Suspend SC is a very popular product for stink bugs and widely used by our customers. The key to stink bug control is to treat in the fall when the stink bugs normally look for entry into a home. Even more important is to make sure there are no cracks around windows or under doors. You should seal all cracks and holes with caulk or other suitable material to prevent entry from stink bugs and other pests during the fall and winter.
Suspend SC should be applied directly into cracks, crevices, wall voids and small spot treatments. When applied as specified on the product label, cleaning your floors would have no effect on the product.
