Identification: The 3 Most Common Types of Scorpions 

Before you can treat for scorpions, it is helpful to know which species are infesting a home or property. Here are the three most common species that threaten US homes:

Arizona Bark Scorpion

Bark Scorpion

Arizona Bark scorpions are considered the most venomous scorpions in North America, with the number of Bark scorpion sting victims in Arizona alone estimated to be in the thousands each year. These scorpions measure an inch to inch and a half in length, and are a pale yellow in color.

Striped Bark Scorpion

Striped Scorpion

The Striped Bark scorpion is the most widespread scorpion in the United States. The scorpion is a smaller species of scorpion, measuring a total body length of 1 to 1.5 inches. This species has a powerful sting, which often results in pain comparable to that of a wasp; that can last for several hours. They are distinguished by their orangish brown color, and the black striped that run vertically down its back.

Striped-Tailed (Wood) Scorpion

The Striped-Tailed Scorpion is sometimes referred to as the Arizona devil scorpion or Wood scorpion. These scorpions measure about two inches in length, are a tan to dark brown in color, and are a little thicker or stockier than the bark scorpions. They infest homes in Arizona, California, New Mexico, and Mexico.

*** Note *** Desert Hairy scorpions are also commonly found in the Southwestern U.S., but these scorpions rarely infest homes to the extent of the above mentioned.

Integrated Pest Management For Scorpions 

Proper Integrated Pest Management for scorpions includes five important steps: 1) Inspection (thorough approach is needed), 2) Identification (have tools and resources available), 3) Assessment (putting together a plan), 4) Remedial Tactics (executing your plan), 5) Evaluation (did it work?).

After an inspection, and properly identifying the species of scorpion you’re dealing with, it’s time to put together and execute a plan.

Here’s a plan that should be followed to best manage a scorpion infestation:

Habitat Modification

Habitat modification is crucial when it comes to scorpion management. Remove trash, logs, stones, bricks, firewood, etc. from around an infested property. Never store firewood inside or directly adjacent to structure.

Caulking windowTrim branches away from the home, and mow grass or weeds near the foundation. Tree branches can provide a path to a home for scorpions. Installing weather stripping around all doors and windows will help keep the little buggers out. Plugging holes and entry ways into a property with copper wool, nylon pads, foam or wire screen will also help keep them out; as will caulking around all pipes, eaves, and other cracks found around the home or property.

You should also store garbage containers in a frame that allows them to rest above ground level.

Remedial Tactics To Control Scorpions

Mechanical Controls 

Manually removing or killing the scorpions you see is a start. When you see a live scorpion, safely and carefully squash it. Vacuuming is also effective; given you have a way to kill them after sucking them up. A shop-vac filled with a solution of water and vinegar should suffice. Sticky boards or glue traps are also effective in areas of high scorpion traffic. The habitat modification method mentioned above is also an effective mechanical control that can be used to eliminate scorpions.

Pesticides For Scorpions 

Pesticides can be very effective when it comes to managing scorpion populations for two reasons. First, pesticides will kill the roaches, beetles, crickets, and other insects that scorpions like to eat. Without an abundant supply of food, scorpions will have less interest in a home or property.

Second, there are also some pesticides that are effective at exterminating scorpions. Microencapsulated (ME or CS), Suspension Concentrates (SC) and wettable powders (WP) can provide longer residuals, and sit up on surfaces for better scorpion interaction.

A few effective pesticides for scorpions are as follows:

ALPINE DUST applied with a hand duster into cracks and voids at the equivalent rate of 10 g / sq. m.

CYHALOCAP CS and Temprid SC applied by broadcast; mixed at 1 gal / 1000 sq. ft.
