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.
