What's eating my tea plant?

Tea tortrix moth (Homona magnanima and related species)

Signs: Rolled or tied leaves sheltering caterpillars that skeletonise foliage from inside the roll

Control: Hand-pick leaf rolls and destroy; Bacillus thuringiensis (Bt) spray for edible-safe caterpillar control

Tea scale (Fiorinia theae)

Signs: White scale colonies on leaf undersides causing yellowing and stunted new flush

Control: Neem oil or insecticidal soap spray at crawler stage; safe for edible plants when applied before harvest flush

Aphids (various species)

Signs: Colonies on young shoots curling leaves and excreting honeydew that promotes sooty mould

Control: Strong water spray; insecticidal soap; beneficial insects — avoid broad-spectrum insecticides on edible plants

Vine weevil (Otiorhynchus sulcatus)

Signs: Grubs destroy roots of container-grown plants; adults notch leaf margins at night

Control: Biological nematode soil drench (Steinernema kraussei) in late summer; physical barriers around pots

tea plant pests — FAQ

What is eating my tea plant?

The tea plant (Camellia sinensis) shares pests with ornamental camellias but also attracts caterpillars and leafhoppers as an edible crop. Tea tortrix moth, aphids, and scale insects are most damaging. For edible use avoid systemic pesticides — use neem oil, insecticidal soap, or hand-picking instead.
