Scorpions eat crickets, roaches and silverfish. We have a lot of these insects around our home because of all of the extra water supply we have for our plants. A lot of times we find crickets in the walls of our home. That's what draws the scorpions into the house to hunt for their food there. Once the scorpion gets inside the wall of the house, all they need is a sixteenth of an inch, that's the width of a credit card, to squeeze in and now they are inside the home and become a problem inside the house.
