Do you have a rat problem?
Then there is only one person to call, Monty the Rat Extermination Specialist.
He is located on the Ironforge side of the Deeprun Tram. His brother, Nipsy, runs a rat kabob business on the other side of the Deeprun Tram. He starts a couple of quests, Deeprun Rat Roundup and Me Brother, Nipsy.
The world of Azeroth really does have everything you could need including pest control!
