Scorpions are a serious concern in the Southwest โ particularly the Arizona Bark Scorpion, the only species in the US with potentially lethal venom. Emergency Exterminators connects you with local scorpion specialists who conduct UV light inspections (scorpions glow under UV), apply professional perimeter treatments, and seal entry points to protect your family.

Scorpion presence in the Southwest โ particularly Arizona, Nevada, New Mexico, and Southern California โ is a year-round concern requiring ongoing management rather than a one-time fix.
The only potentially lethal scorpion species in the US. Pale yellow-tan, 2-3 inches. Exceptional climber โ found on walls, ceilings, and in trees. Commonly enters homes through the smallest gaps. Found in Arizona, Nevada, New Mexico, Southern California, and parts of Texas.
Most common scorpion in Texas and the Midwest. Pale yellow with dark dorsal stripes. Painful sting but rarely life-threatening to healthy adults. Enters homes in large numbers in fall when seeking warmth.
Large (up to 6 inches), brown. Found in the Mojave and Sonoran deserts. Venom is less potent than bark scorpions. Rarely enters homes but may shelter in sheds and garages.
Scorpions entering the home โ found in shoes, under furniture, and in bathrooms. Any scorpion inside the home in Arizona or the Southwest is cause for professional perimeter treatment and entry sealing.
Scorpions in the yard and around the pool area present a sting risk during outdoor evening activity. Bark scorpions climb citrus trees and can fall from branches near pool areas.
Scorpions are exclusively nocturnal. Stepping on a scorpion in a dark room or in shoes left overnight is the most common sting situation. UV flashlight inspection at night finds scorpions you cannot see otherwise.
Catching a scorpions problem early makes treatment faster, easier, and more cost-effective.
Understanding what professional treatment involves helps you know what to expect and why it works where DIY fails.
Professional UV inspection at night finds scorpions throughout the interior and exterior. The number and locations found guide treatment focus areas.
Professional insecticide applied around the exterior foundation, under bark mulch, and in harborage areas. Provides residual protection against scorpions and their prey insects.
Crickets, roaches, and other insects are scorpion food โ eliminating prey insects reduces the food supply that sustains scorpion populations near your home.
Scorpions enter through gaps as small as 1/16 inch โ smaller than a dime. Sealing gaps around doors, windows, and utility penetrations is critical in high-scorpion-pressure areas.

For most scorpion stings from non-bark scorpion species in healthy adults: clean the sting area with soap and water, apply ice for 10-15 minutes, take an over-the-counter pain reliever, and monitor for worsening symptoms. Seek emergency care immediately for: any sting in Arizona (possible Bark Scorpion), any sting in a child under 6, any sting in an elderly person or someone with heart conditions, or any sting accompanied by difficulty breathing, muscle twitching, drooling, sweating, or blurred vision. The Poison Control number is 1-800-222-1222.
Scorpions can enter through gaps as small as 1/16 inch โ far smaller than most homeowners realize. Common entry points include: under doors without tight door sweeps, around pipes and utility penetrations, gaps in the foundation and siding, under garage door seals, and through wall cracks. The Arizona Bark Scorpion is also an exceptional climber and can enter through second-story gaps including window frames and roof penetrations. Professional entry sealing is the most important long-term control strategy.
In high-scorpion-pressure markets like Phoenix, Tucson, Las Vegas, and Albuquerque, monthly professional treatment is standard practice for households with young children, pets, or allergy concerns. The combination of heat, dry conditions, and proximity to desert habitat means scorpion pressure in these markets is year-round. Lower-pressure areas may be adequately protected with bi-monthly or quarterly treatment. Your local specialist advises on the appropriate frequency for your specific location.
The Arizona Bark Scorpion is an exceptional climber โ one of very few scorpion species that can climb smooth vertical surfaces including walls and ceilings. Finding bark scorpions on walls, in closets above floor level, in high shelves, and on ceilings is common. This is why turning on a light before entering a dark room and checking beds and clothing are important safety habits in Arizona. UV inspection of walls and ceilings at night reveals the true extent of vertical scorpion activity in your home.
