Bark Scorpion or "Centruroides exilicauda" is one of several species of scorpions found in Nevada. The bark scorpion is one of the only species with a potentially lethal sting. Like most predators, scorpions tend to forage in distinct and separate territories and return to the same area night after night. They may enter homes when their territory has been disrupted by construction, tree removal or other disturbances.

Bark scorpions are smaller than most scorpions (1-2 inches long). The pincers are long and thin and its abdominal segments are longer and more slender than other scorpions. The color may vary from light tan to a darker golden brown. It is the only scorpion that curls its tail to the side when at rest.

Bark scorpions like to climb on and hide under the bark of trees. They are nighttime feeders found most commonly near irrigated areas, pools, in palm trees, wooden fences and on the walls in homes. Bark scorpions can climb walls and walk across ceilings. They can show up in bathtubs, sinks and beds having fallen from the ceiling. Bark scorpions are active when nighttime temperatures are above 77 degrees Fahrenheit. They are less active during the hottest part of the summer and are inactive during the winter when it is cold.

Scorpions move into yards to feed on insects attracted to lights and moisture associated with human habitation. Scorpions hide during the day and can be found around and under rocks, bark, wood piles and other debris. Extensive use of landscape rock can create excellent scorpion harborages and are important areas to inspect. It is important to remove or treat these harborages in order to reduce the scorpion population.
