More than ten hornets circling her head, some crawling through her hair
In the quiet rhythm of a Singapore afternoon, nature asserted itself with sudden violence near Redhill Market, where a hornet nest hidden in a footpath tree sent four people to hospital on July 10. The incident is a reminder that urban life, however ordered, remains in constant negotiation with the natural world — and that the smallest creatures can carry consequences far larger than their size. Authorities responded swiftly, but the episode raises enduring questions about how cities coexist with the ecosystems woven into their greenery.
- A hornet swarm erupted without warning along Redhill Lane around 1pm, turning an ordinary afternoon into a scene of panic and injury for at least four people.
- An elderly woman bore the worst of it — more than ten hornets circling her head, her ears swollen and bleeding, her senses clouded by headache and dizziness as she sheltered in a nearby toilet.
- Hornet venom is no ordinary sting: it delivers histamine, melittin, and cell-destroying proteins in doses larger than a bee's, capable of triggering anaphylaxis, organ failure, and airway collapse in severe cases.
- The Singapore Civil Defence Force and Tanjong Pagar Town Council moved quickly — cordoning off the area, deploying pest control, and declaring the footpath safe within hours.
- Authorities are now urging residents to stay calm near nests, seek shelter immediately, and call 995 without hesitation if symptoms escalate — speed, they stress, is the difference that matters.
On the afternoon of July 10, a hornet nest tucked into a tree along Redhill Lane became the source of sudden chaos, sending four people to Singapore General Hospital after a swarm descended on passersby near Redhill Market and a Shell petrol station.
Witnesses captured the disorder in vivid detail. A man drinking coffee at the market heard a shouted warning just before an elderly man was chased and stung. Nearby, a woman in her 70s was found sheltering in a toilet, her ears red, swollen, and bleeding, her hair still carrying the marks of the assault. She told a witness she felt dizzy and had a pounding headache. More than ten hornets had swarmed her head during the attack, some crawling through her hair before scattering across the floor.
What makes such encounters especially dangerous is the venom itself. Hornets deliver more of it per sting than bees, and the cocktail — histamine, melittin, phospholipase, hyaluronidase — can trigger severe allergic reactions, cell damage, and in the worst cases, a collapse of blood pressure and airway swelling that proves fatal.
Authorities responded within hours. The Civil Defence Force and Tanjong Pagar Town Council cordoned off the area and activated a pest control contractor to remove the nest. The footpath was declared safe by the time the operation ended.
The town council has since reminded residents to stay calm if they encounter a nest, move away without disturbing it, and call 995 immediately if symptoms become severe. It is not Singapore's first such episode — a 2024 attack at Sungei Buloh hospitalised five — and it is unlikely to be the last, as long as trees and people continue to share the same urban space.
On the afternoon of July 10, four people found themselves in Singapore General Hospital after a swarm of hornets descended on them near Redhill Market. The attack happened around 1pm on Redhill Lane, in the space between Block 78 and a Shell petrol station, where a nest had been built into a tree overlooking the footpath.
Witnesses described a scene of sudden chaos. A man named Chen, who was drinking coffee at the market, heard someone shout a warning about hornets in the tree just before an elderly man was chased and attacked. The incident unfolded quickly enough that another witness, Mei Zhen, found a woman in her 70s in a nearby toilet moments later, visibly distressed and injured. The woman's ears were swollen and bleeding, her hair matted with the aftermath of the attack. She told Mei Zhen she had a headache and felt dizzy. According to Mei Zhen's account, more than ten hornets had circled the woman's head during the assault, some crawling through her hair while others scattered across the floor and door.
The Singapore Civil Defence Force and Tanjong Pagar Town Council responded within hours of the alert. Officers immediately cordoned off the affected area to prevent further encounters. A pest control contractor was activated to remove the nest from the tree, and by the time the operation concluded, the footpath had been secured and declared safe for public use again.
What makes hornet attacks particularly dangerous is the nature of the venom itself. Unlike bees or smaller wasps, hornets deliver a larger payload of venom with each sting. That venom contains histamine, which triggers allergic reactions in the body, and melittin, a compound that causes intense pain. The mixture also includes proteins like phospholipase and hyaluronidase—substances that can damage human cells directly. In the worst cases, victims experience a cascade of serious symptoms: blood pressure drops, vital organs receive insufficient blood flow, and the airway can swell shut, leading to suffocation.
The town council has issued guidance for residents who encounter hornets or discover a nest. The advice is straightforward: stay calm, move away immediately, and seek shelter in a nearby building. Do not attempt to disturb or remove the nest yourself. If stung, leave the area at once. Call 995 for an ambulance if symptoms become severe or if medical help is needed urgently. The distinction matters—not all stings require hospitalization, but the ones that do demand speed.
This was not Singapore's first encounter with this threat. In 2024, a hornet attack at Sungei Buloh sent five people to the hospital. The incidents suggest that as urban areas expand and trees remain part of the landscape, the possibility of nesting insects in public spaces remains a recurring concern. The question now is whether residents will heed the warnings, and whether authorities will continue to monitor known nesting sites before they become dangerous.

The Hearth Conversation Another angle on the story
What made this particular attack so severe compared to other insect stings people might experience?
The sheer number of hornets involved—more than ten attacking the same person—meant multiple stings in rapid succession. Each hornet injects more venom than a bee would, and the chemistry of that venom is designed to cause maximum damage. Histamine and melittin work together to trigger pain and allergic response simultaneously.
Why was an elderly woman specifically targeted, or was it just chance?
The witnesses didn't describe any targeting. It seems more like she was in the wrong place when the nest was disturbed. The elderly man was chased first. Once hornets are provoked, they attack whatever is nearest. Age might have made her less able to escape quickly, which prolonged the exposure.
How quickly did authorities respond?
They were alerted around 1pm and had cordoned off the area and arranged for nest removal the same afternoon. The response was fast enough that no one else was attacked after the initial incident.
Is there a way residents could have known the nest was there before the attack?
Not necessarily. The nest was on a tree on the footpath—visible to someone looking up, but not something most people walking past would notice. That's why the town council's advice focuses on what to do if you encounter one, not how to spot them in advance.
What happens if someone ignores the advice and tries to remove a nest themselves?
They're likely to provoke the entire colony. Hornets defend their nest aggressively. A single person with no protective equipment would be overwhelmed almost immediately, and the injuries could be far worse than what happened here.
