Mosquitoes
Of all the creatures on earth, mosquitoes may
well pose the greatest threat to man's health
and existence. Diseases transmitted by mosquitoes,
such as Malaria, West Nile virus, Yellow Fever,
Filariasis, Dengue Fever and Encephalitis kill
and debilitate millions of persons world wide
even with today's advances in medicine. As a
nuisance biter, they can also have a major negative
impact on a local economy by inhibiting recreational
or work environments.
Early life stages of mosquitoes (larvae and
pupae) must have water in which to survive. Any
object capable of retaining water for five or
more days is a potential breeding site.
The length of an adult mosquito's life under
natural conditions is only a few weeks during
the summer months. Mating usually takes place
within a 24 to 48 hours after adults emerge.
Mosquitoes have a tremendous potential for reproduction.
A female mosquito, depending on species can produce
about 50 to 500 eggs in her first brood. If we
consider and average of just 200 eggs per brood
(half of which would be female) and that a mosquito
can complete its development in less that two
weeks, we can obtain, in only five generations,
around 20 Million mosquitoes. If we can get 20
million offspring from only one female, thousands
of females may produce billions or trillions
of mosquitoes.
Females, depending on species, will feed at
any time of the day or night. Some feed on people
only when they wander into the areas in which
they live. Others will fly 5 to 10 miles to feed.
Still others seek us out inside our own homes.
How do I protect myself against Mosquitoes?
Mosquito control is problem that is best handled
by the community and public health agencies rather
than by the individual homeowner. Because breeding
places for mosquitoes are often situated at considerable
distance from the place of annoyance, we look
to these public agencies to address these situations
for us. Unfortunately, many of these programs
are extremely limited or, in many communities
do not exist at all. On a very local basis, such
as your home, business or yard, proper application
of materials to surrounding vegetation where
the adult mosquitoes rest can offer control for
several hours or longer. The myth perpetuated
to the public, is that electric bug zappers,
ultrasonic repelling devices and citronella candles
can offer effective mosquito control. Such methods
have little or no effect to relieving the stress
of mosquito attacks around structures. Others,
claim to attract mosquitoes by mimicking body
heat or by generating carbon dioxide (which is
a strong attractant for mosquitoes). These devices
often make the situation worse by attracting
many more mosquitoes than they kill, in effect
drawing the mosquitoes to your property!
