Generally speaking, scorpions are drawn to dry areas, and their main sources of food are usually small insects such as crickets and spiders. Keeping your home free of these insects will make it much less likely that scorpions will be a problem, so general pest control is always advisable. If they do get into your home, they are usually found in secluded dry areas such as closets and garages. They have also been known to hide in piles of clothes, particularly ones that have not been moved recently. Eliminating these hiding spaces will go a long way in making your other control efforts more effective.
