This thread has reminded me that I wanted to educate myself a bit about scorpions. I've only seen one in my life (Las Vegas), and it was in a little cage.
Looking around online, there seems to be quite a bit of info that educational and exterminator sites agree on, so here it is.
There are 40 varieties of scorpion in Arizona, but the most common and most toxic one is the Bark Scorpion of the American Southwest and Northern Mexico, but no deaths from it have been reported in 40 years. They are extremely sensitive to light. They can climb any surface except glass (supposedly).
Stings: If you get one, stop what you’re doing and wash it with soap and water, and then apply a cold compress. If you’re having an allergic reaction (trouble focusing eyes, random eye movements, trouble swallowing, drooling, tongue feels swollen, slurred speech, dizziness, blurry vision or muscle twitching), have someone take you to an emergency room or call 911.
Ways to eliminate scorpions:
Clear the area of tall grass, junk piles, lumber, firewood, compost piles, rock piles, wet spots. They like holes in the ground, too.
They mainly eat live insects, so if you can reduce the buffet, you will help to remove the scorpions. But they only need to eat about once a year, so they may not leave very fast.
To kill or catch them:
Burlap: They are attracted to moisture, so you can dampen burlap, lay it on the ground or floor, then stomp them, or scoop them up and take them away from where you’re living.
Boric Acid comes from Boron, a naturally-occurring mineral in the soil, and does no harm to soil or water except in excessive amounts. While this is a poison, it is a low-toxicity poison. It’s hard to eat enough to do harm w/o doing it deliberately, it isn’t absorbed through the skin, and it isn’t carcinogenic. Just keep it out of your eyes (corrosive) and don’t inhale the dust. Wash your hands after handling. I would put it on the ground around the tires, so they would have to walk through it to climb the tires.
Mouse traps, either the snapping kind, or the live-catch kind.
Glue boards - I don’t like these things, because so many other animals can be caught by them (lizards, snakes, birds, cats, etc), but if nothing else works, I would use them... carefully.
Scorpions usually move along walls, so if you’re using traps, place them there.
Natural repellents are Lavender and cedar essential oils; mix with water and spray on likely access points.
Duct Tape (it’s good for everything!): One guy uses a manual approach: He sticks a wad of duct tape on the end of an old broom handle and catches/smashes them with it. And it might be sticky enough for use as a homemade glue board, but I do think Gorilla Tape has a stickier adhesive for something like that.
And that's all I know about that.
