A thorough inspection and integrated approach is required for scorpion control.  Scorpions are hardy creatures and pesticide applications only are not likely to eliminate their presence in or around a structure.  Sanitation is a key element in reducing the likelihood of a problem.  Some examples include cleaning up piles of leaves, wood, or other cellulose debris around the foundation of the home.  Palm trees should be trimmed regularly and skinned.  Any trees touching the structure should be cut back.  Exclusion is also very important.  Cracks, crevices, gaps, and voids must be sealed off with caulking and fine screening.  Doors need to be tight fitting and vents screened.  The final step is food source reduction, minimizing the amount of general pest insects around the property that scorpions prey on.  When these steps are taken, scorpions are less likely to infest a home or business.
