Lawns : Keeping the lawn mowed close to the ground and keeping landscaping plants at least 2 feet away from the house foundation. Exclusion : Recommending exclusion measures that prevent scorpions from getting inside the home. For example, your treatment plan may identify areas under doorways and openings, torn screens and areas that surround pipes and utility lines entering the house that need to be sealed. Chemicals : Using chemical products for scorpion treatment.
Scorpions prefer to hide in well-protected places, so unless the chemical applications are targeted to their harborage sites, chemical use may not always be effective. However, your pest management professional has the knowledge and experience to know which products and where they need to be applied to treat the problem. Scorpions usually become an indoor problem when they choose to leave their outdoor habitats in search of a better place to live where more food sources are found.
Scorpions commonly use gaps under doors; ground-level windows; gaps surrounding plumbing pipes and utility lines that enter the home; and cracks and gaps in the foundation to get inside a home or business. Scorpions also gain access by hitchhiking inside in boxes, firewood, potted plants and outdoor furniture. Once inside, scorpions typically seek out basements, crawl spaces, hidden places under kitchen cabinets or in garages and bathrooms.
While scorpion stings are generally nonlethal, they are venomous nevertheless. Common side effects include numbness, pain, and localized swelling. In serious cases, vomiting and breathing trouble can occur. Children and the elderly are more likely to have severe reactions from a scorpion sting. Of the numerous scorpion species found in North America, the most medially important species is the bark scorpion. Scorpions typically do not leave signs, other than visual sightings of themselves.
Scorpion concerns usually stem from the sting, which can contain venom, and not from an actual bite. No scorpion venom in the U. However, some people experience numbness and convulsions.
In extreme cases, some people may experience difficulty in breathing. Scorpions live in very dry climates. Despite this, they are very sensitive to the loss of moisture from their body and hide during the day in shady locations.
They obtain most of their water from their prey. Read more about Scorpion Habitats. Learn more about scorpion stings here. A hard, bony outer covering known as the carapace protects the cephalothorax. This covering supports a pair of median eyes at the top center. The cephalothorax is made up of the head, including the carapace, the eyes, chelicerae or the mouth, the pedipalps or the claws, and four pairs of walking legs. These claws are one of the most significant parts of the scorpion, since they are used to seize prey and defend against predators.
The opisthosoma, or the abdomen, is split into two parts, namely the mesosoma and the metasoma. The mesosoma has seven parts whereas the metasoma has five.
The first are the sexual organs, including a pair of vestigial and modified appendages that form a structure called the genital operculum. The second is the featherlike sensory organ called the pectines. The last four segments contain each pair of lungs.
All in all, the mesosoma is shielded with tergites, a chitinous plate on the upper surface, with the sternites on the lower surface. The other half of the abdomen, which is the metasoma, includes the tail. The tail has six segments, the last of which contains the anus and the stinger. Antivenins are available in areas where dangerous scorpions live. The stings from Texas scorpions produce only moderate reactions in most people because the poison has little effect on the nervous system.
A person who is stung by a scorpion should be watched closely for adverse reactions. As with any arthropod venom, allergic reactions are possible.
An ice pack applied to the affected area will relieve some pain. Scorpions have been kept as pets, but this practice is generally discouraged. Scorpions should never be kept indoors or around small children. Scorpions with even relatively low poison levels can produce fatal reactions in young children and also in adults allergic to the toxin. Scorpions are difficult to control with insecticides alone. Therefore, the first control strategy is to modify the area surrounding a structure. Naturally derived pesticides for managing scorpions include active ingredients such as rosemary oil, cinnamon oil, clove oil, thyme oil, peppermint oil, and pyrethrum.
Naturally derived products generally degrade more quickly than synthetic pesticides so they may not provide a long residual control. Synthetic pesticides for scorpion control may contain active ingredients such as permethrin, cyfluthrin, cypermethrin, lambda-cyhalothrin, deltamethrin, propoxur, carbaryl or bifenthrin. Look for products containing these active ingredients or consult a pest control operator. Apply pesticides around the foundation of the house and up to 1 foot above ground level on the exterior walls.
Also apply pesticides around doors, window eaves, and other potential points of entry. Indoor treatments should be directed at potential points of entry, corners, cracks, and crevices where scorpions hide. Follow directions on the package for dosage, mixing, and application methods.

Preferring to stay in caves, under rocks, in cacti or other crannies to stay away from the beating desert sun, this scorpion is common throughout the semi-arid regions of the Middle East and Africa. The venom is fast-acting and attacks the central nervous system, causing paralysis and, in some cases, death via respiratory failure.
If not treated with antivenin, patients can die within hours after being stung. Apart from being highly venomous, the Yellow Fattail is also a surprisingly tough little critter. If caught in a sandstorm, most other scorpions will seek refuge in any crack or crevice they can find, or even burrow in the sand, while the yellow fattail will actually stay put and allow the elements to bear down upon it. Owing to its tough exoskeleton, this tiny creature can withstand a sandblasting that can strip the paint off steel.
As with most other potentially lethal scorpions, the yellow fattail has small pincers, a thin body and relatively stout tail. It can grow to sizes of 2. In the wild, you may encounter this scorpion in the deserts of North Africa and Southeast Asia. In America, some collectors keep these as exotic pets. As of this writing, thankfully, no specimens have been reported as escaping from captivity and thriving in the wild.

Its head and body are almost entirely a darker shade of brown, or has horizontal brown bands on its plates. The pincers have dark brown-tinged tips. It can grow to a length of up to 2. The Brazilian yellow feeds on a variety of insects like crickets and roaches, and occasionally preys on small rodents if the opportunity arises.
It prefers to hide in piles of debris in houses, which makes it the culprit in many child deaths. As its name implies, this killer critter inhabits rural and urban areas of Brazil. A relative of the yellow fattail, this scorpion is very common in the deserts of the Middle East and Africa. This species was even considered a major hazard for soldiers of either side, whenever there was a conflict in the Persian Gulf.
