The Lancashire outfit have now gone nine games unbeaten in the Championship, but Bowyer felt that they were not clinical enough in attack to claim the three points.
"If you look at all the lads in terms of the performances that they've produced over the season, then they've not reached those standards that they know they can," he told Radio Rovers.
"We looked a little bit nervy, we passed it off when somebody might have taken that opportunity to shoot. We said before the game that there would be no easy match, we knew Yeovil would come to try and nick a point and they've done it.
"We haven't been cute enough in the final third today and that is it, we huffed and puffed. But we can't sulk, we can't feel sorry for ourselves. We'll regroup, we'll get the smiles back on the faces and we go again ready for Birmingham on Monday."
Blackburn are currently 10th in the Championship table, four points outside of the playoff places.
