Striped Bark Scorpion

The common, striped bark scorpion has two broad, black stripes running the length of its back. Populations in the Big Bend may be only faintly marked or completely pale. The basic color of the scorpion varies from yellow to tan in adults. Immature scorpions may be lighter in color. There is a dark triangular mark on the front of the head above the eyes. In young scorpions, the base of the pedipalps and the last segment behind the abdomen is dark brown or black. This species can be easily identified by slender pedipalps (pincer-bearing arms) and the long, slender tail. The tail is longer on males than females.

The striped bark scorpion apparently mates in the fall, spring or early summer. Gestation requires about 8 months. Litter size varies from 13 to 47. The average is about 31 young per litter.

Immature scorpions molt within 3 to 7 days after birth and remain on the mother for another 3 to 7 days after that. There are five or six molts to maturity. A striped bark scorpion probably lives for approximately 4 years.

The sting of this species causes local pain and swelling. Deaths attributed to this species have not been substantiated.

The striped bark scorpion is often found under rocks, under boards and in debris. It can be found indoors or outdoors in a wide variety of habitats (pine forests in East Texas; rocky slopes, grasslands, juniper breaks in other parts of the state). Centruroides are active foragers that do not burrow. They are distinctly associated with dead vegetation, fallen logs and human dwellings. It is common for them to climb trees and walls, and many times have been found in the attics of homes. During periods of hot weather, scorpions may move into living areas to escape the high temperatures in attics.

Scorpion Stings

When handled or disturbed, scorpions can inflict a painful sting using the poison gland at the end of the tail. Avoiding their habitats helps prevent stings. The stings from Texas scorpions produce only moderate reactions in most people because the poison has little affect on the nervous system. However, a person who is stung by a scorpion should be watched closely for adverse reactions. An ice pack applied to the affected area will relieve some pain. If swelling and/or pain persists or if breathing difficulties occur, immediate medical attention is necessary.

Scorpions as Pets

Scorpions have been kept as pets, but this practice is strongly 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.

Control

Scorpions are difficult to control with insecticides alone. Therefore, the first control strategy is to modify the area surrounding a house.

• Remove all trash, logs, boards, stones, bricks and other objects from around the home.
• Keep grass closely mowed near the home. Prune bushes and overhanging tree branches away from the house. Tree branches can provide a path to the roof for scorpions.
• Store garbage containers in a frame that allows them to rest above ground level.
• Never bring firewood inside the house unless it is placed directly on the fire.
•Install weather-stripping around loose fitting doors and windows.
• Plug weep holes in brick veneer homes with steel wool, pieces of nylon scouring pad or small squares of screen wire.
•Caulk around roof eaves, pipes and any other cracks into the home.
• Keep window screens in good repair. Make sure they fit tightly in the window frame.
