This game was over before the half-time hooter with the defending champions showing no mercy as they ran in six tries as Wakefield simply had no answer.
Farrell got the ball rolling with the opening score and added a second before the break, while Zak Hardaker, Willie Isa, Jake Shorrocks and Jarrod Sammut also crossed to make it 34-0.
Ryan Hampshire managed to go in twice in the second half for Wakefield, either side of a length-of-the-field effort from Oliver Gildart, before Farrell raced away for his third of the night.
Wigan opened the scoring after just four minutes with Farrell steaming onto a short ball from Sam Powell to touch down. Hardaker converted to make it 6-0.
The Warriors extended their lead six minutes later with another attack down the left. George Williams, Gildart and Liam Marshall exposed some poor defending, before Hardaker used brute force to get the ball down. He converted his own try for a 12-0 advantage.
Wakefield were struggling to get in the game and they soon found themselves 18-0 down with Isa benefiting from a cross-field run from Williams to grab Wigan's third try inside 15 minutes.
Wakefield only had one real attack at Wigan's line in 40 minutes and that came to nothing. Wigan then exerted their dominance with three tries in the final 10 minutes of the half.
First, Farrell collected a short ball from Williams to grab his second, while Shorrocks collected an attempted short kick-off from Wakefield to race 60 metres. Sammut then went over on the hooter as he intercepted a pass from Jacob Miller to race away and score.
Trinity showed some improvement after the break and finally got on the score sheet as Miller sent a kick over the Wigan defence and Hampshire was on hand to touch down. Danny Brough converted but they trailed 34-6.
Bulgarian-born teenage prop Ethan Havard was handed his debut in the 47th minute and he watched on in awe as Gildart raced the full length of the field to score as Wigan hit the 40 mark.
Hampshire crossed over for his second of the game before Farrell raced away to complete his hat-trick, while Trinity had the final say as Max Jowitt finished off a nice passing move in the corner.
