Poisonous snakes will migrate to cities by 2050 according to WHO

Published on May 26, 2026 | Translated from Spanish

A recent WHO study warns about the displacement of venomous snakes such as black mambas and kraits toward urban areas due to climate change and human expansion. By 2050 and 2090, millions of people in new regions could face a higher risk of bites. Currently, four million cases are recorded annually, concentrated in the tropics and South Asia, but the danger map is being redrawn.

Warning systems and apps to predict encounters with snakes 🐍

Current technology allows the development of predictive models that cross-reference climate data, deforestation, and snake migration patterns. IoT sensors in risk areas and mobile applications with real-time alerts could reduce incidents. Drones for mapping changing habitats and AI systems that identify dangerous species by image are also being researched. These tools aim to anticipate wildlife movements before they reach populated areas.

The forced relocation of snakes: welcome to the neighborhood 😅

It seems snakes also want to try urban life and move to areas with better climate and services, even at the cost of our peace of mind. Soon we might have to share the elevator with a black mamba on the way to work. Of course, at least the rents in the neighborhood will still be just as venomous.
