If you found no adult worms and the small transluscent 'worms' were all
about 2-3mm long with a blackish gut line visible, then the chances are
you have an infestation of Fungus Gnats. The adults look like small
fruit flies that flitter around from pot to pot. They thrive on the
moist conditions in which many CP's grow. The larvae also spin webbing
over the soil surface. If the webbing is evident then you have a Fungus
Gnat problem. The larvae can be very destructive!
