  • Spray all window and door frames along with the outside of your home. Anywhere you think the rain spider would enter, spray it with pesticide and they should stay out.
  • Install a yellow bug light that kills off other insects. Since spiders will go where there tends to be food, they will end up inside your home if they think there are other insects in there to eat. Therefore, by using a bug zapper that will kill off any other insects, you will decrease any reason for a rain spider to enter your home.
  • Surround your home with sevin dust. This needs to be put around the foundation of your home. You want to do it when there hasn’t been rain in two days and you don’t expect any in the next few days. This will keep the dust around your home and prevent any spiders from entering.
