Winter treatments with supers on.

[McGinty]

Hi everyone.
2nd year beekeeper here. 1st year with honey.
I have 3 hives and have given each 7 frames of honey back after their Autumn treatment (apivar strips) and back up fondant. I have the supers under the brood boxes.
I've been trawling the internet for information but am still confused. My questions are ...
Are there any winter varroa treatment options available to use with supers on? Can I reuse the drawn comb frames after?

Many thanks
McGinty

oxalic acid, either trickle or sublimation is the only sensible winter treatment, and yes, you can still use the shallows and the comb for honey supers next year.
