Common in the Southern U.S., scorpions are large (1 to 3 inches long), eight-legged arachnids with a segmented body, claws and a long, venomous tail. They have poor eyesight and use their claws to help them navigate, as well as to seize prey (other insects) and defend themselves. Because they live in hot, dry climates, scorpions are most active at night and seek protected areas during the day. While a scorpion’s sting is usually not considered harmful, in rare cases it can lead to a deadly allergic reaction. To prevent scorpions from entering the home, make sure all screens, outside doorways and cracks are properly sealed. Remove boards, firewood, rocks and other debris from next to the house. Examine all firewood before you bring it inside. If you are stung by a scorpion, seek immediate medical attention.
