Key Takeaways
- IIT Delhi scientists developed mosquito-repellent laundry detergents
- Fabrics washed with these detergents show massive reduction in mosquito landings
- The technology works on both smell and taste sensors of mosquitoes
- Patent filed, commercial products expected to launch soon
IIT Delhi researchers have created a revolutionary solution to India’s mosquito crisis by developing laundry detergents that repel mosquitoes. This breakthrough technology turns ordinary clothes into protective barriers against disease-carrying insects.
The smart detergents, available in both powder and liquid forms, represent a major advancement in the fight against mosquito-borne diseases like malaria, dengue, and chikungunya.
“We have developed smart detergents to protect people from dangerous mosquito-borne diseases. The products have been tested in a commercial laboratory and have proven effective at repelling mosquitoes,” said Prof Javed Nabibaksha Sheikh from IIT Delhi’s Department of Textile and Fibre Engineering.
Rigorous Testing Proves Effectiveness
Researchers used a “hand-in-cage” method where volunteers inserted fabric-covered hands into boxes containing hungry mosquitoes. The results showed fabrics washed with the special detergents experienced significantly fewer mosquito landings.
Mosquitoes actively avoided contact with treated fabrics, demonstrating the technology’s powerful repellent properties.
How The Technology Works
The active components in the detergents interact with fabric fibers during washing, creating surfaces that mosquitoes find unattractive. The formula targets both olfactory and taste receptors in mosquitoes.
“The active components work on both the smell and taste sensors of the mosquitoes,” Prof Sheikh explained. The protection renews with each wash, maintaining long-term effectiveness against mosquito bites.
Commercial Availability
IIT Delhi has filed a patent for the technology and expects commercial products to reach consumers soon. This innovation could make mosquito protection as routine as doing laundry.
The development marks a significant step forward in and public health protection across India.
