Scorpions, ancient arachnids with a distinctive appearance and venomous sting, often inspire caution. While masters of concealment during daylight, a unique biological feature makes them easy to spot at night. Using a special light source, enthusiasts and homeowners can effectively locate these creatures.
Understanding Scorpion Nocturnal Behavior
Scorpions are primarily nocturnal, an adaptation that helps them thrive in often arid environments. They emerge at night to avoid the intense daytime heat and to hunt for prey. This nocturnal activity pattern allows them to conserve moisture, as moving during cooler hours reduces water loss through their exoskeleton.
During the day, scorpions hide in cool, dark, and often humid places. These hiding spots include burrows, under rocks, logs, loose bark, or debris. They also seek shelter in human-made structures like sheds, garages, and within homes, in cracks, crevices, or under objects.
Essential Equipment for Night Searches
To effectively locate scorpions at night, a UV (ultraviolet) or “black” light is essential. Scorpions possess compounds in their exoskeleton, specifically beta-carbolines, that absorb UV light and re-emit it as a vibrant blue-green glow. A UV flashlight with a wavelength around 365 to 400 nanometers is effective for this purpose.
Beyond the UV light, protective gear is essential for safety. Sturdy closed-toe shoes and thick gloves provide protection against stings or scrapes. Tongs can be useful for safely moving debris or relocating scorpions, though direct handling should be avoided.
Effective Search Techniques
Conducting a successful night search requires methodical effort. Begin by scanning outdoor areas around your home, focusing on perimeter walls, foundations, and dense vegetation. Woodpiles, decorative rocks, and other landscape features are also prime spots where scorpions might emerge.
Inside the home, direct the UV light along baseboards, into closets, and under furniture. Scorpions seek shelter in undisturbed, dark locations, including shoes or laundry piles. Move slowly, sweeping the UV light across surfaces to detect the glowing outline of a scorpion. The fluorescence makes them stand out against their surroundings.
Safety During Scorpion Searches
Safety is essential when searching for scorpions. Always wear long pants and closed-toe shoes to protect your skin from accidental contact. Avoid direct handling of scorpions, even if they appear docile, as their sting is a defensive mechanism.
If a scorpion is found, observe it from a safe distance. For removal, tongs can be used to gently pick up the scorpion and place it into a container for relocation. If stung, clean the affected area with soap and water and apply a cool compress to reduce pain and swelling. While most scorpion stings are painful but not life-threatening, seek medical attention immediately if severe symptoms like difficulty breathing or widespread swelling occur.
