It's that time of year here in Arizona. We practice a ritual that started when our daughter was a baby. After finding as many as 6-8 scorpions/week inside our house, we took the fight outside.
Every night or so we go out with the blacklight and the long tweezers. This is two nights worth... five scorpions. Four bark scorpions and some other type. It's interesting that the "other" scorpion is much more aggresssive than the bark scorpions - and they're the ones that do the most serious damage if they sting you. Now that we round them up outside we rarely find them inside.
For a long time our next door neighbors said they didn't have scorpions. I offered to check their backyard and found four! Now they've got their own black light.
