Spider Mites and Fungus Gnats on Nepenthes: Ortho Spray Safe, But Ventilate

NYC grower's Nepenthes (sanguinea, truncata, miranda, ventricosa) infested via neighboring croton/fittonia. Truncata/miranda in Nepenthes mix (drier) unaffected; ventricosa/sanguinea in peat/perlite (wetter) hit. Asked if Ortho fungus gnat/spider mite spray safe.

Answer

Yes, safe. Nepenthes tolerate standard insecticides well. Spray in garage/outside—dried residue fine, but odor strong. Repeat per label for spider mites (serious pest). Fungus gnats die fast; mostly a nuisance.

Why the Difference?

Peat mix stays wetter → fungus gnat haven. Nepenthes mix drains faster → less attractive. Spider mites prefer dry, warm—check all plants.
