Physical Appearance

The scorpion is an arachnid and has eight legs. This invertebrate is closely related to spiders, mites, and ticks. Other characteristics include:

  • elongated body and segmented tail with a stinger on the end
  • tail usually arches up over the back
  • average length is about 2 inches
  • color varies widely; may include reddish brown, blue, yellow, and black=

Behavior & Habitat

Scorpions easily adapt to a wide range of conditions and habitats. There are about 90 species of scorpions found in the US, with all except four of them occurring west of the Mississippi. Scorpions are most prevalent in southern Arizona and parts of Oklahoma and Texas. Scorpions are active only at night, remaining hidden within tight cracks and crevices during the day.

Feeding Habits

Scorpions are predators that hunt and feed primarily at night. The preferred scorpion entrée includes a variety of insects such as spiders, centipedes, and other scorpions. Larger scorpions may also feed on vertebrates such as smaller lizards, snakes, and mice.

Life Cycle

After a unique mating ritual, the male scorpion is typically eaten by the female. Gestation period may last between several months to a year and a half, depending on the species. An egg sac may contain 25 to 35 young. Scorpions molt about 6 times before becoming reproductive adults, a process that may take 1 to 6 years. The average scorpion lives 3 to 5 years, although some species may live as long as 10 to 15 years.


  • Scorpions are a nuisance in domestic settings for several reasons. The main reason is that scorpions will sting when disturbed. A sting may range from painful to deadly, depending on the species, but most species are not poisonous. If you are stung by a scorpion, you should always contact a physician.
  • Scorpions are also a real pain to get rid of. Pesticides are not always effective on adult scorpions, and when they do work, they do very slowly because the cuticle (or, outer covering) of the scorpion is so thick.

General Prevention & Control :

  • Trim branches and shrubbery away from the home and roof to prevent entry.
  • Insert weather-stripping around doors and windows.
  • Do not store firewood in the home; bring in only that which is immediately to be used.
  • Caulk or repair cracks and crevices that may become points of entry.
  • Inject Delta Dust into wall voids, crawls spaces, and cracks and crevices with a hand duster.
  • Spray a residual around the indoor perimeter of baseboards with Suspend or Talstar One on a low pressure setting, using a 2 gallon sprayer.
  • Treat outdoor perimeters with a 6 to 8 foot band of Talstar One using a 2 gallon sprayer.
