In the battle against agricultural pests, nature often provides solutions more effective than human-made chemicals.
Recent research by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Prince of Songkla University in Thailand has revealed the remarkable role of Wrinkle-lipped free-tailed bats (Mops plicatus) in controlling insect populations, particularly planthoppers, which are notorious pests in rice farming.
Their ability to hunt at impressive altitudes of up to 1,600 meters gives them a unique advantage over chemical insecticides, which are ineffective at such heights. This discovery has significant implications not just for Thailand but also for Nigeria, where rice farming is a critical industry under siege by destructive pests.
Nigeria’s Rice Farming Challenges: A Similar Battle
Rice is a staple food for more than half of the world’s population, and both Southeast Asia and Africa rely heavily on its production.
Nigeria, as one of Africa’s largest rice producers, faces major setbacks due to insect pests such as planthoppers, which devastate crops and contribute to economic losses for farmers.
Conventional pest control methods, including insecticides, often fail to protect rice fields effectively, especially against airborne pests that move at high altitudes.
The findings from Thailand’s bat study suggest that leveraging natural predators like bats could be a game-changer for Nigerian agriculture.
Bats: The Silent Protectors of Rice Fields
The study in Thailand found that Wrinkle-lipped free-tailed bats are extraordinary hunters with vast foraging ranges. These small but mighty creatures, weighing just 18 grams, travel up to 200 km in a single night and spend over 50% of their time at altitudes exceeding 150 meters.
Their hunting range of 1,743 km² is astonishing—about twice the size of Lagos State. By targeting high-flying planthoppers, they serve as natural pest controllers, reducing the need for chemical pesticides that often harm the environment and human health.
Could Nigerian Bats Play a Similar Role?
Nigeria is home to various bat species, some of which may have the potential to provide similar ecological benefits. However, bat populations are increasingly threatened by habitat destruction, deforestation, and hunting.
Unlike Thailand, where bat caves are recognized for their ecological importance, Nigerian bats often face negative perceptions, being associated with superstition rather than their vital role in pest control.
The Urgent Need for Bat Conservation in Nigeria
If Nigeria wants to harness the power of bats for sustainable agriculture, conservation efforts must be prioritized. Protecting natural bat habitats, such as caves and forests, can enhance their populations and, in turn, support pest control efforts.
Government policies should promote research into local bat species’ dietary habits and flight behaviors to determine their potential role in pest management.
Moreover, awareness campaigns are needed to educate farmers and communities on the benefits of bats in controlling agricultural pests. Just as Thailand has emphasized protecting Wrinkle-lipped free-tailed bats for their ecosystem services, Nigeria could take proactive steps to ensure its own bat populations thrive.

A Sustainable Solution for Nigeria’s Food Security
The findings from Thailand demonstrate that nature often provides solutions where human interventions fail. By learning from this study, Nigeria has an opportunity to integrate bat conservation into its agricultural policies, reducing reliance on chemical pesticides and improving rice yields. Protecting bats is not just an environmental issue—it is a matter of food security, economic stability, and sustainable farming.
If Nigeria can take lessons from Thailand and explore the role of bats in pest control, it could pave the way for a more resilient and productive agricultural sector. The time to act is now—before it’s too late for both Nigeria’s bats and its farmers.
