There are a couple of basic habits that can prevent scorpions around or in a building: reducing clutter, storing items in plastic (not cardboard), removing yard or garage debris, and avoiding leaving items on the ground. If children are present on the property, make sure to teach them to not pick up scorpions.Consider sealing the building, and calling a scorpion control professional to inspect or perform the sealing. Spraying for scorpions is not always effective, depending on the pesticide used. If scorpion activity is suspected, a black-light can be used to find scorpions at night, as they glow in the dark when exposed to UV light. Pest control experts are trained to provide homeowners with important preventative information, and should be relied on for advice or professional help.
