Viral Video Exposes Chiang Mai’s Dirty Secret
Chiang Mai’s image takes a massive hit after a stomach-churning video goes viral. The clip, filmed late at night along Moon Muang Road near the famous Tha Phae Gate, shows huge rats and cockroaches gorging themselves on piles of rubbish.
The footage, posted by a popular local Facebook page, captures dozens of rats—some nearly as big as small cats—tearing into bin bags and fighting over scraps. Cockroaches pour from drains and cracks, joining the midnight feast.
One foreign woman’s scream pierces the night as she flees the scene, unable to hide her horror.
Outrage Erupts Over Shocking Scenes
The video sparks a flood of angry comments. Most blame city officials, especially Chiang Mai’s administration, for failing to control pests and manage street rubbish in a key tourist zone.
“Disgusting and embarrassing,” one local writes. Others warn the scenes could destroy Chiang Mai’s reputation just as it’s being promoted as a world-class destination.
The livestream was filmed on the inner moat side of Moon Muang Road, a bustling strip lined with restaurants, convenience stores and guesthouses. After closing time, businesses leave tied black bin bags on the kerb for early morning collection.

Tourists Caught in Rat-Infested Chaos
As the night deepens, the pavement transforms into a buffet for pests. Rats and cockroaches, almost on schedule, swarm the bags, chewing through plastic and spreading food waste everywhere.
A foreign couple walks straight into the chaos. The man tries to stay calm, but the woman screams and sprints away, dodging the rubbish. Other passers-by film the spectacle, while some recoil in disgust. Several rats dash into traffic and are crushed by cars.
The video spreads like wildfire, bringing fresh embarrassment to a district that welcomes thousands of visitors daily.
Locals Say: “This Happens Every Night”
Residents and business owners insist this is nothing new. “It’s like this almost every night, especially after midnight,” says one shopkeeper. Complaints have dragged on for years, but little changes.
Locals point to Chiang Mai’s recent Travel + Leisure ranking—number one in Asia, number two worldwide, based on over 180,000 readers. They fear scenes like these will stain the city’s name and scare off tourists.

Inspections Reveal Worst Hotspots
On-the-ground checks confirm the pattern. The worst areas are along the moat loop, where eateries cluster and bin bags overflow with food waste. Even tied bags are no match for hungry rats.
By morning, crews clear the mess, but the damage to public trust and hygiene is already done.
Locals Demand Urgent Action
Residents are calling for a coordinated response. Their demands include:
- Shifting rubbish collection to late at night, not early morning, to cut pest feeding time
- Issuing sealed, rodent-proof bins for food waste instead of loose bags
- Stepping up pest control with baits and traps around drains and known nests
- Repairing cracked pavements and sealing drain access to block cockroaches
- Enforcing strict waste rules for restaurants, hotels and shops
- Raising fines for improper disposal and repeat offenders
Health fears are growing too. Rats and cockroaches can spread disease. Open piles of food waste increase the risk of contamination and foul smells, attracting even more pests.
Tourism Workers Fear for Chiang Mai’s Global Reputation
Tourism workers are deeply worried. The moat area, including Tha Phae Gate, is one of Chiang Mai’s most photographed spots. Night markets, bars and guesthouses draw crowds well past midnight. Visitors who witness a pavement swarming with rats are likely to post about it.
In a city famous for charm, street food and walkability, this kind of notoriety hurts. Locals stress the solution is simple.
Other cities have cut rat numbers by changing collection times, using lockable bins and tightening restaurant rules. Chiang Mai, they say, must follow suit—and make sure everyone knows the new rules.
The message from locals is clear: fix rubbish handling, cut off the food supply, and the rats and cockroaches will vanish. Leave rubbish out overnight, and the nightmare returns every single night. For a city celebrated by travellers worldwide, the choice seems obvious.
