Estimating the exact number of cockroaches in the world is nearly impossible due to their vast numbers and widespread distribution. However, it’s believed that there are trillions of cockroaches globally, spanning over 4,600 known species.
Cockroaches thrive in a variety of environments, from tropical rainforests to urban areas, and are incredibly adaptable. The most common species that humans encounter, such as the German cockroach or the American cockroach, live in human-inhabited areas. These species, however, represent only a tiny fraction of the total global cockroach population.
Given their ability to reproduce quickly and survive in harsh conditions, cockroaches are among the most numerous insects on the planet.
