Harriers are now unbeaten in their last seven matches after comfortably dispatching mid-table Alfreton Town at Aggborough last night.
Cliff Moyo rose highest to head home a corner just past the half-hour mark and give Kidderminster the lead.
Harriers – who drew 2-2 at Farsley Celtic on Saturday – bagged their second of yesterday evening when Omari Sterling delivered a ball from deep and Ashley Hemmings headed home.
That made it 2-0 in the 71st minute – and the game was over as a contest three minutes from time when Hemmings got his second of the night.
He capitalised on a mistake in the Alfreton defence and had the simplest of tasks of finishing into an empty net.
Hemmings could have gone on to complete his hat-trick when he was unable to guide the ball into the net.
Harriers follow up with two more home games in the next week – against Curzon Ashton and Kettering Town.
