I just went through the Fox News coverage of the VP debate from 10/7/2020 - there is no fly on his hair that I could find. I did not look at every second but spent a bit of time looking at each time Pence spoke. NO FLY.
At 1 hour and 18 minutes I did see and hear Kamala Harris make the comment and giggle. But why no fly? If someone sees it please let me know at what time of the debate it showed up.
I watched the debate on Fox and saw the fly.
