New genomic study reveals the pest evolved 2,100 years ago in South Asia, debunking long-held misconceptions.

Researchers analyzed over 280 specimens from 17 countries to trace the German cockroach's origins.
The species likely spread westward 1,200 years ago with Islamic trade and military movements.
European colonial activities 390 years ago facilitated further global distribution.
German cockroaches pose significant public health risks, including spreading diseases and triggering allergies.
The findings highlight the species' adaptability and resistance to various insecticides.
