Lawrence from Clearwater, Florida writes
Once sprayed on the surface, how long does it usually last for killing power? If rained on does it continue to kill or do you need to re-spray each time? Is it only a contact killer?
Suspend SC has a residual of 90 days indoors & 30 days outdoors. The product states to spray it when rain is not expected for 24 hours, the product will remain active even if it rains. If you have constant rain, you may need to reapply in 3 weeks rather than 4. It is also not a contact kill, it is a residual kill. A contact kill such as ExciteR Insecticide can be mixed with it.
