JZ-BZ queen cell protector caps for protecting queen cells during introduction. They help maintain the optimum temperature while securely protecting the queen cell.
Queen Cell Protector Cap No. 2 JZ-BZ USA (with one side lug)
These caps are used in many Western beekeeping operations to protect queen cells when transferring them from a cell-builder colony to new bee colonies, splits or nucleus hives (nucs). Even when placing a queen cell back into its own colony, protective queen cell caps are used. The soft plastic helps prevent the queen cell from being crushed by neighbouring frames or fingers. The large grid-shaped perforation helps avoid damage to the queen cell while maintaining the optimum temperature for the full development of the queen bee.
JZ-BZ caps are made in two types and differ only in their lugs:
- Cap No. 1 with lugs on both sides for installation between frames
- Cap No. 2 with an extended lug on one side for inserting into the comb


The JZ-BZ No. 2 cap can be installed in the middle of the comb by inserting the extended lug into the comb. It is considered that the middle of the comb provides a more suitable temperature for queen cell maturation and queen bee development.
JZ-BZ caps are reusable, and by using them the beekeeper can move away from old, unreliable methods of protecting queen cells with foil or other materials.
