How to Get Rid of Scorpions

Scorpions are some of the oldest known groups of arthropods still around. They prefer to remain hidden the duration of their life, resting under soft soil or rocks and other items laying on the ground. They are usually divided into 2 subgroups, burrowing and non-burrowing. Burrowing scorpions are known for elevating their tail over their body, while the tail of non-burrowing scorpions is positioned horizontally, parallel to the body. The scorpion sting is mildly painful and its intensity is often compared to that of a bee sting. Of over the 90 species that occur in the United States, the Bark Scorpion is considered to be the most dangerous.

Get Rid of Scorpions

Scorpion activity increases in the western hemisphere of the United States, around and towards the major desert cities. Many homes out west lack grassy lawns and instead use river rock for landscaping, accommodating the natural habitate of a scorpion. Many brick homes out west are equipped with weep holes, tiny holes that allow moisture to escape from the inner portions of walls. While these holes are necessary for the regulation of moisture throughout a home, they make excellent points of entry for scorpions and other insects. They may also enter homes through poorly sealed doors and windows. Once inside, the scorpion will seek a poorly lit area, taking shelter beneath a couch, inside of a cabinet void, or inside of your walls.

Scorpion Control

Because scorpions are most active at night, it's better to treat the property at sunset. Dust based products like DeltaDust are preferred and should be applied to cracks and crevices in areas with suspected activity. Wall and plumbing voids should also be treated, with special attention paid to areas that are higher in moisture, like kitchens and bathrooms. Perimeter treatments should focus on entrance points, like doors, windows, and weep holes.

  • Conduct any and all treatments at nightfall. Scorpions will glow when exposed to a black light.
  • Suspend SC is the best product for scorpions. Any pesticide labeled for scorpions should work just fine, but Suspend has a 30 day residual. Glue boards can also be strategically placed in areas of high activity.
  • Exclusion, exclusion, exclusion. A properly sealed home will rarely get pests. Focus on sealing any and all cracks and crevices, including windows, dryer vents, faucets, doors, etc.

While environmental modification is encouraged, it’s not always necessary. The elimination of hiding spots does wonders for scorpion control, but the advent of residual pesticides will help limit the work load. Weep holes should be sealed with steel wool so moisture is still allowed to escape, as well as treating around any plant drips (desert cities only). Caulking around suspected points of entry and ensuring that all windows are properly sealed and screened will greatly improve the reduction of activity.

Scorpion Stings

Like spiders, people are most often stung when a scorpion is trapped between clothing or bedding and cannot escape. Glass jars can be placed on the legs of cribs to prevent babies from being stung. While not particularly aggressive, they will sting if provoked and can easily be scooped up using a thin sheet of paper and a jar. Alcohol and sedatives should be avoided if stung. As with any pest, a large portion of emergencies stem from a preexisting allergic condition, where small children and the elderly are at most risk. The Bark Scorpion, Centuroides vittatus, is a very common and dangerous species.
