German cockroaches (Blattella germanica) originally come from Asia, specifically the region that is now India, Bangladesh, and Myanmar. Recent DNA and genetic studies trace their origins back about 2,100 years, evolving from the Asian cockroach (Blattella asahinai) when they adapted to living in human settlements.<\/p>\n
Despite their common name, German cockroaches are not native to Germany or Europe. Their global spread accelerated through human activity, travel, and trade\u2014particularly with the expansion of international commerce and colonial trade routes. Today, they are found almost exclusively in human-made environments and are rarely, if ever, found in wild natural habitats.<\/p>\n
They primarily infest buildings\u2014especially places with food, warmth, and moisture, such as kitchens, bathrooms, restaurants, and hotels. Their close association with people and quick reproduction has helped them become one of the world\u2019s most common and challenging household pests.<\/p>\n
