Yes. There are over 1,500 known species of scorpion across the world, of which about 20 live in Texas. Only only of these species is commonly found in East Texas, the striped bark scorpion, and it does live in Houston.
The striped bark scorpion is a medium-sized scorpion, usually around 2 1/2 inches in length. These scorpions are pale yellow color with two broad, darker-colored bands crossing the back and a dark triangular patch near the head.
Despite the image of scorpions as desert animals, striped bark scorpions prefer cool, moist environments. The striped bark scorpion's behavior is primarily motivated by a need to conserve the water in its body. Warm sunlight will evaporate their body water and kill them quickly. Because of this, they are almost exclusively nocturnal. They will tend to stay in cracks, crevices, and dark places, particularly where this is moisture to be found.
Scorpions are not insects, they're arthropods, so they're kind of like dangerous land lobsters. But because they are not insects, many treatments designed to work on insects will be ineffective against scorpions. Because of the danger of scorpion bites, getting professional pest control if you see scorpions in your home is usually a good idea.
