There are six known spiders that are deadly to man. They include:
|
Varied widow |
|
Red-legged widow |
|
Brown widow |
|
Black widow |
|
Sak spider |
|
Brown Recluse |
I will talk about two of them here.
THE BLACK WIDOW
Contrary to popular belief, only five percent of those
bitten by a female black widow spider actually die.35
It is only the female that should be feared because the male is
virtually harmless. If the black widow bites, it was probably
because she was squeezed against someone's skin. She prefers to mind
her own business.
THE BITE
|
If someone is bit, they will feel a bit of a pin prick
sensation. This will be followed by a dull numbing pain throughout
the extremity. The venom may cause the feeling of a heart attack or
appendicitis. During this, nausea, headache, vomiting and black
widow face may occur. Black widow face is having red, swollen, droopy
eyelids. The complexion will become flushed and jaw muscle spasms
also occur. Mental psychosis occurs in severe cases. Heart
failure can occur in very young victims, very old victims or victims that
have been bitten several times. There are no known medical remedies
for this, but there is an anti-venom that works on red- and brown-widows
available.36

THE NAMESAKE
|
The spider got the name because of the female's mating
ritual. She kills her mate after he impregnates her and devours him
as a post intercourse snack. One source mentioned that if he does
get away, he will die in a few days anyway because his male sex organ
breaks off during violent intercourse. This is a misnomer.
Actually, when black widows mate, the male cautiously advances toward her.
If the female is receptive, she will allow him to slowly advance closer.
Eventually, he reaches her and is able to touch her with his legs.
With her consent, be bonds her with his silk. It is not strong
enough to hold her for good. After she is bonded, he impregnates her
and leaves as soon as possible. She comes out of her "spell" and
breaks her bonds with ease. The bonds give the male an extra split
second to get away. If she has the urge, or is hungry enough, she
can usually catch him, and then eat him. Surprisingly, he often
shares her web, but keeps a safe distance.
|
BABIES
|
Sometime after mating, she constructs an egg sack.
It is water tight and strong enough to protect the young from most
predators. She guards the egg sack for days. She is a jealous
mother and rarely leaves the egg sack. When the spiderlings are
born, they must leave right away. The mother has been known to
devour her young. Even the young can devour each other.

IDENTITY
|
If you want to avoid this deadly spider, check out the
photo linked to my links page. You will be looking for a spider that
is black and shiny with a red hourglass on her underside. Her
abdomen is very round and her legs are long and elegant looking. The
male has a duller hour glass marking with red and white markings on his
back and underside. The markings aren't always prominent on the
males.
|
They live under stones, wood piles, leaves, in barns and
outbuildings. They are found all over the world but are more
common in Russia and Southeast Europe.

BROWN RECLUSE
THE BITE
|
If the bite is even felt, it might feel like a sting.
Hours later, itchy eyes and ears are noticed. The skin of the face
and upper eyelids become red and irritated. Chills, nausea, and
severe pain in the bitten extremity are common symptoms. The bite
itself becomes deep purple. It gets larger all the time because the
venom is continuously eating skin cells. It will form a crust with a
hard shell. By this time, medical help is HIGHLY advised. The
venom goes to work by killing body cells, mainly red blood cells.
This is followed by a week of prickly pain that turns into blisters.
The blisters turn into leathery scabs. The result of this is a
greenish, yellow pus oozing out of broken scabs. Other symptoms
include fever, shock, vomiting, and joint pain. The liver and
kidneys are so severely affected that death is not uncommon.38

If
professional help is notified, the doctor would cut away damaged tissue
and inject cortizone, which is a pain killer. In cases that weren't
caught right away, skin grafting and plastic surgery are highly likely.
It takes about four months for the wound to heal and a scar will always
remain.

LOCATION
|
These little monsters originated in the southern states
like Missouri, Texas, Oklahoma, and Kansas. With the settling of man
they have spread throughout the United States. They live under rocks
and ledges, warehouses, vacation homes, campers, and behind books,
furniture, in shoes, in corners, and especially in a pile of bunched up,
forgotten about clothing.

IDENTITY
|
The brown recluse is typically light brown with a dark
brown violin pattern on its back. It can reach a half inch in body
length, but a quarter inch is more common.. It's body is narrow and
its long, slender leg span can cover a half dollar. This spider also
has an extra appendage extending from the front, kind of appearing like
the neck of a violin. This pattern also gives this spider other
names like fiddle-back or violin spider.

JUST A NOTE... it is interesting to know that compared to the abundance of
the species, the actual number of bites is relatively small. It is
unfortunate that the number of bites has increased over the years.
