Fungus gnats help with feeding my carnivorous plants, but their larvae have become a problem in one bowl. Can carnivorous plants handle cinnamon in their soil? I have read that it helps control fungus gnats when added to the soil surface.
Yes, I have read about various chemical, bacterial, and layering of sand treatments... I would rather avoid the first two and apply the last after I get this infestation under control. Any other non-chemical ideas that are safe for carnivorous plants are welcome.
