Some people use lavender to deter pests (including scorpions) and there seems to be some evidence to support this. Planting lavender around your house is a helpful tool to keep scorpions away.
Seal Your Home
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 cracks in the foundation. Look for gaps in your baseboards and around window frames. The better job you do of sealing your home, the more difficult it will be for the scorpions to enter.
Safely Protect Your Pets
Dog owners can provide protection to their pets from mosquitoes and other biting pests with approved repellent products. These products are commercially available from veterinarians, and can protect against mosquito bites, which can transmit WNV and heartworms, and tick bites, which can transmit Lyme Disease. Cat owners should keep their pets indoors during the summer months to avoid exposure to mosquitoes.
Avoiding Mosquito Bites
Take extra care to use repellent and protective clothing during evening and early morning, or consider avoiding outdoor activities during these times. Install or repair window and door screens, so that mosquitoes cannot get in your home. Place mosquito netting over infant carriers when you are outdoors. At least once or twice a week, empty water from flower pots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans, as these can be breeding grounds for mosquito larvae. Get rid of outdoor items that hold water, such as old tires, tin cans, buckets, drums, or bottles. Check for clogged rain gutters and clean them out. Check for containers or trash in places that may be hard to see, such as under bushes or under your home.
