that will require defrosting each year.

cottages or Emergence Cottages. These can be temporarily
stored in the fridge, until weather conditions are reasonable.
|Store cocoons inside Petri dishes that may contain parasitic wasps.
Place on kitchen counter in spring. If any bees emerge
they can be released. Parasitic wasps can be destroyed by freezing .
