They are armed predators that come out at night and like to sneak into your home.
Many of us moving into the outskirts of Tucson, into open desert are finding company-- with a sting-- scorpions.
The Bark Scorpion is the one homeowners are most likely to encounter, 99-percent of the time, according to Stephan Poulin of the Arizona Sonora Desert Museum.
The Bark Scorpion gets its name because it favors climbing on mesquite trees, and it can climb the wall of your home.
It's small, about the size of a pinky fingertip fully grown, but its sting packs a wallop.
"Pins and needles," explains Poulin. "It's not something I'd want to experience again."
Poulin received his greeting from a bark scorpion after he picked up a Desert Tortoise.
The creature was hanging on the underside and stung his finger when he inadvertently squeezed it.
The bark scorpion likes to squeeze through cracks and crevices.
A good rule of thumb-- if you can fit a credit card into the crack, a scorpion can get through.
Homeowners are likely to encounter them if they live in Oro Valley or Marana, with zip codes 85737, 85739, and 85742, typically around newly developed areas.
Scorpions are also easy to find near the Tucson Mountains, at zip code 85735, in the Catalina Foothills, 85718, 85750, or 85749, and to the southeast, in Rita Ranch, Vail, and Corona de Tucson, 85747 and 85741.
Experts say if you're stung, put ice on the affected area. If irritation persists or additional side effects occur, call 911 and get to the hospital.
The sting from a Bark Scorpion can be very dangerous to people with medical conditions, infants and the elderly.
An LED UV light can help you spot them glowing in the night, and if you have barbeque tongs and a bucket, you can pick them up around your yard.
