How bedbugs took over the world - a podcast by BBC World Service

How did bedbugs become a global concern? We examine why their unconventional reproduction methods are so successful, how bedbugs and humans even crossed paths in the first place and what public health has to do with nation building.

Also on the show, we look at why there's no human version of dog food, how conspiracy theories take hold, and the legal wranglings over an old Canadian oil pipeline.
