"Back half of the second period, we were putting some shifts together," Larsen said. "Their power-play goal took the wind out of our sails."
Sebastian Aho made it 4-1 at 7:05 of the third period with a power-play goal. He has six points (three goals, three assists) in a four-game point streak.
The Hurricanes were 3-for-6 on the power play. The Blue Jackets were 1-for-4.
"You get that many penalties you are shooting yourself in the foot. You've got to play them 5-on-5," Larsen said.
Trocheck scored on a backhand at 16:13 to make it 5-1.
"I thought the special teams were big," Carolina coach Rod Brind'Amour said. "We killed a lot of penalties and then we got some power-play goals, which was huge, but I didn't love our overall 5-on-5 game. We just had too many turnovers, which led to some really good chances for them."
