Visual Guide for Beekeepers: Interpreting Swarm Trap Bee Activity
Problem: Beekeepers, especially those who are newer to the craft, often struggle to tell the difference between scout bee activity at a swarm trap and a fully established, moved-in swarm. Questions like "Did they move in?" and discussions about interpreting bee numbers, flight patterns, and the presence of pollen versus propolis can lead to anxiety, premature disturbance of potential swarms, or missed opportunities for timely capture.
Product Suggestion: "Swarm Trap Occupancy Indicator Card: Scouts or Settled?"
This would be a durable, laminated, weatherproof visual guide designed for quick field reference. The card would feature:
- Clear, Comparative Visuals: High-quality photos or detailed illustrations contrasting:
- Scout Bee Signs: Small numbers of bees (e.g., 5-30), bees flying around the trap entrance, entering and exiting, but without a constant, heavy stream. Explicitly states "No pollen being carried in."
- Moved-In Swarm Signs: A large, continuous stream or "cloud" of bees actively flying to and from the entrance. Bees fanning at the entrance. Critically, clear images of bees carrying pollen on their hind legs.
- Key Differentiators Checklist:
- Activity Level: Low/intermittent (Scouts) vs. High/constant (Swarm).
- Pollen: "Are bees carrying pollen into the trap (bright pellets on legs)?" (Yes = Strong Swarm Indicator).
- Propolis vs. Pollen Debris: Visual distinction between sticky propolis smears (not a primary moving-in sign) and dropped pollen pellets.
- Numbers: Approximate bee counts for each scenario.
- Actionable Advice:
- If Scouts: "Patience is key. Avoid disturbance. Continue to monitor for increased activity and pollen."
- If Swarm (pollen confirmed): "Swarm likely established! Plan to secure and relocate your new colony, typically in the cooler evening hours."
- Common Pitfalls Section: Briefly notes issues like mistaking robber bees for swarm activity or disturbing the trap too soon.
Expected Benefit: This guide would help beekeepers to:
- Reduce Uncertainty: Make more confident assessments of swarm trap activity.
- Improve Capture Rates: By avoiding premature disturbance of scout bees or newly arrived swarms, and by enabling timely securing of confirmed swarms.
- Minimize Beekeeper Anxiety: Providing clear, visual, and actionable information alleviates stress associated with misinterpretation.
- Educate: Reinforces key beekeeping knowledge about swarm behavior and signs like pollen as an indicator of brood rearing.
- Save Time & Effort: Prevents unnecessary actions based on misjudgment, such as prematurely moving or dismantling a trap.

Did they move in?

Just checked a swarm trap I haven’t seen in over week and saw this….
This is in the PNW and a local here told me this is the peak time god swarms here.
It was baited with a couple empty fra

I would also expect a bit more activity but is that pollen or propolis on the bottom of the entrance?

If you see pollen...

Looks like scouts to me… but I can’t say for certain. When the swarm moves in, there will be a constant to’ing amd fro’ing. Leave it alone I till you see pollen in the morning.

They don't spread pollen around like that, only propolis. When pollen falls off their legs it is in little clumps and wouldn't leave a mark like that.

Don’t be like me. I got excited and it was just scouts and robbers. Had to lift the box back onto its 8ft tree.
Wait for pollen. Pollen means brood.
