Scorpions live in very dry climates. Despite this, they are very sensitive to the loss of moisture from their body and hide during the day in shady locations. They obtain most of their water from their prey.
Scorpions use their sting to capture prey and to defend themselves. They hunt at night and will not sting unless provoked or they feel threatened. All scorpions use their stings as a defense mechanism or a weapon to incapacitate prey. But the potency to humans of stings varies, depending on the scorpion species. One thing that all scorpions have in common is that the sting possesses venom, which usually is neurotoxic in nature.
Most scorpion sting symptoms are mildly painful and involve numbness, tingling and swelling around the sting site. More severe symptoms include muscle twitching, unusual head, neck and eye movements, drooling, sweating, vomiting, high blood pressure (hypertension), low blood pressure (hypotension), accelerated heart rate, restlessness or excitability. Stings can cause immediate pain or burning, and produce small swellings that are sensitive to the touch.
Symptoms of Bark Scorpion stings result in numbness or tingling, blurry vision and twitching muscles. For children, hyperactivity and erratic eye movement can manifest.
Signs of an Infestation
Scorpions typically do not leave signs, other than visual sightings of themselves.
When scorpions become a problem, the property owner should contact their pest management professional for advice and assistance. Your pest management professional will inspect your property, plus provide services and recommendations that will address what is needed to minimize scorpion problems. Some of the things your treatment plan may include are:
Providing services or making recommendations for how to reduce the scorpions on your property based on your pest management professional’s inspection findings. This normally includes efforts to reduce the environmental conditions that support scorpion populations, and if needed, an insecticide application to areas where scorpions are found or where they could enter the home.
Removing debris from around the house where scorpions like to live. Typical scorpion habitat includes areas that provide protection such as under rocks, fallen trees, debris, stacks of firewood, potted plants, outdoor furniture and inside attics, crawl spaces and outdoor storage sheds or barns.
Keeping the lawn mowed close to the ground and keeping landscaping plants at least 2 feet away from the house foundation.
Recommending exclusion measures that prevent scorpions from getting inside the home. For example, your treatment plan may identify areas under doorways and openings, torn screens and areas that surround pipes and utility lines entering the house that need to be sealed.
Inspecting items to ensure scorpions are not accidentally being moved inside the home. Some common recommendations include checking to ensure scorpions are not in firewood or boxes brought inside from outside storage areas.
Using chemical products for scorpion treatment. Scorpions prefer to hide in well-protected places, so unless the chemical applications are targeted to their harborage sites, chemical use may not always be effective. However, your pest management professional has the knowledge and experience to know which products and where they need to be applied to treat the problem.
