Typically, scorpions are associated with dry, desert habitats. However, scorpions can be found in a variety of areas. These include grasslands, forests, rainforests and even caves.
For over 400 million years, some form of scorpion has lived on earth. Early fossil records show that scorpions lived in the sea, as well. Virtually unchanged for much of their history, scorpions have branched out with over 1400 species worldwide.
Wherever scorpions are found, they must have a source of moisture and shade. Scorpions are nocturnal hunters, so they become active at night and will thrive in temperatures of 70 degrees Fahrenheit or above. However, they cannot retain moisture, so they must stay out of the heat. Scorpions will find places to conceal themselves during the day. Typically, they can be found in piles of wood around your home or in landscaping materials, such as bark or rocks.
Sometimes, scorpions will seek shelter inside your home. They can enter through crawlspaces or air conditioning ducts in the attic, and will find a cool place to hide. Occasionally, scorpions are found in sinks or bathtubs when they are searching for moisture.
Scorpions have also been known to burrow underground. They create a small burrow that will house them alone. Scorpions will dig deep enough to reach a cool area below the surface. They will often wait just inside their burrows to grab prey that come near the entrance.
The worldwide distribution of scorpions and their reputation for stinging have made humans fearful of them. A typical scorpion sting feels like a bee sting and will create a mild pain, with some swelling. Only 25 scorpion species are capable of causing serious harm or death to human beings.
