Quick Summary

The town of Bowden in Alberta recently announced the discovery of a dead rat, prompting calls for action from the provincial "rat patrol." This comes as cities around the world see significant increases in rat populations due to rising global temperatures; Washington DC saw a 390% increase over ten years. Despite these challenges, Alberta has maintained its rat-free status since 1950 through rigorous measures including a dedicated “rat control zone” and aggressive legislation requiring residents to eliminate any rats they find.

Story summary

In Alberta, Canada, a province historically free of rats since 1950 due to its Rat Control Program, officials recently faced a significant challenge when a dead rat was found in the town of Bowden. The discovery prompted local authorities to call on the provincial "rat patrol" for investigation and urged residents to report any signs or sightings of rats. Although no specific location within Bowden was provided, this incident marks a notable breach in Alberta's long-standing reputation as a fortress against rodent infestation.

Globally, rising temperatures have contributed to an increase in rat populations in major cities; researchers reported a 390% rise in Washington DC and up to 162% growth in New York over the past decade. In Toronto, Canada’s largest city, officials are grappling with what they term a "perfect rat storm," witnessing a surge of 186% in rats during the same period.

Alberta's proactive measures since the 1950s have involved establishing a "rat control zone" stretching from Cold Lake to the Montana border, aiming to prevent any incursions. Despite this extensive effort, the recent discovery highlights the increasing vulnerability of even isolated regions to urban pests as environmental conditions change globally.

🔮 In the 1950s, suspecting rats might try to enter from the east by way of neighbouring Saskatchewan, Alberta officials created a “rat control zone” – a strip of land measuring 373 miles by 18 miles (600km by 30km) – to monitor incursions that ranges from Cold Lake in the north to the Montana border in the south.

Narrative

Unlike other regions in the world that have been overrun by the wily and adaptable urban mammals, Alberta has actively fought rats from entering at all. “Albertans have enjoyed living without the menace of rats since 1950 when the Rat Control Program was established,” the province says in its rat guide.
