What's eating my sarracenia rubra?

Sarracenia rubra, the sweet pitcher plant, is a hardy carnivore that resists most pests when grown well, but aphids are the most reported problem — distorting new pitchers in early spring and autumn. Mealybugs and scale can hide near the rhizome and trap folds. Fungus gnat larvae occasionally attack roots in overly wet media.

Sap-feeding colonies on emerging pitchers cause characteristic twisting and contortion of new leaves as they develop. Spray with a pyrethrin-based insecticide (canola oil + pyrethrin mix) covering all surfaces; treat twice, one week apart. Avoid systemic insecticides.

White cottony masses or hard brown bumps found in the folds of pitcher traps and near the rhizome; growth slows and sooty mould may follow. Remove manually with an alcohol-dampened cotton swab; apply insecticidal soap spray to the affected area and repeat weekly for 3–4 weeks.

Larvae feed on roots and rhizome tissue in saturated peat, causing unexplained wilting or poor pitcher development. Apply Bti (mosquito dunks) dissolved in distilled water; drench the medium and repeat in 7 days. Ensure the tray-water method does not keep media permanently waterlogged.
