American cockroach

The American cockroach is the largest species of common cockroach, and often considered a pest. None of the Periplaneta species are endemic to the Americas; despite the name, P. americana was introduced to the United States from Africa as early as 1625.They are now common in tropical climates because human activity has extended the insect's range of habitation, and global shipping has transported the insects to ports around the globe - where they have thrived.
