The ICAR-Central Island Agricultural Research Institute (CIARI) has been granted a patent for its innovative invention, a “Fly Repellent Composition and Method of Preparation Thereof.” The patent, issued on September 12, 2025, recognizes a formulation developed by a team of researchers at the Sri Vijaya Puram-based institute, which promises an effective and eco-safe solution to one of the most persistent problems faced by households, markets, and animal rearing spaces.
Flies have long been identified as a significant health hazard for both humans and animals. They serve as carriers of disease-causing organisms, transmitting infections either mechanically or by acting as intermediate hosts of parasites. While the adult stage of flies spreads diseases, the larval stage can cause a condition known as myiasis, commonly referred to as maggot wounds. For decades, efforts to control flies have relied largely on chemical or biological methods, each with its own limitations.
The CIARI invention presents a unique approach by blending chemical and indigenous components in varying permutations to create a ready-to-use spray. The formulation consists of three chemical compounds combined with a non-toxic organic polar solvent and enriched with essential oils. Unlike many existing solutions, the new repellent prioritizes safety for humans, animals, and the surrounding environment while maintaining high efficacy.
According to the institute, the spray effectively repels house flies and flesh flies for up to four hours in open environments such as fish markets and animal sheds. In enclosed spaces like sweet shops, bakeries, and homes, the effect lasts for as long as 24 hours, offering long-term relief from infestations. The ready-to-use format also means that users can apply the spray without additional preparation, making it accessible for both domestic and commercial purposes.
The research team behind the innovation includes Dr. Talaviya Harshangkumar, Dr. Arun Kumar De, Dr. D. Bhattacharya, Dr. P. Perumal, Dr. Abhilash, Dr. T. Sujatha, Dr. Jai Sunder, and Dr. E. B. Chakurkar. Their collective expertise in animal health, entomology, and agricultural sciences played a crucial role in developing a formulation that balances safety, effectiveness, and practicality.
The invention has already been commercialized in collaboration with local entrepreneur Sainath Shenoy of Mahalasa Agro Products, based in South Andaman. This partnership is expected to pave the way for widespread availability of the product across the islands and potentially in other regions of India. By involving a local entrepreneur, the initiative not only promotes innovation but also supports regional enterprise, contributing to the economic fabric of the islands.
The patent award marks another milestone for ICAR-CIARI, which has been engaged in agricultural and allied research catering to the unique needs of the Andaman and Nicobar Islands. Known for innovations in livestock management, crop science, and sustainable practices, the institute has played a key role in addressing local challenges through science and technology. The fly repellent patent adds to its growing list of contributions that extend beyond the islands to national and global contexts.
Experts view the invention as particularly significant for coastal and tropical environments where flies are abundant and pose health risks. By ensuring the use of non-toxic components, the product aligns with global concerns around chemical safety and environmental sustainability. The emphasis on indigenous elements further reflects an effort to integrate traditional knowledge with modern science.
As the patented product enters markets, its impact will be closely watched in both rural and urban settings. From fish vendors seeking hygienic stalls to households troubled by infestations, the ready-to-use spray could provide a convenient, reliable alternative to conventional repellents. Its safety profile makes it especially appealing for sensitive environments such as food preparation areas and animal shelters.
The granting of the patent not only validates the innovation but also enhances the reputation of ICAR-CIARI as a center of excellence in applied research. With commercialization underway, the fly repellent has the potential to set new standards in pest management while reaffirming the value of locally developed, eco-conscious solutions.
