likely to
contact from the spraying with Anvil.
Should I be concerned about cancer
because of the spraying program? Available information suggests
that Anvil is not likely to cause cancer if people are exposed during
or following the spraying program. Sumithrin did not cause cancer in rats
or mice when they were fed high levels for their lifetime. Experimental
studies have reported that piperonyl butoxide causes liver tumors in rats
and mice when they are fed high levels of piperonyl butoxide every day
for a long period of time. The amount of piperonyl butoxide ingested by
animals in these studies, however, far exceeds the amount humans might
be exposed to as a result of the use of Anvil to control mosquitoes. All
available information thus indicates that piperonyl butoxide is unlikely
to cause cancer in humans as a result of its use to control mosquitoes.
Can pets go outside during the
spraying? If you want to reduce your pets’ exposure, keep them
inside during the spraying. As mentioned above, products containing sumithrin
and piperonyl butoxide can be applied directly on pets to control ticks
and fleas.
Should I be concerned about my
private swimming pool? Anvil breaks down fairly quickly in
water and in sunlight. If possible, you may want to cover your pool before
the spraying occurs. However, given the small concentrations of Anvil
being sprayed, no special precautions or waiting periods are recommended
for swimming pools.
What can I do to reduce my exposure
to the insecticide? The chance of experiencing any health effects
from the use of Anvil to control mosquitoes is quite low. As with any
pesticide, you may want to reduce or eliminate exposures that are not
necessary.
The following common sense steps will help reduce possible
exposures to Anvil during spraying:
* If possible, remain inside whenever spraying takes place.
* Keep children inside during spraying and for about 1 hour after spraying.
* Close windows and doors and turn off your air conditioning (or set
it to circulate indoor air) before spraying begins.
* If you have to remain outside, avoid eye contact with the spray.
* If you get Anvil spray in your eyes, immediately rinse them with water
or eye drops.
* Wash exposed skin surfaces with soap and water if you come in contact
with Anvil spray.
* Rinse homegrown fruits and vegetables thoroughly with water before
cooking or eating.
* Cover outdoor tables and play equipment or rinse them off with soap
and water after they have been sprayed.
* Bring laundry and toys inside before spraying begins (wash with soap
and water if exposed to Anvil during spraying).
* Bring pets and pet food and water dishes inside, and cover ornamental
fishponds to avoid direct exposure.
* Consult your physician if you think you are experiencing health effects
from spraying.
