SPIDERS

snakes, and ticks**
While it is a good idea to leave all wildlife alone,
there are some that should be especially weary of.
Spiders, ticks and snakes are of particular concern
Black Widow and the Brown Recluse are the spiders are
found in
The Black widow is most noted for the brightly
colored hour-glass marking on the abdomen, but not all species have this
marking.
This spider's bite is much
feared because its venom is reported to be 15 times stronger than a
rattlesnake's. In humans, bites affect the body neurologically, and produce
muscle aches, nausea, and a paralysis of the diaphragm that can make
breathing difficult; however, contrary to popular belief, most people who
are bitten suffer no serious damage—let alone death. But bites can be
fatal—usually to small children, the elderly, or the infirm. Fortunately,
fatalities are fairly rare; the spiders are nonaggressive and bite only in
self-defense, such as when someone accidentally sits on them.


TThe
treatment for the bite of a black widow should require immediate transport
to the hospital. It will be a
physician’s decision to treat the patient by letting the patient “ride out”
the poison or administer antivenin.
(If treated with antivenin, a person’s information is downloaded to a
national database. Because of
the difficulty to produce the antivenin, a person can only receive this
treatment once in their lifetime.)
The recluse spider or violin spider is approx. ¼ - ½
inches long. The color is
generally brown. Its body shows a peculiar head with a dark brown
violin-shaped spot; the legs are light brown and the oval-shaped abdomen is
dark brown, yellow, or greenish yellow. The most important characteristic is
the presence of 3 pairs of eyes. Normally, all spiders have 4 pairs (8
altogether).


The spider has
a powerful poison and if bitten will cause physiological damage.
The bite will cause skin lesions and sometimes more common symptoms.
These symptoms depend on the amount of the poison and the sensitivity of
each individual. Initially, the bite is painless to such an extent that the
victim is completely unaware of it, but soon it begins to become evident
after a few hours with a variety of symptoms.
The poison causes the necrosis (death) of the soft tissue that starts as a
local inflammation with
reddening,
hard swelling and pain.
General symptoms are:
fever,
shivering, nausea, vomits, itching, restlessness and state of shock.
The injury is usually of 1 to 2 3/4 inches and it becomes evident with the
appearance of an ulcer, which can take several months to heal and generally
leaves unattractive scars.
The specific
antidote for the Brown Recluse Spider is not available yet.
Immediate hospital care is needed.
If left untreated, (worst case) the victim will develop an infected
necrotic ulcer that will only worsen.
It can leave a severe deformity, and plastic surgery/skin grafting
may be necessary for the affected area to be healed.
There are some preventative measures to avoid the
unpleasantness of a poison spider bite when reenactor camping.
Don’t stick your hands in dark places and wear gloves when rummaging
through brush or picking up sticks and logs for a campfire. Be aware of
where you are sitting, especially around the campfire.
You’ll know instantly if you’ve been bitten by a black widow, but it
may be a few hours before you feel the affects of a brown recluse bite.
Check your tent and bedding before bunking down for the night, and shake
your boots and brogans before you put them on.
