A sudden surge in rat sightings across Taipei has sparked a public health concern and an early political clash as the city prepares for the 2026 mayoral elections. Residents have reported seeing rodents roaming freely in prime districts, with dozens of rats sighted specifically around the Shuanglian Market area, leading to widespread public alarm.
Political Friction Over Pest Control
The infestation has become a flashpoint between incumbent Mayor Chiang Wan-an of the Kuomintang and Legislator Shen Po-yao of the Democratic Progressive Party. As the 2026 election cycle nears, Shen has increased his presence at local events and engaged in several public exchanges with the Mayor.
To address the crisis, Legislator Shen Po-yao suggested reducing the rodent population by interfering with their reproductive hormones. Mayor Chiang Wan-an responded by stating that the city is open to various opinions but will continue to rely on the advice of experts.
The city government’s current strategy involves the utilize of poisoning alongside comprehensive environmental disinfection targeting restaurants, business districts, and various markets.
Urban Renewal Linked to Rodent Surge
Hsu Li-min, the former Director of the Taipei City Social Affairs Bureau, has suggested that the root cause of the infestation is not a lack of budget or cleanliness. Instead, he points to the significant increase in urban renewal projects and the reconstruction of hazardous buildings in the city.
According to Hsu, construction activities disturb existing rodent habitats, forcing rats to flee their nests and emerge into public view. He argued that addressing the problem at the source—before construction begins—is more practical than relying on poisoning or theories regarding food waste covers.
The 2019 Extermination Model
Hsu Li-min highlighted a historical precedent for managing rodent displacement. The 2019 Huannan Market operation followed a strict timeline: baiting and merchant education 120 days prior, path-specific baiting at 90 days, glue boards and corpse removal at 60 days, and cages combined with spraying at 30 days.
The process concluded with the installation of blocking facilities one week before the move and the use of manual netting by cleaning crews on the day of demolition to capture remaining rodents.
Given the current political climate, these differing views on urban management could lead to further public debates over the city’s infrastructure and health policies leading up to the late 2026 elections.
