Scorpion Control and How to Get Rid of Scorpions
General Scorpion Information
Scorpions are arachnids. The are a close relatives of ticks, mites and spiders. There are approximately 1,300 species of scorpions worldwide. They are characterized by an elongated body and a segmented tail that is tipped with a venomous stinger. Scorpions are very common in the Southern and Southwestern United States. Most scorpions in the United States are not poisonous, except for two species found in the southwestern states of Arizona, California, New Mexico, and Texas. Scorpions are commonly thought of as desert animals, but in fact, they inhabit many other habitats as well. These include grasslands and savannahs, deciduous forests, pine forests, rain forest and caves.
Most of the scorpions that enter dwellings are not poisonous, their sting is similar to bees or wasps. It's usually better to assume that they are poisonous if you are unsure.
Scorpions have a long slender body with a 5-segmented tail that can be arched over the back.
Size varies between the various scorpion species, but most measure about 2 inches when fully grown. Their colors range between yellow, blue, reddish brown and black.
Striped Back Scorpions
A typical non poisonous scorpion is the common striped Centruroides vittatus, striped back scorpion.This species is widely distributed in the southern United States. It has 2 broad, dark bands extending the length of the back, on an otherwise yellowish-brown body.
However, certain species in the desert Southwest can be poisonous.
The US species, Centruroides exilicauda , (Bark Scorpion-pale yellow in color)is found over much of the Southwest.
Also known as the bark scorpion, they are pale and small, making them extremely difficult to see.

- Scorpions are nocturnal, predatory animals that feed on a variety of insects, spiders, centipedes, and other scorpions.
- The larger scorpions occasionally feed on vertebrates, such as smaller lizards, snakes, and mice. They locate prey primarily by sensing vibrations.
- Although scorpions are equipped with venom to defend themselves, scorpions fall prey to many types of creatures, such as centipedes, tarantulas, insectivorous lizards, birds (especially owls), and mammals (including shrews, grasshopper mice, bats).
- Scorpions feed mainly on insects and spiders and can survive without feeding for six months.
- During the day scorpions hide under stones, in piles of rocks, in cracks in masonry, in wood piles and under the bark of trees.
- Scorpions enter structures seeking water and shelter.
- Inspection for the scorpions is made easy with the
UV Tracker Light
This tracking tool has 14 Ultra Violet LEDs for a powerful flashlight that will illuminate scorpions as well as fluoresce rodent and cat urine, making detection easier.
Recommended Measures for Scorpion Control
Remove outdoor harborages e.g. piles of trash, stones, boards,
firewood on the ground and the landscape timbers.
Points of entry into buildings, e.g. siding, windows, doors, pipes and wires, should be
- Residual Insecticide Usage: The use of a residual insecticide such as wettable powders (WP) or an encapsulated product, like Lambdastar Ultracap 9.7. They should be applied as a 3 to 10 foot band around the perimeter of the structure, into harborage sites, and/or around potential entry points, such as: around all windows and doors, along baseboards, plumbing, inside closets, and garage and basement areas. Both Demon WP and Cyper WSP are wettable powders, that may leave a visible residue that can be seen against dark surfaces.
- Dust Usage: Insecticide dusts should be used in the attic area if that is source of entry.You may apply an insecticide Dust such as D-Fense Dust or Drione Dust with a duster. This dust would be useful in cracks and crevices, wall voids, electrical fittings, around doors and window frames, etc. A convenient duster for dusting the attic area is a garden duster like the Dustin Mizer. It holds one pound of dust that you are able to crank out easily.
Recommended residual sprays
Lambdastar Ultracap 9.7
LambdaStar Ultracap 9.7 (Broader label and longer lasting-may be used inside or outside and will dry invisible. Lambdastar Ultracap has no smell. LambdaStar Ultracap will last longer outside and adhere to the surface better due to its encapuslated technology. It will yield 20-40 gallons
Cyper WSP and Demon WP have the same label, but Cyper WSP is more economical.
