There are approximately 25 scorpion species of danger to humans. Their venom contains neurotoxins and enzyme inhibitors. The most dangerous in the U.S. is the bark scorpion. Most other deadly species live in Asia and Africa.
Get Rid of Scorpions
The lesser brown scorpion makes its home in tropical regions like Hawaii. It has standard scorpion biology and is a nocturnal hunter. This species uses its tail to repeatedly sting prey and predator for quick victory.
The Arizona bark scorpion is the deadliest in North America. Its less than 3 inches and found in deserts. They can climb and remain upside down under structures. Their neurotoxins can lead to immobilization and fatality.
Scorpions vary in size from 4 centimeters to 21 centimeters. Size doesn’t seem to depend on environment or lethalness. Some of the smaller scorpions, of the Buthidae family, are the most venomous and dangerous to humans.
Scorpions have two body segments: head and abdomen. These contain all essential anatomy to function. Attached to the abdomen is the tail. It carries the reputed stinger and venom sac used for neutralizing prey and predator.
Whip scorpions are unique from true scorpions. They are arachnids but have long, thin tails – without a stinger or venom – that spray acetic acid. Females lay eggs instead of a live birth. They are nocturnal hunters.
The tailless whip scorpion is very unique. They have no tail or stinger and the front legs are long, thin “whips” used as sensors. Their look and movement resemble crabs. Females care for young as do others scorpion species.
Pseudoscorpions measure 2-8 millimeters in length and have neither tail nor stinger. Their primary diet is arthropods. They will make their way indoors but are no danger to humans. Most of the species lives in the tropics.
The blue scorpion is found throughout the Western hemisphere. Its able to mingle with other scorpions. Like other scorpions, it is a nocturnal hunter and preys on insects. Their venom is thought by some to help treat cancer.
All scorpions have segmented bodies, eight legs, front pincers, and are nocturnal hunters. Most species have a curved tail with stinger. Many scorpions aren’t harmful to humans, but identification if stung is important.
A scorpions venom contains neurotoxins which affect the victims nervous system. If stung, a person should apply cold compress to the area for 10 mins., remove it for the same, and repeat. Keep watch for other symptoms.
The emporer scorpion can grow to an impressive 8 inches long. Found in the tropical forests of Africa, it uses very strong pincers to hunt prey. The sting from an emporer scopion is mild. They are very popular as pets.
A scorpions stinger is a weapon against prey and predators. It is at the end of the tail with a venom secreting gland. They can sting multiple times paralyzing the victim. Some release deadly neurotoxins.
Scorpion stings vary in severity. Most are harmless and equate to a bee sting. The most serious inject neurotoxins which cause serious symptoms including death. The venom is being studied for combating other human diseases.
Scorpions don’t bite. They sting with their tail. These can be painful but are rarely fatal. Neurotoxins released by many species cause various reactions. If stung, wash the wound site thoroughly and apply a cold compress.
Desert scorpions are the most common worldwide and the most deadly to humans. They are mostly light in color to blend with their surroundings. These are nocturnal arachnids that hunt mostly insects as prey.
The black scorpion is aggressive, territorial, and resides in the forest of Thailand, Malaysia, and Singapore. They are large and have strong pincers to hold prey. They mainly eat insects and stings are not fatal to humans.
There are over 1500 scorpion species worldwide. Smaller scorpions trend as more dangerous from deadly neurotoxins injected by their stings. One type living in caves has no eyes, and the whip scorpion has no tail or stinger.
There are many different species of scorpion all over the world. Some inhabit cold climates, but most exist in tropical, subtropical, and desert regions. Only a few are fatal to humans including the bark scorpion in the U.S..
Red scorpion body and legs have a reddish-orange color. Their sting is one of the deadliest to humans. They are the smallest scorpions and surprisingly common. The victim of a sting usually dies within three hours.
Sand scorpions reside in the desert regions of the U.S. and Mexico. They feed on all sized insects and spiders. Vibrations in the sand alert them to others’ presence. These are nocturnal hunters with very strong front claws.
Scorpion larvae are unique even within the arachnid class. Females carry eggs inside them. The young hatch and immediately climb on their mothers back. They remain until the first molt and then disperse.
Scorpions live in all type environments. They prefer warm weather but are unable to retain moisture. This forces them out of daytime sun and near water sources. Some scorpions burrow or make their way indoors for survival.
If threatened, a scorpion will strike but most species are relatively harmless. Only 25 of the 1400 produce venom dangerous to humans. They do kill pests. Scorpions hide outdoors in wood and debris piles and indoors in shoes.
Scorpions feed on insects, centipedes, spiders, other scorpions, and, larger ones, vertibrates. Their food must be in a liquid form to digest. Most are nocturnal hunters and use hairs on their legs to sense prey.
The scorpion lifecycle lasts for several years and encompasses multiple stages. Females carry the newly birthed, around 35, on their backs through the first molt. Molting occurs a number of times before becoming adults.
Scorpions are arachnids, same as spiders. They have eight legs, two pincers, and an erect tail with stinger to immobilize prey. Their bodies cannot hold water, so they are nocturnal hunters. Insects are their main fare.
Prevention is the best method to keep rodents out of a house. Ensure all openings to the outside are sealed with proper materials. Keep counters clean, food properly stored, trash sealed, and all of it away from the ground.
Termites can devastate a home. They feed on the products used in construction. Signs of damage are hollowed wood, mud tunnels at the foundation, piles of wings or swarms, blistered paint, and minimal water damage on walls.
The first step in controlling bedbugs is finding their hideout. Once located, a plan of action can be enacted. High heat, inescticides, and powders are all good at eliminating bedbugs. Consult a pest control expert for help.
