Along with heights, a fear of spiders
has to be one of the most common phobias humans have. Most experts
believe it is because in our evolutionary past we dealt with poisonous
spiders and therefore we developed a phobia of them as a survival
mechanism. These days, spiders are all over the world and they come in
many shapes and sizes, along with degrees of poison. So if you hate
spiders, you should probably stop reading now but if you hate spiders,
you should also keep reading to know the countries to avoid.
1.
Laos: Home of the Largest Spider
The Giant Huntsman Spider is justly
named since it is the largest spider in the world in terms of leg span.
Its leg span is a very large spider with a leg span of one foot. One
foot may not seem like much compared with birds, rodents and more, but
for a spider it is downright terrifying. First discovered in 2001 in
Laos, over the past ten years, over 1,000 new species have been found in
the entire Greater Mekong Sub-region. Many were very surprised that a
spider this large went undiscovered for so long. As the World Wide Fund
for Nature said, “Some of these species really have no business being
recently discovered.”
Experts believe that it is a cave-dwelling spider because of its pale color, so make sure you stay out of the caves in Laos!

Brazil: Home of the Second Largest Spider
Okay, the Giant Huntsman Spider is big,
and while it is the largest spider, it may not be the scariest one that
you come across. That title goes to Goliath Birdeater, which is found in
South America and primarily in Brazil. It is a member of the tarantula
group and was believed to be the largest spider in the world until the
Giant Huntsman was discovered. The reason that it was named the Goliath
Birdeater Spider is because explorers in the 19th century witnessed it
eat a hummingbird.
With a leg span of 11 inches and a
weight of six ounces, it is a deep-burrowing species found in swampy
areas. Sadly for the males, females will mate with them and then kill
the mates and the females will typically live for as long as 25 years.
This spider may be large, but it is pretty harmless to humans beyond
giving them a heart attack. Most describe the venom from the spider to
feel like a wasp sting. The species typically eats insects, but it has
been found to eat rodents, lizards, bats and even some snakes.

Brazil: Home of the Most Venomous Spider
Okay, another big reason to avoid Brazil
if you hate spiders. Not only do they have a very large spider, they
have a very poisonous spider. In fact, they have the most venomous
spider in the world; The Brazilian Wandering Spider.
The Brazilian Wandering Spider is a highly aggressive and venomous
spider found all over South and Central America, and especially in
Brazil.
It is called the Brazilian Wandering
Spider because it wanders the jungle floor at night, instead of staying
in a web. During the day, the spider can be found in termite mounds,
fallen logs and in banana plants. It will also hide in dark and moist
places in or near where humans live.
If you are bit by this spider, the
neurotoxin will cause you to lose muscle control, your breathing will
become labored and eventually you will become paralyzed and asphyxiation
will begin. Not only that, you can expect intense pain and inflammation
due to the venom. One odd thing that the bite also causes is an
erection that will last for many hours, will be very uncomfortable and
may leave you impotent.
Since the spider wanders, it is very
dangerous to humans, especially in areas that are densely population. It
will hide in clothes, cars, boots and in boxes which leads to sudden
bites on hands and feet when it is surprised. It can also travel around
the world in banana crates, where it ends up in grocery stores. This
happened in Bridgewater, England when a man was bitten by one of the
spiders. He survived but it took him an entire week to recover.
4.
Australia: Home To Spider Attacks
While Australia only ranks ninth in
terms of contact with venomous spiders, per capita, at .14 deaths per
1,000,000 people, it is still a place with plenty of deadly spiders. In
fact, many feel that Australia may have the most deadly spiders on
Earth.
Just some of the spiders found in Australia that can harm humans include:
• The Australian Funnel-Web Spider is
one of the most dangerous in the world and will often bite rather than
run away. It is typically found within 100 km of Sydney and its toxin is
highly toxic to primates. Males have more potent venom than females and
are often encountered in the summer time. Bites from the males have
resulted in death if medical attention is not sought.
• The Redback Spider does not bite often
but when it does it is highly toxic and dangerous for the elderly and
children. Roughly 20 percent of those bitten by the spider require
treatment. There have been no deaths since 1956 when the antivenom was
created and most of the bites are from female spiders. Typical symptoms
usually involve mild pain that is short-term. Of course, bites can also
cause extreme pain and sweating, as well as swelling and swollen lymph
nodes. Other issues that can result from the bite include seizure, coma,
respiratory failure and more depending on the person who was bitten.
• The Mouse Spider is a burrowing spider
that has a deadly venom, which can cause serious harm to humans. Severe
symptoms can develop, which require emergency medical treatment but
bites are rare and there have been no recorded human deaths.
• The Australian Huntsman Spiders are
not very aggressive but they will defend their nests and make threat
displays to humans who tread too closely. They can move rapidly and they
will often enter houses. IF you are bit, they symptoms are very
unpleasant but not life-threatening.
• The White-Tailed Spider is not as
dangerous as other spiders, but it is still not pleasant to be bit by
one. Its bite usually causes the same type of symptoms as a bee sting,
but on occasion nausea, vomiting and headache can develop.
Spiders are not very pleasant for most
of us and while only a few are truly dangerous to humans, we all fear
them. Whether it is a Daddy Long-Legs or a Huntsman Spider, we all feel
fear when we come across a spider. If you live somewhere like Canada,
then you don’t have too many big spiders, but if you live in Brazil,
Laos, or Australia, you may deal with spiders that truly do make your
skin crawl.
