under porch and in garage
Sevin granules is not labeled for cockroaches and the product cannot be used indoors in a garage because it has to be watered into be activated. Cyper WP would be a better choice for you. This product is a powder that you mix with water and then apply using a handpump sprayer. Cyper WP can be used under and on your porch and in and around your garage to control roaches.
