The Quick Strips have a treatment period of just 7 days. Daytime temperatures must be between 50° F – 84° F (10° C- 29° C). Strips are laid across the tops of the brood frames and they can be used during a honey flow if necessary. A spacer rim is no longer needed for these strips, but you still need to wear the recommended safety equipment for acid. This package contains enough strips for one hive. Now available in all states and certified for use in the production of Organic Honey!
