I make a bug and spider repellent that my aunt taught me. Buy a small bottle of peppermint oil, and one of basil oil.pour into a sprayer bottle with a quick squirt of dishsoap. Fill the bottle with cool water. Shake before each use. I spray around my doors and windows each time they are opened and along the base of the house outside and along the top and bttom of all my walls once a year. I have not seen a big or spider in years. I hate bugs. I want them all dead, yes, I know that is impossible and they do preform a service for us, but they get the whole world, as long as they stay away from me!
