Since I did dispose of the bulb in a half filled trash can filled with matted grass I was easily able to reassess the bad bulb. I took 4 of the best scales that I already peeled off yesterday and cut off any top rotting portions and soaked it in the bleach solution so I will put them in some damp sphagnum tomorrow. Of the rest of the bulb I was able to observe the bugs. They are white, small as a pin tip and they actually move pretty quickly. From googled pictures of "bulb mites" I'm not sure if I can positively ID them as such. From online photos they appear a little bulbous and seem to be behaving well for the photographer. In my case the bugs seem very small and were moving fast. That said I'm not sure if I can positively ID them as bulb mites even though I've titled this thread as such. Either way, it's a little disconcerting to plant what looked like healthy bulbs that rotted away.
