The Exterminator outfit is a disguise that can be found in HITMAN™.
Worn by the two exterminator's from Bug SWAT. In this disguise 47 gains access to the backyard, the basement and most of Wing A except for the Security room and the Emperor Suite.
While wearing the disguise 47 can talk with the hotel manager and claim that he needs to inspect the Empreror Suite.This results in all NPCs temporarily leaving the suite and 47 gaining access until their return.
Jordan Cross will also leave the suite and move to the atrium. This allows the player to complete several challenges (Nutcracker; Oh Snap!; Oops! I Did it again!) than can't be done otherwise.
The Exterminator outfit appears in the following missions:
