Suspend Polyzone also has an added polymer that protects the active ingredient from weather, irrigation and mechanical abrasion. The residual for Tempo SC Ultra is approximately 30 days outdoors, while the residual for Suspend Polyzone outdoors is approximately 90 days. They are both general insecticides that are labeled for most of the same pests.
