We have a customer that recently had the black worms coming up in his commode identified as "black scavenger fly larvae" or Sepsidae larvae. We are unfamiliar with this fly species. Would this infestation be treated like a drain fly infestation?
Well, Sepsids are more associated with feces and decaying plant materials than the wet organic sludge of the drain fly larvae, but it is possible that either could breed in the same unsanitary setting. And, since this is a commode it certainly could provide the proper breeding conditions for the larvae of Sepsids. I'm not certain myself that I would recognize the larvae of black scavenger flies, but those of drain flies are fairly distinctive in appearance.
