RAMPANT Middlesbrough scored five on a humiliating afternoon at The Den.
Boro's early pressure finally told when Jelle Vossen hit a stunning dipping volley to open the scoring before Patrick Bamford drilled in a second.
Vossen made it 3-0 before completing his hat-trick with a simple finish from inside the box on the stroke of half time.
With the points in the bag, the visitors eased off in the second half but, seconds after Scott McDonald pulled one back, substitute Kike slammed in a fifth.
This defeat was Millwall's heaviest under Ian Holloway and leaves them two points above the relegation zone ahead of next Friday's televised trip to Brighton.
Holloway made three changes to the side that started at Bournemouth with Ricardo Fuller, Jack Powell and Andy Wilkinson coming into the side.
Millwall lined up in a 3-4-1-2 formation with Shaun Williams dropping back into defence alongside Alan Dunne and Byron Webster.
Holloway had called for a high-tempo, energetic performance but his team were miles off the pace from the first minute.
Boro thought they'd taken the lead in the fifth minute when Vossen's header hit the inside of the post but David Forde prevented the ball from crossing the line.
Forde denied Vossen again from close range before Adam Reach shot wide at the far post as the visitors came forward at will.
And they broke the deadlock in the 21st minute when Vossen controlled Daniel Ayala's pass and lofted a half-volley over Forde.
Bamford was given far too much lexapro without prescription time and space inside the area to make it 2-0 and Vossen was totally unmarked when he tapped in the third.
It got even worse for Millwall before the break as Bamford's shot deflected into the path of Vossen, who rolled the ball into an empty net to complete his hat-trick.
The half-time whistle prompted a chorus of boos from the home fans, many of whom headed straight for the exits with their side 4-0 behind.
Holloway brought on Magaye Gueye and Danny Shittu at the break and the Lions, who could hardly have been any worse, improved marginally in the second period.
Bamford, though, missed a sitter 60 seconds after the restart, firing wide after intercepting Scott Malone's attempted header back to David Forde.
Lee Gregory hooked a rare Lions chance over the bar before Gueye's goal-bound shot was deflected behind for a corner in the 52nd minute.
Bamford spurned his second good chance of the half when he inexplicably spooned Albert Adomah's centre over the bar from close range.
After Shaun Williams had a shot saved, McDonald pulled a goal back when the ball sprang loose in the box and he fired high into the roof of the net.
But conceding brought Boro back to life and they went straight down the other end and restored their four-goal advantage, Kike scoring off the post from 20 yards.
Bamford and Emilio Nsue both wasted chances to make it 6-1 in the closing stages but Boro emphatically cemented their position in the top six.
