Key Features in a Reliable Queen Shipping Cage

A good queen cage isn’t just a box; it’s a carefully designed micro-environment. The most important feature is adequate ventilation. Bees generate heat and moisture, and without enough airflow, they can quickly overheat or suffocate, especially when packed for shipping. However, too much ventilation can dry out the candy plug, making it rock-hard and inedible.

Look for a cage with a dedicated candy compartment that is both easy to fill and holds enough food for several days. The size of the cage also matters. It needs to be large enough for the queen and a half-dozen attendant bees to move around without being cramped, which reduces stress and improves survival rates.

Finally, consider the material and security. Plastic cages are lightweight and easy to clean, while traditional wood cages are breathable. Whatever you choose, ensure the cap or closure is secure. The last thing you want is a queen escaping in a post office sorting room.

The JZ-BZ Plastic Cage: A Modern Standard

If there’s one cage you’ll find in almost every queen breeder’s toolkit, it’s the JZ-BZ. This simple, durable plastic cage has become the industry go-to for a reason. It’s inexpensive, reusable, and brilliantly designed for both shipping and introduction.

The JZ-BZ features a long, tube-like design with a secure cap on one end and a dedicated candy chamber on the other. The ventilation slots are plentiful but small enough to prevent bees from getting stuck. One of its best features is the built-in tab, which allows you to hang the cage between frames in the hive without needing a thumbtack or wire.

Its design also doubles as an introduction cage. The end cap has a small break-away tab that, when removed, creates a second, smaller exit hole through the candy. This gives the colony two points of access to chew through the candy plug, which can speed up a slow release or provide a backup if one side gets blocked. It’s a versatile, no-fuss workhorse.

California Mini Cage: For Mating and Banking

The California Mini Cage is a compact, square plastic cage that serves a more specialized purpose. While it can be used for short-distance shipping, its real strength lies in banking queens and use within mating nucs. "Banking" is the practice of holding multiple caged queens in a single, strong, queenless colony for a period of time.

Because of their smaller size, you can fit many California Mini Cages into a single hive frame designed to hold them. This is incredibly efficient for breeders who need to hold queens for a few days or weeks before they are sold or introduced to new colonies. The cage has a simple friction-fit cap and a small candy chamber, sufficient for short-term holding.

The tradeoff for its compact size is a smaller internal volume and less candy capacity. This makes it less ideal for long-distance shipping where delays are possible. Think of it as the perfect tool for high-density, short-term queen storage within your own operation.

The Classic Three-Hole Wood Shipping Cage

Before plastic cages dominated the market, the three-hole wood cage was the undisputed king. Made from a solid block of wood with three drilled chambers connected by small passages, this cage is a traditionalist’s favorite. The wood is naturally breathable, helping to regulate humidity inside the cage.

The design is simple and effective. One end chamber is filled with candy, the middle chamber is for the queen and attendants, and the third chamber is left empty to provide clustering space. A screen is stapled over the top to provide ventilation and containment. Many old-timers swear that bees are calmer in wood cages and accept queens from them more readily, possibly because the bees can chew on the wood fibers.

However, these cages have downsides. They are heavier and bulkier than plastic, which increases shipping costs. They are also more expensive to produce and are generally considered single-use, as they are difficult to clean and sterilize effectively. It’s a reliable, classic option that still has a place, but modern plastics often offer more convenience.

Nicot Queen Cages: The French Connection

The Nicot system, developed in France, is a comprehensive set of interlocking plastic components for queen rearing, and their queen cages are a key part of it. These cages are known for their high-quality plastic and thoughtful, integrated design. They often feature multiple tabs, slots, and connection points that allow them to interface with other Nicot equipment, like cell cup holders and introduction frames.

Nicot cages come in various styles, but most share common traits: excellent ventilation, a secure closure, and a design that protects the queen well. Some models have a sliding gate that allows you to release the queen directly onto a frame without ever having to handle her. This is a huge benefit for reducing stress on the queen and the beekeeper.

Choosing a Nicot cage often means buying into the broader Nicot system. While they work perfectly well as standalone shipping and introduction cages, their true potential is unlocked when used with a compatible queen-rearing setup. They represent a systematic, rather than a piecemeal, approach to raising queens.

Lyson Polystyrene Cages for Better Insulation

Shipping bees during the shoulder seasons or to extreme climates presents a unique challenge: temperature shock. A standard plastic or wood cage offers little protection from a hot delivery truck or a cold cargo hold. This is where Lyson’s polystyrene cages shine.

Made from a dense, food-grade polystyrene, these cages provide a significant layer of insulation. This buffer helps protect the queen and her attendants from rapid temperature swings, dramatically increasing their chances of arriving alive and healthy. The material is lightweight, so it doesn’t add much to shipping costs, but it offers a level of thermal protection that other materials can’t match.

This is a specialized tool for a specific problem. For most local or temperate-climate shipping, it’s probably overkill. But if you are shipping valuable breeder queens long distances or need to move bees when the weather is less than ideal, the insulating properties of a polystyrene cage can be the difference between a live queen and a dead one.

Roller Cages: Versatility for Queen Rearing

While not technically a shipping cage, no discussion of queen cages is complete without mentioning roller cages. These simple, cylindrical plastic cages with mesh sides are indispensable during the queen-rearing process itself. Their primary job is to protect emerging queen cells.

You place a nearly mature queen cell inside a roller cage just before she is due to emerge. This protects the cell from being torn down by the colony and prevents the newly emerged virgin queen from being killed by other virgins. It allows you to hatch multiple queens in a single incubator or cell-finishing colony without chaos.

Roller cages are also used to hold virgin queens for a day or two before introducing them to mating nucs. The open mesh design allows the colony’s scent to permeate the cage, beginning the introduction process. They are the essential link between the queen cell and the shipping cage.

Preparing Cages with Candy for Safe Transit

The best cage in the world is useless without the right food source. The "candy" plug in a queen cage serves two purposes: it provides food and water for the journey, and it acts as a slow-release mechanism for introduction. Getting the candy consistency right is a craft in itself.

Queen candy is essentially a stiff fondant, made from powdered sugar and either corn syrup or inverted sugar syrup. It must be firm enough not to run or liquefy in the heat, which could drown the bees. But it must also be soft enough for the bees to consume it and eventually chew through it to release the queen.

To prepare a cage, you firmly press the candy into its dedicated compartment, ensuring there are no air bubbles. For a three-hole wood cage, you’ll plug one of the end holes. For plastic cages like the JZ-BZ, you fill the designated chamber. Always add a single drop of water to the candy just before adding the bees; this provides immediate hydration and helps keep the candy from drying out too quickly.

Ultimately, the cage you choose depends on the task at hand. The JZ-BZ is a fantastic all-rounder, the California Mini excels at banking, and polystyrene offers critical protection for tough shipments. Don’t view the cage as an afterthought. It’s the final piece of the puzzle in a successful queen-rearing operation, ensuring your hard work pays off with a healthy, productive queen in a new hive.
