This large, reddish-brown cockroach has an interesting story behind it. The species originated in tropical Africa where it is common.
Most pest species of cockroach originate in Africa, with fossil records reaching back to the Carboniferous period, 250 million years ago.
It's believed that slave ships travelling between West Africa and the Americas for almost 200 years, brought it to Central America, the West Indies and the Southern United States.
Since those early days, it has used the boom in worldwide commerce to travel even more widely and become a genuine global pest species.
American Cockroaches In The UK
In the UK, American Cockroaches prefer locations with stable temperatures because they have adaptations for tropical conditions. For this reason, they prefer sites with high humidity and temperatures between 21°C and 33°C.
Kitchens, food businesses, bakeries, coal mines and even sewers are well-known haunts of this common pest.
These cockroaches inhabit premises throughout Ireland and the United Kingdom, from Scotland to the south coast of England.
The best methods of control are usually food-based baits that come as gels or pastes.
