Most criticized the responsible agencies, especially the Chiang Mai Municipality, for failing to control pests and street trash in a key tourism zone. Many warned that the scene hurts the city’s image at a time when Chiang Mai is being promoted as a world-class destination. Rats and cockroaches, seemingly on a routine schedule, arrive in numbers, chew through the bags and swarm the food waste. Residents say a clean, predictable system for food waste would cut infestations and improve street hygiene within weeks. They want Chiang Mai to adopt similar steps, then communicate them clearly to businesses and the public.
