How can you avoid
scorpion stings? |
Scorpions are nocturnal animals and,
therefore, typically only emerge at night. They often hide in
dark cracks and vegetation. Ideally, accommodation should have a
ledge that is at least 20cm high to prevent entry of scorpions.
To minimize the occurrence of scorpion stings, one should:
remove loose boards, woodpiles, rocks, and debris from areas
immediately surrounding homes; wear leather gloves and exercise
caution when moving objects in yards or at campsites. When
camping, invert and shake out sleeping bags, clothes, and other
items that have been in contact with the ground, and shake out
shoes before putting them on in the morning. Always wear shoes
when walking at night. All members of the family should be able
to recognize scorpions, and everyone should be aware of the
danger they pose; special care should be taken to caution
children, and older persons who have recently moved to Arizona
from more northern latitudes. An infant's crib can be protected
by placing the legs of the crib in clean wide mouth jars.
Scorpions cannot climb clean glass.
In areas with scorpions, it is also necessary to watch out for dark
hiding places indoors: in cupboards, under the duvet and bed, or
in shoes (look under the duvet/bed and shake your shoes
thoroughly before putting them on).
Scorpions are not aggressive toward non prey, and only sting when
handled or otherwise molested. When defending themselves, they
usually hold the victim with their pincers and sting repeatedly
by thrusting the tail over the body and the stinger into the
victim's flesh. Obviously a person who has been clasped by a
scorpion should quickly remove it to avoid multiple stings.
only about 25 of the 1500 species of scorpions found worldwide
have venom deadly to humans, and only one of those, the bark
scorpion, makes its home in the United States. This species,
Centruruoides exilicauda, is most common in southern Arizona but
it also occurs in Grand Canyon, southern Nevada and southern
California. At least 30 scorpion species are desert dwellers,
including the giant desert (Hadrurus spadix), the largest at
five-plus inches, and the boreal (Paruroctonus boreus), the most
common and widespread. Baja California has the greatest variety
with over 50 species.
In some countries, it is a popular sport to 'play' with scorpions - if
you find it interesting to watch this torment, you should keep
well away from the animal.
Scorpions sting with a poisoned hook on their tail, which is
typically raised prior to an attack.
Venom from only one of the 30 species of Arizona scorpions is
considered to be life-threatening. This is the bark scorpion,
Centruroides sculpturatus (actually a synonym of C. exilicauda).
This species can be distinguished from all others in Arizona by
the following set of characteristics:
1. The chelae or pincers (on the pedipalps) of C. sculpturatus
are very slender, so that they are about six times as long as
the broadest part.
2. At the base of the stinger is a little tubercle or tooth.
This can be seen with a hand lens or with the naked eye if the
profile of the vesicle is silhouetted against a light
background.
Be careful when camping or during other outdoor activities to
make sure that a scorpion has not made a home in your clothes,
shoes or sleeping bags.
Scorpions glow brightly under UV light (black light).
Scorpions are basically immune to most pesticides. If you
suspect your house has scorpions, call a professional
exterminator.
Very few people die from scorpion stings, even the sting of the
Arizona bark scorpion. Scorpion stings are most dangerous to the
very young and the very old. Pets are also at risk.
