The Clarets have scored just twice in their last four games across all competitions, with one of those coming in extra time and the other provided by defender James Tarkowski in a 3-1 Premier League defeat at home to Watford on Sunday.
Burnley wasted a number of good chances during that loss to the Hornets, and Dyche acknowledged that his side have so far been lacking a telling piece of quality in the final third.
"We've got to have more fire to go and score a goal because we got in some top-class positions and dominated large parts of the play," he told reporters.
"Of course people want to score a goal but it's [about] sprinting into the box, the intention that nothing is going to get in the way, that willingness and demand to arrive early and to read the play better.
"That moment...that little killer moment is what we're still trying to find as a group."
Burnley face away trips to take on Olympiacos and Fulham over the next week.
