The Bark Scorpion: Why Professional Control Is Essential
Of the approximately 30 scorpion species found in Arizona alone, the bark scorpion is the primary species of medical concern and the most commonly encountered inside homes. Unlike most scorpion species that are ground-dwelling and heavy-bodied, the bark scorpion is a climber. It can scale vertical surfaces including stucco walls, tree trunks, and block fencing, travel upside down across ceilings, and access homes through incredibly small gaps around utility penetrations, under doors, and through weep holes in block construction. This climbing ability means bark scorpions are found in places most people do not associate with scorpions, including on walls, in cabinets, inside shoes, and even on ceilings where they fall onto occupants below.
Bark scorpion stings cause immediate, intense pain followed by tingling, numbness, and in significant envenomations, systemic effects including muscle twitching, difficulty swallowing, blurred vision, and in severe cases involving children or immunocompromised individuals, life-threatening respiratory distress. Any bark scorpion sting that causes symptoms beyond localized pain should be treated as a medical emergency, and antivenom is available at most hospitals in scorpion-endemic areas. This medical context makes professional scorpion control not a lifestyle convenience but a genuine safety investment.
What Attracts Scorpions to Your Property
Scorpions do not seek out human habitations for any preference inherent to the structure. They are driven by three basic needs: prey, shelter, and moisture. Understanding these drivers is the foundation of effective prevention.
- Prey availability: Scorpions eat crickets, cockroaches, beetles, ants, and other insects almost exclusively. A home with active cricket or cockroach populations is significantly more attractive to foraging scorpions. Reducing the underlying insect population through general pest control dramatically reduces scorpion pressure.
- Harborage material: Scorpions shelter under anything that provides darkness and moisture retention including stacked firewood, rock piles, landscape debris, cardboard, and dense ground-cover plants close to the home. Eliminating these harborage sites reduces the scorpion population living in close proximity to your structure.
- Moisture: In arid environments, scorpions are attracted to any source of moisture including drip irrigation emitters near the home, water features, leaking hose bibs, and even the evaporative cooler drain lines that wet the foundation area.
- Light attraction: Exterior lights attract the insects that scorpions prey on. Switching to yellow-spectrum or sodium vapor lights that do not attract flying insects reduces the prey concentration around your home that draws scorpions into your perimeter.
Our Comprehensive Scorpion Control Program
Property Assessment and Harborage Reduction
We inspect your entire property to identify all scorpion harborage sites, assess the severity of activity through night inspection using UV light which makes scorpions immediately visible, and provide specific harborage reduction recommendations that complement chemical treatment.
Perimeter and Harborage Treatment
We apply a long-residual insecticide to the entire perimeter of the structure including the foundation, block walls, patio surfaces, and all harborage areas in the yard. This treatment is applied to all horizontal and vertical surfaces scorpions traverse to contact the product during nighttime foraging.
Prey Insect Population Reduction
Cricket and cockroach control is integral to scorpion management. We treat the areas where these prey species are most active, dramatically reducing the food source that sustains the scorpion population on your property.
Exclusion and Entry Point Sealing
We identify and seal or screen all structural entry points including weep holes in block construction, gaps under doors, utility penetrations, and gaps around windows and entry doors, creating a physical barrier that prevents climbing scorpions from entering the living space.
Indoor Scorpion Safety Protocol
While treatment and exclusion dramatically reduce scorpion encounters, residents in high-pressure areas should adopt indoor safety habits that minimize the risk of accidental contact. Always shake out shoes, clothing, and towels that have been on the floor before use. Use a UV flashlight to inspect bedding before getting into bed at night, as bark scorpions glow bright green under ultraviolet light. Install door sweeps on all exterior doors. Keep beds away from walls and remove any bed skirts that touch the floor, as bark scorpions can climb bed frames. Place legs of cribs and beds in smooth-sided glass jars they cannot climb. These practices combined with our treatment program provide comprehensive protection.
