Question about fixing squeaky floorboards without pulling them up

That glue trick is a total band-aid fix for people who don't want to do the job right. Squeezing adhesive into a dark gap from below is just guessing, and it makes a huge mess on your subfloor for the next person. That bond will fail with the first big temperature swing or when someone drags a heavy piece of furniture across it. The only real fix is still coming from above with a proper screw or a finish nailer into the joist.
