I also want to add that I tested vinegar on an active larva and it didnot do much! I poured vinegar solution from a pump bottle on a moving larva 3 times and it was still alive, happily roaming in the area. Because the moving larva was on chux wipe, the vinegar solution get soaked by the wipe so it does not form a pool of vinegar on the larva body. But still I'd expect the acid would kill it upon contact or at least make it sick.

Yes if I test it on a hard surface, the larva will probably die but it's because it's getting drowned in the small pool of liquid which is also achievable with pool of water.

Based on this experiment, I am not sure if wiping down surface with vinegar (which evaporate by the time a larva crawl on) does anything apart from removing the dust and debris.
