Scorpions are predatory arachnids recognized by their eight legs, grasping pincers, and a segmented tail tipped with a stinger. While often associated with deserts, these ancient creatures, with an evolutionary history stretching back 435 million years, have adapted to diverse environments across all continents except Antarctica. A common misunderstanding is that scorpions build “nests” in the way birds or other animals do. Instead, scorpions are generally solitary and seek out existing secluded spots for shelter, warmth, or moisture. If multiple scorpions are found in one place, it typically indicates a shared preference for that specific hiding area rather than a structured communal nest.
Scorpion Hiding Places
Scorpions seek environments that offer protection from predators and extreme temperatures, along with access to moisture. Outdoors, they commonly hide under rocks, logs, boards, and clutter. They also burrow into the soil, sometimes to depths of a meter, to find suitable moisture and temperature conditions. Some species, such as the bark scorpion, rest on vertical surfaces like trees, bushes, and walls. Around homes, scorpions are drawn to block walls and decorative rock, as these materials provide hiding spots and retain warmth after sunset.
Indoors, scorpions can enter through tiny openings in walls, floors, and foundations, often seeking cooler temperatures or water. They may be found in attics, crawl spaces, basements, and garages, often hiding in storage boxes, behind insulation, or near water heaters. Scorpions also hide in household items like shoes and clothing. Areas with excess moisture, such as around irrigation systems, leaky hoses, pool pumps, and air conditioning drip lines, are particularly attractive to scorpions during dry periods.
Identifying Scorpion Presence
Detecting scorpions in and around a home involves looking for specific indicators beyond direct sightings. One clear sign is the presence of shed exoskeletons, as scorpions periodically molt. These discarded shells are often found in hidden or dark areas. An increase in other insect activity, such as crickets, cockroaches, and ants, can also suggest scorpions are nearby, as these insects are a primary food source.
Scorpions are nocturnal. Using a blacklight can be an effective way to locate them, as their exoskeletons contain fluorescent chemicals. This property allows for easier detection during nighttime inspections.
Dealing with Scorpions
To manage scorpions around a home, a combination of prevention and safe removal methods is effective. Sealing cracks and crevices around the foundation, doors, and windows is a primary preventative measure, as scorpions can squeeze through small openings. Installing door sweeps and ensuring screens are tight-fitting and in good repair can block entry points. Reducing outdoor clutter, such as woodpiles, rocks, and debris, removes potential hiding spots.
Controlling excess moisture is also beneficial; addressing leaky pipes or standing water can make an environment less appealing. Keeping outdoor lighting to yellow or sodium vapor bulbs can help deter scorpions, as bright lights attract their prey. For removal, sticky traps can be placed along baseboards or near water sources. For significant infestations, consulting with professional pest control services is often recommended for comprehensive eradication.
