One of the best ways to keep scorpions out of your home is to make it difficult for them to get in. This means using a silicone caulk on all of the cracks where they might be able to enter. Being thorough is the key, since they can easily enter through even the tiniest of spaces. Be sure to caulk around window frames and around all of the crack in the foundation. Look for gaps in your baseboards and around window frames. The better job you do on sealing your home, the more of a problem it will be for the scorpions to enter.
