Scorpions

Description

Scorpions are close relatives of spiders, ticks and mites. They have broad, flat bodies with eight legs. They are most easily identified by their two pincer-like “crab legs” at the front of their bodies and four pairs of legs followed by the six-segmented stinger-tipped tail at the back. Scorpions can range in color, depending on species, from the mustard yellow of the deadly sculptured scorpion to the black of the black scorpion. Most are striped brown or tan.

Biology

Scorpions are most commonly found in warmer parts of the country, particularly in the South and desert areas of the Southwest. They are frequently found under stones, in piles of rocks or masonry, in piles of wood and under tree bark. They are often found in crawl spaces, attics or in dry stone walls or foundations. They may invade homes in search of moisture and are most likely found in washrooms, bathrooms, closets, garments, shoes or bedding.

Scorpions are poisonous; the poison glands are in the last segment of the tail. All scorpions produce a painful sting. Most species are not dangerous but the deadly sculptured scorpion, common in Arizona, has been responsible for many deaths. All stings should be promptly treated by a physician especially when small children are involved.

The mother scorpion produces an average of 30 living young per brood which she carries on her back for up to 15 days. It takes up to four years for most species to reach maturity. Scorpions are predators, feeding mainly on insects and spiders. They can survive without feeding for many months.

Control of Scorpions

Sanitation is the first step in scorpion control. Loose boards, wood piles, rocks, and debris should be eliminated from areas around the home, especially near foundation walls. Spray an excellent residual insecticide in these areas. This will also reduce populations of insects that the scorpions feed on. Spray a swath outside approximately six feet around the perimeter of the home and one foot up the foundation wall. Spray all entry points from the inside. We recommend using Suspend SC. Use a Chapin pump-up type sprayer for application. Both are excellent insecticides. Use Delta Dust to treat the electrical outlets, attic spaces and around the plumbing and electrical fixtures. Use a Hand Duster for application of the dust. Always wear Gloves and a Dust mask. Scorpion infestations can be effectively controlled with thorough applications of the above insecticides into cracks and crevices and other potential harborage areas.
