Nature Series: Scorpions

Scorpions are arachnids closely related to spiders, mites and ticks. Being arachnids, they have two body segments and eight legs. Scorpions also have two pincers, called pedipalps, that help them hold their prey as they eat as well as a long tail with a stinger on the tip that they use to paralyze prey. The most common scorpion in Central Texas is the striped bark scorpion. This species is yellowish-tan with two dark stripes that run along the back. Striped bark scorpions get up to 2 1/2" in length.

Scorpions are capable of stinging humans, but striped bark scorpions only cause moderate reactions to most people. Ice packs can be placed on the sting area to reduce pain and swelling. A person stung by a scorpion should be watched closely for several hours following the incident to ensure that an allergic reaction does not manifest. If breathing difficulties or hives occur, seek immediate medical attention.

To keep scorpions from moving into the home, the following techniques may be helpful:

• Remove debris (including firewood) away from the home
• Prune any trees or shrubs that touch or overhang the house
• Replace weather stripping as needed around doors or windows
• Stuff weepholes with steel wool or copper mesh
• Treat the foundation of the home with a pesticide.
  Look for active ingredients such as permethrin, cypermethrin, deltamethrin, carbaryl, propoxur
