Genetic Study Uncovers Global Journey of German Cockroaches

Research traces the pest's origins to Southeast Asia and reveals its spread through historical trade and military routes.

German cockroaches evolved from Asian cockroaches around 2,100 years ago in Southeast Asia.
The species spread westward to the Middle East about 1,200 years ago, likely via trade and military movements.
Cockroaches reached Europe approximately 270 years ago, facilitated by European colonial trade routes.
Modern transportation and indoor plumbing helped them thrive in human environments globally.
Understanding their historical spread may lead to improved pest control strategies.
