Preventing Arizona Bark Scorpion Sting

◉ Never-ever, roam around the house, or outdoors without wearing protective shoes/boots. Opting to wear sandals and slippers, is a bad idea in scorpion infested areas.

◉ Always check your shoes by shaking them and looking inside the shoe, before you wear them.

◉ Always check your clothes for hidden scorpions, as many such freak incidences have taken place in the past!

◉ Check your bathroom/toilet, especially under the sink, near the pipes, the drain and the toilet seat, for any scorpion presence. Similarly, check your kitchen as well.

◉ Never venture out at night, even while inside the house, without your UV lamp ready at hand. If there are any scorpions around, you’ll be able to see it glowing in the dark, with the help of the lamp.

◉ Protect your baby’s crib by covering with a net, that way it will mar the fall of a scorpion, that might fall off from the ceiling or curtains.

◉ These scorpions cannot climb on smooth glass, which is why you must place all the four legs of your bed, into glass fish/normal bowls. This can be done with the baby’s crib and the kid’s bed as well.

◉ Since the scorpions feed on cockroaches, centipedes etc, try to keep your home as pest free as possible. Seek the help of a professional exterminator if the need arises.

There are several risks involved, for those living in desert areas, because these harsh terrains harbor some of the world’s deadliest animals and plants. Since emergency services are more frequently available in crowded towns away from the desert, the people living closer to the desert, are at a greater danger of being harmed by venomous animals. The Arizona state health services, have ensured that no matter where you are, access to anti-venom will be provided, and is available at the nearest medical store, department or clinic.
