By drying out I mean just letting the trays dry out, not the media in the potsl. You never want roots of carnivorous plants to dry out. The Complete Insect Killer has a systemic insecticide (Imidacloprid) and a contact Pyrethroid insecticide. The Pyrethroid will kill any crawlers that might hatch from eggs. The adult mealybugs will get a dose of the systemic when they feed on the plants. Their waxy coat protects them from the contact insecticide. You could use some other contact insecticide like Neem Oil or Pyrethrim if you like.
Flush the pots a few weeks after your final drench - just top water the pots a couple times and discard the runoff (no trays). Then back to trays as usual.
Be sure to follow the advice from ICPS and trim and peel off as much of the dead stems on the crown. The less hiding places the more effective the treatments will be.
No problem. Mealybugs are very nasty and difficult to control. You may not even be able to eradicate them. If I find the root infestations have returned I'm just going to destroy the plants. That may make some of you shudder but they are only S. 'Tarnok' and easy enough to replace since it is being propagated from tissue culture.I apologize for asking so many questions. I'm a bit flustered never being in this position before...
Only when you drench the plants, once a month. Otherwise water as normal. Note: I have not used the 6x concentration on Nepenthes so I cannot tell you how they will react. The spray form appears to be harmless to Nepenthes.Forgot to ask, since I'm using the tray method for everything but the Neps does that mean I will have to be top watering every pot now?
