Scientists create living mosquito repellent from human skin bacteria | New bacteria design reduces mosquito attraction by up to 64.4% and lasts over a week.


New bacteria-based mosquito repellent offers a safer, longer-lasting alternative to DEET.

Mosquitoes are notorious for their role in spreading a range of severe diseases, including malaria, dengue fever, and Zika virus.
