Crocodiles and snakes on patrol? BSF considers natural barriers along Indo‑Bangla border

The Border Security Force (BSF) is actively studying an unconventional proposal to use snakes and crocodiles as natural deterrents in unfenced riverine and marshy gaps along the 4,096‑km India‑Bangladesh border , where traditional fencing is difficult or impractical, officials said on Monday. The exercise remains at the feasibility and discussion stage and no official implementation order has been issued yet.

The idea, reportedly prompted by directions from Union Home Minister Amit Shah , was the subject of a meeting at the BSF headquarters in Delhi on February 9. Subsequently, units along the eastern and northeastern sectors were asked to examine whether reptiles like snakes and crocodiles could act as a “natural security shield” in vulnerable riverine gaps where physical barriers cannot be erected .

Officials noted that around 175 km of the India‑Bangladesh boundary consists of rivers, marshes and swampy terrain , zones where conventional fencing and barriers are often impossible to maintain , leaving them susceptible to infiltration, smuggling and cross‑border crime .

However, field commanders and local considerations have raised significant concerns about the practicality of the plan. Many inhabited villages lie close to these water bodies, and the presence of potentially dangerous reptiles could pose risks to civilians , especially during flood seasons when animals and people may both be displaced.

The BSF has emphasised that the current initiative is strictly about evaluating feasibility, effectiveness and safety from an operational perspective, not about immediate release of animals. The evaluation includes identifying suitable river stretches and analysing whether reptiles could realistically deter illegal crossings without imposing undue harm on local populations or the environment .

Alongside this idea, the BSF is continuing to strengthen border monitoring with technology‑driven solutions such as drones, sensors, thermal cameras, GPS tracking and night‑vision equipment , and by enhancing mobile connectivity at remote posts . These tools are part of a broader strategy to secure unfenced and dark zones of the frontier.
