Evaluate the existing queen's performance

Before deciding whether to let supercedure proceed or intervene, assess the current queen's condition. A thorough evaluation tells you whether the colony's instinct to replace her is justified or premature.

What to Check

• Brood pattern: A healthy queen produces a compact, wall-to-wall pattern with fewer than 10% empty cells per frame. A scattered "shotgun" pattern with many gaps signals declining fertility or poor mating.
• Queen appearance: Look for physical damage (torn wings, missing legs), a shrunken abdomen, or darkened/bald patches on the thorax. Bald, dark queens are typically 2+ years old.
• Colony temperament: Increased defensiveness or nervous running on frames can indicate failing queen pheromones.
• Laying rate: A prime queen lays 1,500-2,000 eggs/day in peak season. Noticeably sparse brood across multiple frames suggests decline.

Tips

• If the queen looks healthy but brood is spotty, suspect poor mating or viral infection rather than age
• Mark unmarked queens during evaluation so you can confirm whether the colony supersedes her later
• A queen under 12 months old with supercedure cells may indicate a genetic or disease issue worth investigating further
