Okay. One of my daughters has a house in Austin (wooded area), and has to chase scorpions off her deck (as well as tarantulas which are a lesser concern). When I last visited, a tarantula walked around my feet in the driveway, which was interesting. If it was a scorpion, I would have jumped away.
My late step-daughter had a house in San Marcos (fairly near Austin) that was on a country road in a sparsely populated area. While sitting outside on her porch, scorpions were a common sight. I suppose that the areas outside Houston in wooded areas, like The Woodlands probably have their share as well. I have never seen one in Houston proper or in the Sugar Land area where I live.
