Pestgon FactSheet


SCORPION (Scorpiones)

Description:
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.

Biology:
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. One may occasionally wander in to a building but their normal habitat is outside.

Economic Impact:
Although scorpions can inflict a painful sting to the unwary bare foot, they are generally considered a beneficial creature,. The venom of scorpions indiginous to Southern California is similar to a bee sting and can be of concern to those who may be allergic to their venom. On rare occasions their population may erupt in unusually large numbers, which may call for special pest control procedures.

Management Methods:
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.
