Scorpions glow brilliantly under UV light — making after-dark blacklight hunts one of the most effective ways to locate and eliminate them. We go where they hide, when they're most active, so you don't have to worry about finding one in your shoe.
The Arizona Bark Scorpion is the most venomous scorpion in North America. During the day, scorpions hide in cracks, crevices, under debris, and inside walls. At night, they emerge to hunt — and under a UV blacklight, they glow a brilliant blue-green, making them easy to find and treat precisely where they live.
Scorpions have a unique property: their exoskeletons contain compounds that fluoresce under ultraviolet light, causing them to glow a vivid blue-green color in the dark. This makes UV blacklight one of the most reliable ways to locate scorpions that would otherwise be completely invisible to the naked eye during a routine inspection.
Standard daytime treatments address scorpions on the move, but blacklight hunts target them in their resting and harborage spots — the places they return to every day. Treating these locations directly is far more effective than broadcast spraying alone, and dramatically reduces the active population around your home.
This service is particularly effective for Arizona Bark Scorpions, which are prone to hiding in wall crevices, under roofline gaps, in block walls, and inside attic spaces — spots that daytime inspections commonly miss.
We schedule blacklight services in the evening after dusk, when scorpions are most active and visible. Our technicians arrive equipped with professional UV blacklights and appropriate treatment materials.
We walk the entire perimeter of your home and yard under UV light — scanning walls, block fences, landscaping, eaves, and any structure on the property. Every scorpion found is logged by location so we can identify pressure zones.
Scorpions found are treated directly, and harborage areas are treated with residual products labeled for scorpion control. This targeted approach means product is applied where scorpions actually live, not just broadcast across the property.
After the hunt, we let you know how many scorpions were found, which areas had the highest concentration, and what habitat modifications (if any) could reduce future pressure. We'll recommend whether follow-up visits are warranted.
Blacklight treatments are most effective when paired with your regular Zona service. Your plan's residual barrier treatments reduce scorpion populations around the structure, while the blacklight hunt targets harborage areas directly. Together, they create a comprehensive scorpion suppression strategy.
All products used during blacklight treatments are selected for safety around children and pets. We'll advise on any re-entry intervals for treated areas, which are typically short. You won't need to evacuate — just stay clear of treated exterior areas while they dry.
Blacklight scorpion hunting is the most targeted, effective way to tackle Arizona's most feared pest — after dark, where they live.
No pressure. No obligation. Just straight answers.
