This scorpion was at the bottom of my neighbors pool. This is the second one they have found. What type is it and is it harmful? How do I keep them out of my yard?

Dear creeped out in Cali,
We are uncertain what species of Scorpion drowned in your neighbors pool, but perhaps one of our readers will be able to provide that information since we will be posting your letter. We do not have any advice for keeping native wildlife out of your yard. According to BugGuide: “The sting of most scorpions is not serious and usually results in localized pain, some swelling, tenderness and some discoloration. Systemic reactions to scorpion stings are rare. However, the sting of one scorpion, Centruroides exilicauda, can be fatal. Most healthy adults are not at significant risk; the ones most at risk of dying from a sting by Centruroides exilicauda are children. The site of the sting does not become discolored. Another scorpion that has been known to have an intense sting is Centruroides vittatus, but no deaths are known to have been attributed to it directly. All but one of the 25 or so dangerous scorpions are in the family Buthidae. The only other dangerous species is Hemiscorpius lepturus (Iran, Iraq, Pakistan, and Yemen) in the family Hemiscorpiidae, which has been shown to have an unusually toxic hemolytic venom.” Your specimen does not look like Centruroides exilicauda in our opinion.
