Probably as there are so many of them around the world!!
There are more than 5,000 different species of cockroach, and they can be found anywhere apart from the Arctic and Antartic.
They have white blood and can run up to a speed of 5.5 km/h, which is roughly the average speed a human walking.
Cockroaches have been around for millions of years and are tough little critters. They scuttle around spreading diseasea and are very difficult to catch and kill, in fact they are so difficult to kill that they’ve become famous as being the sole survivors of a nuclear holocaust.
A cockroach can actually live for up to a week even without it’s head!
