Pest description and damage Scorpions in the Pacific Northwest are not dangerous except to people who are hypersensitive. The sting is similar to that of a yellow jacket. Control often can be accomplished by removing hiding places (debris) from around buildings. Outdoors, eliminate hiding places from around the house, such as debris, trash, lumber, and wood and rock piles. Close entry points to structures. Reduce accumulation of moisture: provide run-off areas for rain water and use gravel rather than organic mulches adjacent to the building foundation. During dry weather, scorpions can be trapped by spreading wet burlap bags around buildings. Exterior application of a pesticide registered for scorpion control may be appropriate.
