Try lowering the ATP concentration 10 fold. For NEB ligase, I just dilute
the 10X ligase buffer with NEB#2 10X (or whatever is closest, although
ligase works in all RE buffers). Also do the ligation at RT as opposed to 16
degrees. Rouche also has a 5X concentrated ligase.

Our gene pool needs a little chlorine.
