I have been getting lots of mosquito bites that I feel if every bite has monetary value I should be a millionaire by now. I practically killed over 30 mosquitoes last night, I barely slept.
That prompted me to do a bit of research about them just to understand how they operate and their make up maybe I can finally find the most effective way of eliminating them from my home.
Permit me to share with you amazing facts about mosquitoes...
-
Female mosquitoes need protein in blood to help
her eggs develop. Once she's had her fill of blood, she'll rest for a couple of
days before laying her eggs.
-
There are more than 3,500 species of mosquitoes.
About 175 of them are found in the United States, with the Anopheles
quadrimaculatus, Culex pipiens,Aedes aegypti and Aedes albopictus (Asian tiger
mosquito) among the most common.
-
The Anopheles is a malaria carrier, and the
other three are known to spread various forms of encephalitis.
-
West Virginia has the fewest species of
mosquitoes. There are 26 in the mountainous state, while Texas has the most
with 85. Florida is a close second with 80 identified species.
-
Mosquito is Spanish for “little fly.” The word
reportedly originated in the early 16th century. In Africa, New Zealand and
Australia, mosquitoes are often called “Mozzies”
-
Mosquitoes don't have teeth. The females “bite”
with a long, pointed mouthpart called a proboscis. They use the serrated
proboscis to pierce the skin and locate a capillary, then draw blood through
one of two tubes.
-
A mosquito can drink up to three times its
weight in blood. Don't worry, though.
-
Female mosquitoes can lay up to 300 eggs at a
time. Usually, the eggs are deposited in clusters – called rafts – on the
surface of stagnant water, or they are laid in areas that flood regularly. Eggs
can hatch in as little as an inch of standing water. Females will lay eggs up
to three times before they die.
-
Mosquitoes spend their first 10 days in water.
Water is necessary for the eggs to hatch into larvae, called wigglers. Wigglers
feed on organic matter in stagnant water and breathe oxygen from the surface.
They develop into pupae, which do not feed and are partially encased in
cocoons. Over several days, the pupae change into adult mosquitoes.
-
Mosquitoes hibernate. They are cold-blooded and
prefer temperatures over 80 degrees. At temperatures less than 50 degrees, they
shut down for the winter.
-
The adult females of some species find holes
where they wait for warmer weather, while others lay their eggs in freezing
water and die. The eggs keep until the temperatures rise, and they can hatch.
-
Mosquitoes have six legs. They also have a head,
thorax and abdomen. On the head are two large compound eyes, two ocelli (simple
eyes), two antennae and a proboscis. Two large, scaled wings sprout from the
thorax.
-
Midges and crane flies are often mistaken for
mosquitoes. Biting midges are smaller, have shorter wings and tend to feed in
swarms. Mosquito traps often attract and kill biting midges. Meanwhile, crane
flies are much larger than mosquitoes – up to 1 ½ inches long in some cases –
and do not bite.
-
Male mosquitoes locate females by the sound of
their wings. Females can beat their wings up to 500 times per second, and the
males pick out the higher frequency of those beats when seeking a mate.
-
Mosquitoes can't fly very far or very fast. Most
mosquitoes can fly no more than about one to three miles, and often stay within
several hundred feet of where they were hatched. However, a few salt marsh
species can travel up to 40 miles. The top speed for a mosquito is about 1.5
miles per hour.
-
Mosquitoes generally fly below 25 feet. However,
some species have also been found at extraordinary heights, including 8,000
feet up in the Himalayas.
-
Mosquitoes can smell human breath. They have
receptors on their antennae that detect the carbon dioxide released when we
exhale. Those plumes of CO2 rise into the air, acting as trails that the
mosquitoes follow to find the source.
-
Sweat helps mosquitoes choose their victims. Our
skin produces more than 340 chemical odors, and some of them smell like dinner
to mosquitoes. They are fond of octenol, a chemical released in sweat, as well
as cholesterol, folic acid, certain bacteria, skin lotions, and perfume.
-
Body heat marks the target. Mosquitoes use heat
sensors around their mouthparts to detect the warmth of your body – actually,
the blood inside it – then land on you and locate the best capillaries for
tapping.
-
Mosquitoes feed day and night. Some species,
like the Aedes are daytime biters, while others, like Culex, start biting at
dusk and continue a few hours into dark.
-
Mosquitoes have been around since the Jurassic
period. That makes them about 210 million years old. They've been mentioned
throughout history, including in the works of Aristotle around 300 B.C. and in
writings by Sidonius Apollinaris in 467 B.C.
-
Mosquito has 48 teeth in his mouth.
-
The bumps from mosquito bites are caused by
saliva. While one tube in the proboscis draws blood, a second pumps in saliva
containing a mild painkiller and an anti-coagulant. Most people have minor
allergic reactions to the saliva, causing the area around the bite to swell and
itch.
-
Malaria is caused by a parasite that lives in
mosquitoes. The parasite gets into mosquito saliva and is passed on when the
insect bites someone. West Nile and other viruses are passed the same way.
Mosquitoes can also carry and pass on canine heartworm.
-
West Nile virus came to the U.S. in 1999.
Scientists first identified it in a feverish woman in Uganda – the West Nile
district – in 1937. There were large outbreaks of the virus reported in Israel,
South Africa, and Romania up through the late '90s. The virus first appeared in
the United States in 1999 with an epidemic in New York.
-
Mosquitoes do not transmit HIV. The virus that
causes AIDS does not replicate in mosquitoes and is actually digested in their
stomachs, so it's broken down without being passed on.
-
Mosquitoes are considered the deadliest “animal”
in the world. The Anopheles mosquito, in particular, is dangerous because it
transmits malaria, which kills more than one million people every year,
primarily in Africa. Alexander the Great is believed to have died of malaria in
323 B.C.
-
DEET is considered the 'gold standard' of
mosquito repellents. Endorsed by the Centers for Disease Control (CDC), DEET
doesn't mask the smell of the host or jam the insect's senses - mosquitoes
simply don't like it because it smells bad to them. A product containing 10
percent DEET can protect you for up to 90 minutes. Two other repellents,
picaridin and lemon-eucalyptus oil, have also proven effective and are now
recommended by the CDC.
-
Bacteria can be used to kill mosquito larvae.
Bacillus thuringiensis israelensis (Bti) is a commercially-produced bacteria,
sold in pellet and powder form, that can be laced into water where larvae live.
It produces proteins that turn into toxins after the larvae eat it.
-
Insecticides work, but only in the short term.
Permethrin, one of the most common chemicals used by local mosquito control
programs, kills mosquitoes on contact by disrupting their central nervous
systems. However, eggs and larvae often are not affected. Once the insecticide
dissipates, mosquitoes can return.
-
Bats do not eat mosquitoes. At least, not very
many of them. Mosquitoes make up less than 1 percent of a bat's diet. And
purple martins, a bird popularly believed to be a mosquito predator, eat very
few mosquitoes. They prefer dragonflies and other insects.
-
The two main mosquito predators are fish and
dragonflies. Gambusia, or mosquitofish, feed on mosquito larvae and are used
all over the world to help control mosquito populations. Dragonfly larvae,
called nymphs, eat mosquito larvae, and adult dragonflies prey on adult mosquitoes.
Some towns in Maine release dragonflies every summer as a natural form of
mosquito control.
-
Mosquito traps can kill thousands of mosquitoes
in a single night. One study conducted by public health researchers in
Australia found that a Mega-Catch™ trap caught and killed more than 44,000
female mosquitoes from 17 species in less than two weeks.
-
Bug zappers are useless against mosquitoes.
Studies have shown that less than 1 percent of the insects killed by zappers
are mosquitoes or other biting insects. The devices attract and kill beneficial
or harmless insects, like moths, and have no effect on the overall mosquito
population. Electronic repellers have also proven ineffective in scientific
testing.
-
Insecticide-treated nets (ITNs) that hang over a bed have been
shown to reduce malaria incidenceamong children and
pregnant women by up to 50 percent. The nets last only a few years before they
have to be replaced.
-
How long does a mosquito live after biting
someone? Only female mosquitoes bite and feed on the blood of humans or
warm-blooded animals. If a mosquito finds enough victims to bite and avoids
being squashed, it can live as long as three weeks. During that time, it may
lay up to five clutches of more than 100 eggs each.
-
Mosquitoes are responsible for spreading several
harmful diseases such as Malaria, Zika and Dengue to name a few. It is believed
that as a result of this, mosquitoes are responsible for around 1 million
deaths per year!
-
It has been discovered that before mating
mosquitoes engaged in a sort of dance which involves beating their wings in a
call-and-response type of manner.
-
Do mosquitoes sleep at night? Yes they do.
Unfortunately, they don't like to sleep at the same time we do. Most mosquitoes
are active at night or at dusk and dawn, and rest or sleep during the day. They
look for sheltered places, such as brush or thick weeds, caves or rock
shelters, holes in the ground, hollow logs or holes in trees.
-
How many times can a mosquito bite? A female
will continue to bite and draw blood until her abdomen is full. If she is
interrupted before she is full, she will fly to the next person. After feeding,
the mosquito rests for two or three days before laying her eggs, then is ready
to bite again.
-
Do mosquitoes only bite humans? Only female
mosquitoes bite humans and animals; males feed on flower nectar. And when not
trying to produce eggs, females are happy to stick to nectar, too.
-
What do mosquitoes not like the smell of? If you
prefer to take a natural approach, there are numerous plant-based oils that can
be effective at keeping mosquitos away — peppermint, cinnamon, citronella,
cedar, clove, lemongrass, rosemary, thyme, lavender, catnip, patchouli, tea
tree oil, eucalyptus and sage, to name a few.
-
Can a mosquito bite kill you? For an average
person, losing two liters of blood becomes life-threatening. The average
mosquito bite drains 0.01 to 0.001 milliliters of blood. Thus it would take
somewhere between 200,000 and 2 million mosquito bites to kill you from blood
loss.
- Which seems unlikely, but then again in the Arctic, Canadian researchers who bared their arms, legs, and torsos reported as many as 9,000 bites per minute from swarming, newly hatched mosquitoes. At that rate, an individual could lose half his blood in two hours.
-
Once a feeding mosquito is full, a chemical signal shuts down the
intake. When that signal is disabled in the lab, mosquitoes suck until they
explode.
-
Do male mosquito bite? The female mosquito is
the one that bites (males feed on flower nectar). She requires blood to produce
eggs. Her mouthparts are constructed so that they pierce the skin, literally
sucking the blood out. Her saliva lubricates the opening.
-
Millions of years ago,
mosquitoes were three times as large as they are today.
-
How long do mosquitoes live without food? The
average mosquito lifespan is less than two months. Males have the shortest
lives, usually 10 days or less, and females can live about six to eight weeks,
under ideal conditions. The females lay eggs about every three days during that
time. Females of species that hibernate may live up to six months.
-
Why Do Mosquitoes Buzz in People's Ears?
Mosquitoes' wings make that annoying buzz or whining sound whenever they fly.
When they circle your head, looking for a place to land and bite, their buzz
sounds louder whenever they're close to your ear. ... So they stay away from
your ears, eating nectar, while the females come near to annoy you.
-
Do mosquitoes die after they mate? Mating in
mosquitoes is quick, sometimes lasting no more than 15 seconds, and usually
takes place in the air, though it can also occur on a surface. ... Unlike male
mosquitoes, which will continue to mate until they die, most female mosquitoes
will mate just once.
-
Can mosquitoes see you? Many insects, mosquitoes
included, are attracted by the odor of the carbon dioxide (CO2) gas that humans
and other animals naturally exhale. However, mosquitoes can also pick up other
cues that signal a human is nearby. They use their vision to spot a host and
thermal sensory information to detect body heat.
-
What color are mosquitoes attracted to most?
Mosquitoes are attracted to dark colours, not only black, because dark colours
absorb heat and lighter colours tend to reflect heat. Since mosquitoes have
sophisticated and highly sensitive heat sensors, they tend to be more attracted
to victims dressed in darker clothes, where there is more heat.
-
Abuja, Nigeria, is home to the world’s biggest mosquito net, unveiled in 2000as part of a national campaign against malaria
and other insect-borne diseases. Two hundred children fit under it.
-
X-ray machine in insects: In the body
of this insect is a digital X-RAY machine. It uses it to distinguish the human
skin in the dark in violet color.
-
Mosquitoes are more attracted to women than to men.
- Millions of people alive today will die of a mosquito-transmitted disease. Malaria alone claims some 1,000,000 lives a year in Africa. Other top killers include dengue, yellow fever, and West Nile virus.
