CHIANG RAI — A traditional Thai New Year ceremony turned into a scene of chaos Thursday morning when a massive swarm of giant honeybees attacked dozens of guests at the Chiang Rai Governor’s official residence. The incident, which occurred around 9:15 a.m. on April 23, 2026, sent at least 30 people to the hospital after smoke from food stalls reportedly agitated a large nest in a nearby tree.
Government officials and private sector representatives had gathered at the century-old residence on Thanalai Road to participate in the “Dam Hua” ceremony. This northern Thai tradition involves pouring scented water on the hands of elders—in this case, Governor Chucheep Pongchai—to show respect and seek blessings for the Songkran season.
The festivities were in full swing when the colony of giant honeybees (Apis dorsata), nesting high in a large tree near the provincial Red Cross office, suddenly descended upon the crowd. Witness reports describe a sudden cloud of bees diving toward guests, causing many to flee the grounds in a panic.
Dozens Injured in Sudden Swarm
According to the Manager Online, the attack left many attendees nursing multiple stings. Some victims were seen frantically removing their shirts to shake off clinging bees, while others attempted to help those trapped in the thick of the swarm.
“The bees just started diving at everyone,” said one witness who fled toward the street. “People were screaming and running in every direction. It happened so fast.”
Chiang Rai provincial authorities quickly coordinated with emergency services as the scale of the injuries became clear.
- Emergency Response: Several ambulances were dispatched to the residence to provide immediate first aid.
- Hospitalizations: Between 10 and 30 people were transported to Chiang Rai Prachanukroh Hospital for urgent treatment.
- Condition of Victims: Most suffered from localized swelling and allergic reactions, though no fatalities have been reported.

Initial investigations by local officials suggest that the swarm was triggered by the very hospitality meant to welcome the guests. Several food booths had been set up on the lawn to serve those attending the ceremony.
Investigators believe that smoke from charcoal grills used for barbecue stalls drifted upward into the canopy. The smoke likely irritated the giant honeybees, which are known to be highly territorial and sensitive to environmental disturbances. The colony responded by defending the nest, targeting the crowd below.
Ceremony Proceeds After Tense Standoff
Despite the initial terror, the bees eventually retreated to their nest or dispersed as the smoke cleared. Once the area was deemed safe and the injured were under medical care, Governor Chucheep Pongchai proceeded with the formal “Dam Hua” ritual.
Officials noted that while the event was marred by the attack, the importance of maintaining the Lanna cultural tradition prevailed. However, the incident serves as a stark reminder of the risks of hosting large outdoor gatherings near active wildlife habitats, especially during the hot season when bees can be more aggressive.
The Governor’s office has not yet commented on whether the nest will be relocated or if safety protocols for future outdoor events will be adjusted.
