Thanks Tom. Brought home some Melafix last night, dipped and basted one 11" rack of frags & small colonies. Probably 40-50 worms came off so I am hating life right now.
I am more comfortable dipping Bayer, but the Melafix seemed to dislodge them pretty well and the sticks look OK this morning with normal polyp extension. Another dozen racks to go.
Making some calls this morning to buy out all the six-lines in the tri-state area per a suggestion from @ctpeasy.
I think you’ll need to dip every rack on the same day to really be able to eliminate the problem.
