Scorpions are eight legged venomous invertebrates and are related to spiders
and ticks, which are Arachnids. They possess an extended, broad flattened,
body and a segmented, erectile tail, ending with a venomous stinger. They
have large and powerful pincers that are used to grasp and subdue prey. Most
adult species in southern California are between 2 and 3 inches long and
their colors range from yellowish-brown to black.
Scorpions do not usually attack man unless directly or accidentally provoked.
They are generally nocturnal, predatory animals that feed on a variety of
insects, spiders, centipedes, and other scorpions and earthworms. In the
commercial landscape environment, scorpions seek cover under rocks and debris.

Scorpions are generally considered a beneficial creature and are therefore
of little economic concern. The greatest concern economically, involves public
and tenant relations because scorpions scare many who may observe them. On
rare occasions their population may erupt in to unusually large numbers,
which may call for special pest control procedures.
In case of an infestation, the first control strategy is to modify the area
surrounding the buildings. Sanitation is the first and most important step
in scorpion control. Cardboard boxes, boards, rocks, and debris should be
eliminated around and near foundation walls. The use of insecticides for
scorpions is usually a last resort.
