It is estimated that there are about 10,000,000,000,000,000,000 insects living today. That’s right, a quintillion
insects.
In the world, there are about 900 thousand different kinds of living insects, making
up about 80% of all of the world’s species. In the U.S. alone there are 91,000 known species
and about 73,000 that have yet to be scientifically described and classified.
While the insects on this list are nowhere near being the deadliest animals on earth,
these bugs really do make their mark… sometimes literally, sometimes remarkably- particularly
for living things that are no bigger than a human finger.
Below is a list of ten insects that you definitely don’t want to run into:
10. House Centipedes (Scutigera coleoptrata)
Originating in the Mediterranean (or Mexico, depending on the source), the house centipede
has become a very common bug around the world. You may think centipedes look unattractive
but they are actually “good” bugs, as they eat other pests and sometimes even spiders.
Of course, if you have entomophobia (fear of insects or bugs), then this argument isn’t
going to help. In any case, centipedes are more of a pest than they are a threat, but
shockingly they can cause some damage. If you are bitten by one of these insects, you’ll
definitely feel it. Some who have experienced it say that it is painful, but nothing that
will send you off crying in the corner.
What’s to Fear?
While centipedes aren’t insects that are responsible for tons and tons of deaths, you’d
be surprised to find out that every two years one person does die due to a centipede bite.
This is usually due to an allergic reaction to the venom that the bug can inject into
your body when it bites you. However, it’s rare that one is so allergic to this venom
that it kills them.
9. Fire Ants (Solenopsis) Deadly Bugs: Fire ants sting their prey and
the inject venom
While having a picnic with ants doesn’t sound so bad, as most ants are harmless and
miniscule compared to the human body, having a picnic with fire ants definitely isn’t
the wisest idea. There are over 280 different species of ants that sting and one of the
most widely known is the fire ant. Other ants kill by stinging their prey and then spraying
the wound with acid, but the fire ant is particularly ruthless. They kill by stinging their prey
and then injecting venom known as solenopsin. And because of this, when a human is stung
by the ant, it can be compared to the sensation felt when being burned; however, the sting
is usually minor and something that the body can fight on its own.
What’s to Fear?
As you’d imagine, a little ant can’t do much damage to a human. All we’d have to
do is make a little use of our left shoe. However, ants live in colonies and sometimes,
with enough stings and enough bodily sensitivity, the fire ants can kill. It is said that about
5% of those who report being bitten by a fire ant die due to anaphylactic shock. Of course
this is very far and in between, but there are reports of deaths caused by an allergic
reaction to the venom.
8. Siafu (Dorylus)
Very similar to fire ants, Siafu are ants that are mainly located in east and central
Africa, but they can also be found in parts of Asia. These ants are said to live in colonies
of 20 million ants, notably 20 million blind ants. They are able to travel through the
use of pheromones. Out of these 20 million, there is a group of ants known as the soldier
ants. These ants are the ones that are able to sting to fend off or kill prey. It is said
that while the ants are able to sting, they often use their jaws, made for shearing, to
bite. The jaws of these ants are so strong that in some locations in Africa, they are
actually used as sutures which can hold for up to four days, to allow wounds to heel properly.
What’s to Fear?
If one is stung by a Siafu, the bite is often very minimal and nothing that requires a doctor.
However, it is said that the young and elderly are very susceptible to their bites, and some
have died due to complications caused by the ant bite. Around 20-50 people reportedly die
each year from a Siafu bite. These ants are often very aggressive and when you interrupt
their colony, you just may be in a little bit of trouble.
7. Wasps and Bees (Vespula germanica/Apis mellifera)
As pesky as they are, wherever you go, you’re sure to find wasps and bees. On flowers, near
something that smells sweet, or making a hive in a very inconvenient place- wasps and bees
are an everyday part of life when the weather is warm enough to permit it. You’ve probably
been stung at least once so you know what it feels like. It’s usually not an event
that requires medical attention – unless you’re allergic.
What’s to Fear?
If you’re not allergic to a wasp or bee sting, then you really have nothing to worry
about. If you are allergic to wasp or bee stings, then getting stung might be more of
a problem. It is said that about 53 people die each year because of an allergic reaction
from being stung. Those who are allergic to the venom let off after being stung can go
into anaphylactic shock, which often brings about hives, wheezing, confusion, pale skin,
and sometimes unconsciousness and even death.
6. Asian Giant Hornet (Vespa mandarinia)
You’ve probably seen a hornet once in your life and you probably weren’t too fearful
of it as they are usually pretty small and pretty easy to rid of. However, imagine a
hornet on steroids, and when you do, just look to the Asian Giant Hornet. This hornet
is said to be the biggest in the world, with a length of 2 inches and a wing span of 3
inches. The hornet also sports a ¼ inch long stinger, but being stung with by this hornet
is definitely not like being stung like a bee. While you won’t find these hornets
anywhere near the U.S. or Europe, if you ever make a trip to Eastern Asia, you’re sure
to run into them a few times, especially if you travel the mountainous places in Japan.
What’s to Fear?
Take it from someone who has experienced it. According to Masato Ono, someone who has been
stung by an Asian Giant Hornet, the sting felt like a “like a hot nail being driven
into his leg.” The venom that is released by the stinger has about 8 different compounds,
one that causes discomfort, one that can damage soft tissue, and one that is able to create
an odor that may attract even more hornets. Those who are allergic to bees can die from
the reaction, but some die because of a chemical known as mandaratoxin which can be fatal if
there is enough introduced into the body. It is said that each year, about 70 people
die from these stings.
5. Africanized Honey Bee (hybrid Apis mellifera scutellata)
While most of us can deal with normal bees, the ones that we see all the time in our gardens,
if you ever come into contact with an Africanized Honey Bee, you’re definitely in for some
trouble. Though normal bees do sting, being stung by a honey bee is much different, as
it’s unlikely that you’ll just be stung once since they hang around in swarms. In
1956 these bees were brought to Brazil in order to breed a more efficient honeybee.
However, this failed and most of the bees were able to escape. From Brazil the swarms
of bees have reached Central America and have even come as far up as the southwestern U.S.
What’s to Fear?
Because they are known to travel in swarms, when a bee attacks a victim, many of the other
bees will do so as well. It is said that one swarm of these bees can take down a horse.
The bees have killed about 1,000 people since they’ve started coming up from Brazil. These
bees definitely put a face to the name killer bees.
4. Kissing bug (Triatomines)
First discovered in the 19th century by Charles Darwin, the kissing bug is an insect that
you don’t ever want to come into close contact with. There are 138 known species in existence.
Most of them are within the U.S., with others scattered throughout Asia, Australia, and
Africa. All of the known species are said to be able to transmit Trypanosoma cruzi,
a very harmful parasite that can be fatal. Most species of the insect are known to live
off of vertebrate blood while some are able to live off of invertebrates.
What’s to Fear?
The potentially lethal kissing bug is known to live in the same dwellings as humans, often
making their homes on the outside as well as the inside of our houses. It is said that
45,000-50,000 people die each year from kissing bug bites. This is because the parasite that
the bug carries, Trypanosoma cruzi, is known to cause Chagas disease, which seems very
minute at first but is fatal over. At first there is just swelling at the site of the
bite, but then the disease can lead to intestinal issues as well as cardiac problems. In fact
most of those who die from Chagas disease die from Chagasic cardiomyopathy.
3. Tsetse Fly (Glossina morsitans)
While flies alone are annoying, imagine a fly that lives by sucking blood from animals
and humans. The tsetse fly is found in the Kalahari and Saharan deserts. This insect
is widely studied today due to the disease that they transmit. The flies look very similar
to the normal housefly we all love to swat at, except for a proboscis on their head,
which is the anatomical part that allows them to suck blood. There are 34 different species
of tsetse flies, all of them fitting into one of the three categories: savannah fly,
forest fly, or riverine fly.
What’s to Fear?
Though a little fly may seem pretty harmless, the tsetse fly can kill, and do so each year.
Most of the deaths are in Africa- it is said that 250,000 to 300,000 die each year from
something known as the sleeping disease (the numbers are slowly decreasing). The tsetse
fly carries protozoa known as trypanosomes, but so do many other insects. However, when
someone is bitten by the tsetse fly, the protozoa are introduced to the body and cause a disease
known as the Sleeping Sickness. If not treated properly, the disease is able to shut down
necessary bodily functions, such as the endocrine and cardiac systems. Next, the disease enters
the neurological system, causing confusion and an abnormal sleep cycle due to insomnia
and slumber. The most recent notable epidemic of the disease was in Uganda in 2008.
2. Rat Fleas (Xenopsylla cheopis)
When thinking of fleas, you probably think of a tiny insect that has landed on a household
cat or dog that causes a lot of itching. Fleas are often only 1/16 to 1/8 inch long, with
a dark colored body and a mouth that is made to be able to suck blood off of the helpless
host it lands on. A flea bite, whether on your pet or your own body, will often cause
a red mark accompanied by a lot of itching. Though there are different types of fleas
that you’d find on a dog or cat, one of the more deadly fleas is one you’d find
on a rat. While rats are pretty scary to most on their own, a flea-infested rat is even
scarier, and is one that needs to be avoided.
What’s to Fear?
While fleas are often no bigger than the nail on your pinky finger, they have been known
to carry devastating diseases and germs, the most notable being the Yersinia pestis bacteria.
This bacteria is known for causing the death of nearly three-quarters of Europe’s population
during the 14th century. Better known as the Black Death, this plague killed between 350
and 375 million people and peaked during 1348-1350. The rats that were often found on merchant
ships are said to have spread the disease and, due to lack of medical information and
treatment, the disease spread and spread. The plague was also never fully wiped out
and for years there would be a reoccurrence of deaths due to the deadly bacteria. While
today dying from this bacteria would be rare in the U.S. and in most places in Europe,
in many third-world countries it is very possible.
1. Anopheles Mosquito (Anopheles quadrimaculatus)
Once the temperature outside hits a steady stream of temperatures above 50°F (10°C),
you’ll surely start to see those pesky mosquitoes flying around outside. You are even more likely
to see them once the sun begins to go down. As if dealing with bugs isn’t a nuisance
in itself, mosquitoes are a bit more to deal with, especially if one lands on you and decides
to bite. While only female mosquitoes will bite a human, some of them carry diseases
that can be very harmful. There are about 3,500 species of mosquitoes, 200 of those
living in North America, many carrying ailments such as yellow fever, dengue, encephalitis,
and even canine heartworm.
What’s to Fear?
A mosquito has probably bitten you at least once before in your life, so you’re familiar
with the little red bump that may swell and really itches- nothing a little cortisone
or anti-inflammatory skin cream won’t fix. However, in some cases, a mosquito bite can
lead to a lifetime of illness, or even lead to death. One of the most widely known mosquito-borne
diseases today is malaria. It is very prevalent in tropical countries: there are about 350–500
million cases found each year and about 1-3 million people die from it each year. Malaria
is said to affect at least 10% of the world’s total population. These deaths are usually
noted in sub-Saharan Africa where mosquitoes are very prominent and proper care for malaria
is scarce.
