Check your VARROA levels.
That's the first thing I would do a alcohol wash good luck.

While I routinely replace comb, plenty of beeks take great pride in their old, black comb and have very, very good results using it. They also keep the varroa population under good control. THAT will be far more helpful to your bees than new comb.The queen likes new comb. If you have comb without honey in the brood box, move them up into the supers and put new frames with foundation in the brood box. If you have brood and honey, move half up to the supers and replace with new foundation. I find brood comb needs replacing at least every two years. You should notice a invigorated queen.
Fortunately I have no experience of verroa and want to keep it that way. Just quoting from my experience.While I routinely replace comb, plenty of beeks take great pride in their old, black comb and have very, very good results using it.
