I intend to spray on the ground just at the intersection of the foundation to prevent spiders from coming in my house
Cyzmic CS would be a great product as a barrier spray to kill insects that contact the treated surface. While there is not a product that will keep them out, sealing up all cracks and crevices that allow them entry is best way to prevent insects inside. We also have a great general pest prevention guide that can help.
