What the sources say

Venom: “The most common species found in Oklahoma is about two inches long. … The venom can produce considerable pain around the area of the sting, but swelling is generally limited. … The sting of the species of scorpion we have in Oklahoma is not considered to be lethal and rarely causes few problems.” (Oklahoma Cooperative Extension Service, Oklahoma State University)

Habitat: Scorpions generally hide during the day and are active at night. They tend to live under boards, stones, or other objects; or beneath loose bark on trees and logs. (Oklahoma State University Extension)
