The tick hangs out wherever there are grazing animals or humans. This little guy has cool design features that have been helping him suck blood for 146 million years. But like any parasite, he's just doing his job. Creepy Crawlies are slimy, squashy, stingy little pests, or so we all think, but in this series the insects invite us into their world to set the record straight. Each episode stars a different insect, who tells us all about where they live, what jobs they do, how they survive in such dangerous places and how we humans have got Creepy Crawlies all wrong!
