Alpine was sprayed twice but a few roaches survived. I don't think additional spray of Alpine would work. If I want to switch to temprid SC, how long do I need to wait before spraying temprid on the same crack and crevices?
We would recommend waiting 30 days after an application of Alpine WSG before applying a secondary product. For best roach control, we would recommend one of our roach control kits. It contains all the products needed for best control.
