How do I safely look for scorpions at night with a blacklight?
A simple approach is a consistent 10-minute perimeter sweep: start at a door, go clockwise, and keep the UV beam low along the floor/baseboard seam while pausing at corners and thresholds. A 365nm UV light typically produces the strongest fluorescence, making nighttime scans more effective without blasting the room with visible light. If you find one, use a container-and-stiff-paper method to capture it without putting hands near it, as outlined in this nighttime UV scorpion search routine.
