I have in the past had fungus gnats flying around the house. Hence thinking that it is a good possibility of what it is this time, and trying to get ahead of the little buggers this time. (Pun not intended) I've re-potted all of my Catts and my 1 Brass into hydroponic baskets from the Clear plastic orchid pots in an attempt to get better air flow, and a little better drying out between watering so that the bugs hopefully don't infest the new or treated media. I will hopefully soon get all of my Phals into similar baskets, though for some of the Phals being that they are recent rescues I am trying to hold off until I can get them a little better established and re growing in their current pots. Hopefully that helps fill in a little more of the info you might have been wondering about.
