In early 2016, a homeowner in Toowong reported a highly unusual case of stingless native bees (Trigona species) fighting on her balcony. Thousands of bees were found dead over several weeks, raising questions about native bee behaviour and how to respond.
Why Do Native Stingless Bees Fight Each Other?
1. Territorial Conflict Between Colonies
- Native stingless bees like Trigona carbonaria can become aggressively territorial.
- Swarms from rival colonies may fight to the death to defend or claim a foraging zone.
- Fighting usually occurs outside or near a hive—but this case involved fighting with no visible nest nearby.
2. Bees May Mark Territory Using Droppings
- Yellow and brown bee droppings were found along balcony timber.
Bees were observed “marking” the area as if it were a strategic location, possibly mistaking it for a hive site or resource zone.
How Far Do Stingless Bees Travel from the Hive?
| Behaviour | Distance |
| Daily foraging radius | Up to 500 metres |
| Aggressive swarm activity | Typically < 300 metres from hive |
| Nest proximity in this case | Likely within 300m, though hidden |
- No nest was located nearby, but based on bee behaviour, at least two or three hives may have been in the vicinity.
Do Stingless Bees Pose Any Danger?
- Trigona bees are non-stinging and native to Queensland.
- They cannot harm humans, though they may deliver a small bite if provoked.
- Their swarms are not aggressive towards people, even during conflict with other hives.
Why Are Native Bees Important—and Threatened?
1. Compete Poorly with Feral Honey Bees
- Feral honey bees outcompete native bees for resources and nesting hollows.
- This puts pressure on native fauna like possums, gliders, parrots, and kookaburras, which also rely on tree hollows.
2. Life Cycle Still Not Fully Understood
- Researchers and beekeepers continue to study native bee behaviour, particularly swarm conflict and nesting.
- Enthusiasts maintain hives for honey and pollination, supporting urban biodiversity.
What to Do if You Suspect a Native Bee Conflict Near Your Home
- Observe the swarm without disturbing them.
- Do not spray or attempt to relocate the bees yourself.
- Contact a professional to inspect for a hidden nest or territorial triggers.
- If the bees are causing disruption, Peter the Possum Man can provide safe, lawful native bee removal or relocation if viable.
Key Takeaways
- Stingless native bees can engage in prolonged swarm fights due to territorial disputes.
- Such behaviour may occur without a visible hive, making it hard to trace the source.
- These bees are harmless to humans but vital to local ecosystems.
- If bee swarms become a persistent issue, professional assessment is recommended.
