Scorpions

Various

Description

Scorpions are nuisance pests that are closely related to spiders, mites and ticks. There are about 1,200 scorpion species in the world and 70 species in the United States. Of these, the most dangerous species is the Arizona Bark Scorpion, which is found in the American southwest and in Northern Mexico.

Habits

Scorpions are nocturnal pests, so they hide during the day and are most active at night. They feed primarily on insects, especially crickets and cockroaches, and they also feed on spiders. However, they can survive for months without food if water is readily available.

Threats

Scorpions are known to sting as a defense mechanism or as a way to kill prey. Humans will usually experience mild symptoms that are similar to that of a bee sting, such as temporary pain, a burning sensation or localized swelling. However, there are a handful of species around the world that possess more dangerous venom, which can be potentially fatal to humans. The Arizona bark scorpion in the U.S. can deliver such fatal stings.

Color : Varies in shade from yellowish brown to tan
Shape : Segmented, long tail with stinger at the end
Size : 2-4” (20-100 mm)
Antennae : No
Region : Arid southwest and southern part of the United States

Habitat

Scorpions live in dry habitats, usually preferring deserts and semi-arid regions. Many species dig burrows in the soil and hide under rocks, logs or debris. During periods of hot weather, scorpions may enter homes through wall voids and take shelter in cool, moist areas like crawl spaces and attics.

Prevention

The key to preventing scorpions is to eliminate harborage sites around the property including woodpiles, trash and debris. Homeowners should remove stones and landscape timbers from the property, and store firewood at least twenty feet from the home and five inches up off the ground.

Since scorpions can enter structures through torn screens and holes and cracks in building exteriors, it’s equally important to seal cracks and holes on the outside of the home with caulk and repair any damaged window and door screens.
