CELL BUILDER REBUILD

Full Cloake Board method  ·  Frosty Meadow  ·  Round 2 — Spring 2026

⚠️ Critical: Wild Cell Destruction

⚠️ This is the most important step. Do not skip or rush it.

Every single frame that goes into the cell builder must be shaken completely free of bees and inspected by two people independently before being returned to the hive. You are looking for any queen cup or queen cell — even empty ones get destroyed. Do not waste time checking whether there are eggs inside a cup. If it looks like a queen cell or cup, destroy it. No exceptions.

Experience shows nine capped wild cells on a single frame alone during a routine weekly check. If even one of these hatches, that virgin queen will immediately find and destroy every grafted queen cell you have carefully raised — ending your entire batch instantly. All your work, all the bees' work, gone in minutes.

The two-person inspection protocol:

Step-by-Step Timeline

1

✓ Wednesday — Newspaper combine

Bring in two strong colonies & newspaper combine

Bring two very strong colonies from other yards. Set one with entrance facing front, one with entrance facing back. Remove the weaker queen and unite the two brood chambers using newspaper. Within about a week the colonies are fully merged and ready to configure as the cell builder.

2

✓ Day before graft — Complete

Configure the stack & sequester the queen

Build the full hive stack with all four queen excluders and the Cloake Board in closed position. Locate and confine the queen to the lower deep box. Shake 15 frames of bees up into the upper deep cell builder box.

Upper deep box frame contents (in order):

  • 1-gallon internal feeder
  • Frame of pollen (or pollen patty on top of upper QE)
  • New graft frame — placed in centre to be polished for 24 hours
  • Frame with a small amount of open brood — station right next to graft frame to attract nurse bees
  • Frame of foundation — place next to graft frame on other side to discourage excess comb
  • Remaining frames: capped brood with emerging bees (no young larvae — young larvae compete with grafts for food)

Lower medium boxes: 6 frames brood, 1 frame resources, 3 frames foundation or drawn comb. Queen roams freely through the lower deep.

⚠ Critical — Every frame, two people

Wild cell inspection & destruction — every frame, no exceptions

Before any frame goes back into the hive, shake every bee off it completely. Person 1 checks and destroys all cups and cells. Person 2 double-checks independently. Tip each frame to look up into the cells from below — much easier to spot cups this way. Sort frames as you go: brood frames to one pile, honey/food frames to another. This makes reassembly faster and more organised.

▶ Thursday — Cell builder prep day

Entrance management & final setup

Entrance configuration (Cloake Board method): Tape shut any extra entrance holes on both medium brood boxes. Use the natural entrances of the two original colony positions — one entrance facing front, one facing back. Put a reducer on the back entrance. This creates the crowded, congested feeling inside the hive that drives swarm impulse and motivates the bees to raise excellent queens.

Confirm Cloake Board is in the closed position. Fill feeder with sugar syrup. Add pollen patty if not using a pollen frame. The upper deep is now queenless and packed with young bees — ready to accept the graft tomorrow.

4

▶ Friday — Graft day

Graft the larvae & introduce the frame

  • Remove feeder and top queen excluder
  • Remove the graft frame that has been polishing for 24 hours
  • Graft young larvae (under 24 hours old) into the polished wax cups
  • Return the grafted frame to its central position in the upper deep within one hour of grafting
  • Replace queen excluder on top, replace feeder, close up the hive

The queenless, bee-packed upper box will immediately begin drawing those cells using both swarm impulse and emergency supersedure impulse — they can't smell a queen through the closed Cloake Board.

5

Sunday — Two days after graft

Pull the Cloake Board slide to halfway open

Pull the metal slide out to the halfway position. This allows the bees to begin normalising within the colony and they continue raising the queens — but now driven only by swarm impulse rather than the emergency supersedure impulse. finds this transition produces consistently better results. The cells remain protected and undisturbed. Do not open the upper box.

6

Upcoming — Following Wednesday

Repeat weekly — prep for next batch

Distribute mature cells from current batch into mating nucs. Then immediately repeat the full setup cycle: wild cell inspection on all frames, reconfigure upper box, insert new graft frame to polish, prep entrances, fill feeder. This weekly rhythm is what allows the cell builder to run continuously all season — Research operations using this method runs 2-3 cell builders simultaneously producing 100-150 cells per week.

Weekly Schedule ( Method)

DayTaskCritical Notes
Wednesday Newspaper combine — bring in two strong colonies, remove weaker queen, unite brood chambers with newspaper One entrance facing front, one facing back. Reducer on back. Allow ~1 week to fully merge before cell builder setup.
Thursday Cell builder prep — wild cell check on every frame, configure stack, insert graft frame to polish, manage entrances, fill feeder Two-person wild cell inspection on every single frame. Non-negotiable. Cloake Board in closed position.
Friday Graft day — remove polish frame, graft larvae, reintroduce within 1 hour, close up Larvae must be under 24 hours old. Return grafted frame within 1 hour maximum.
Sunday Pull slide — move Cloake Board slide to halfway open position Two days after graft. Do not open the upper box. Slide only.

Before You Start — Checklist

☐ Grafting bar & wax cups

Fit with wax cups, polished and ready. Insert into cell builder box today to be polished by bees for 24 hours before graft day.

☐ Queen excluders × 4

All four accounted for. Wood-rimmed preferred — metal edges can bend and create gaps that queens slip through.

☐ Cloake Board

Vaseline the grooves at start of season so the slide moves freely and doesn't get propolised shut.

☐ Entrances configured

Tape all extra entrance holes on medium boxes. Reducer on back entrance. Front entrance open. Two entrances total — creates crowded, congested feeling that drives swarm impulse.

☐ Supplies

Pollen patties  ·  Sugar syrup  ·  Clean 1-gallon internal feeder (occupies one frame slot in the upper deep)

☐ Two people for wild cell check

Do not attempt the wild cell inspection alone. You need Person 1 to inspect and Person 2 to independently double-check every single frame.

Hive Stack Diagram — Full Configuration

Four queen excluders total. Queen is confined to the lower deep — the queen roams freely through both. She cannot move up past QE2 or down past QE1. She cannot move up or down beyond the flanking excluders. The upper deep is fully queenless. Virgin queens from outside cannot enter the upper deep through the top excluder.

📝 Notes for This Run — Round 2

Box configuration: Back to the classic single 10-frame deep on the bottom for the queen zone — same configuration used in the first run of cells.

Queen excluder count: Using 4 QEs — same count as the first run. The QE above the upper deep prevents virgin queens flying in from outside and destroying your cells.

Wild cell protocol: Two-person inspection is now a formal step in the process, not an afterthought. Experienced cell builders using this method found 9 capped wild cells on a single frame. This is your biggest single risk.

Entrance management: Tape all extra entrance holes. Reducer on back entrance only. Front entrance open. Two entrances, crowded feeling, drives swarm impulse.

Feeder: 1-gallon internal feeder now shown in the upper deep diagram. Amount of syrup added depends on current nectar flow — less during a strong flow, more when flow is poor.
