Manuel Neuer increased his record without conceding a goal to 1108 minutes as Bavarians earned an emphatic victory over their promoted visitors
The Bavarian hosts went 3-0 ahead within 13 minutes, thanks to strikes from Mario Gomez, Franck Ribery and Bastian Schweinsteiger, after which time the match lost its competitive edge and took on the feel of an exhibition. Gomez completed his brace in the second half as he netted from the penalty spot.
It took no time for the hosts to find their form, and Gomez opened the scoring after just five minutes as he made a clever turn and fired inside the left post from 20 yards. Two minutes later, Jerome Boateng burst to the end line before crossing low, and Ribery tapped in from close range.
The result was put beyond a shadow of a doubt in the 13th minute when the Frenchman played the ball to Schweinsteiger at the edge of the box, and the vice-captain's low drive nestled itself into the back of the net.
Bayern could easily have entered half-time with a greater advantage, after the home side were unable to convert a number of chances. Ribery rounded goalkeeper Thomas Kraft after just two minutes but had his finish blocked, and the unmarked Muller missed a sitter from the centre of the box.
Gomez also managed to find himself through on goal, but was unable to beat Kraft, and Boateng had a low effort skid narrowly wide.
Hertha were rarely able to string a few passes together and their only sniff at goal came on 39 minutes as Raffael's attempt from distance corkscrewed high and wide.
The flow of play hardly changed after the break as Bayern continued to dominate possession, creating chances intermittently in what proved to be a semi-scrimmage. Philipp Lahm forced a stunning save from Kraft and Gomez just missed the far post before the striker completed his brace from the penalty spot.
Ribery was tripped inside the box to win the spot-kick, and Kraft almost managed a save, but could not quite redirect the ball wide of his post.
Hertha, utterly defeated after the hosts' early flourish, had little to offer going forward and made defensive-minded substitutions. Adrian Ramos replaced centre forward Pierre-Michel Lasogga mid-way through the second half, but the Colombian forward had little support and was unable to make an impact.
Other than the Mijatovic chance, the only noteworthy event late in the game was the return of Bayern striker Ivica Olic, who replaced Gomez in a brief run-out, ending a lengthy absence due to injury.
The result sees Bayern move five points clear of Monchengladbach atop the Bundesliga table as they prepare for Tuesday's Champions League showdown with Napoli. Hertha, meanwhile, remain 10th, with 12 points from nine games.
