A rat trap outside Peter Dutton's office north of Brisbane was mistakenly reported to police as a "unknown item" on Thursday, prompting the bomb squad to be called to the scene.

The specialist officers gave the all-clear at the office of the federal member for Dickson, off Gympie Road in Strathpine, just before 1pm after uniformed officers first on scene were unsure whether it was safe.

Police were initially called about 11.25am and warned office workers not to approach the item.
