Pamianthe headache

Curious if other growers of Pamianthe peruviana ever have issues with
invasiveness in a greenhouse setting? Despite best attempts to harvest
seed, it seems to happen every year a pod or two are missed and eventually
the seeds are blown all around the greenhouse. Thought this species was
supposed to be on the difficult side, yet they seem impervious to
herbicides and quite frankly I'm getting tired of ripping these out of
neighboring pots. Surely another grower on PBS has found a suitable method
for controlling this species? Just ripped another few dozen out -
