Nepenthes Scale and Sooty Mold: Insecticidal Soap for Scale, Ignore Mold

Black sooty mold on pitchers = feeds on nectar, harmless. Rinse off with rain/spray. Red spotting may be age-related.

Scale (likely hibiscus scale from Leilani plants): treat with insecticidal soap (potassium salts of fatty acids) in evening. Avoid pyrethrin combos. Repeat per label. Remove heavily infested pitchers. Check nearby non-carnivorous plants for scale.

Soap breaks down insect cuticle—resistance unlikely. Lowe's carries suitable brands.
