The stars of sitcom Scrubs live in fear on the set of the medical show, because the derelict hospital it's shot in is infested with thousands of rats.

The show is filmed on location at North Hollywood Medical Center, which was abandoned in 1998 and has been used in a number of TV shows and movies, as well as being home to colonies of rodents.

Scrubs creator Bill Lawrence describes the hospital as the "worst" place he has ever filmed, telling AOL, "The rat infested hospital where we shot Scrubs - we encouraged people to bring dogs to fight off the vermin."
