What's eating my bow bells cattleya?

Bow Bells Cattleya, a classic white hybrid, faces the standard Cattleya indoor pest threats: scale insects and mealybugs in sheaths, spider mites in dry air, and occasionally thrips targeting the pristine white blooms. Inspect monthly, strip old sheaths, and treat early — pest damage to white petals is especially visible.

Tan or brown bumps on pseudobulbs and leaf undersides; honeydew residue and reduced bloom vigor Remove with alcohol-dipped cloth; treat with horticultural oil spray at 3-week intervals; inspect roots when repotting

White cottony colonies in sheaths, at rhizomes, and on new growth; weakened and slow-growing leads Dab with isopropyl alcohol; apply neem oil every 7 days for 3–4 rounds; remove dead sheaths that harbor pests

Silver streaking, brown edge burn, and petal distortion on white flowers — damage is very obvious on light-colored blooms Remove damaged flowers; apply spinosad spray to foliage and spikes pre-bloom; use blue sticky traps to monitor levels

Fine yellow stippling across leaf surfaces; webbing between sheaths in low-humidity heated rooms Mist and raise humidity; wipe leaves with a damp cloth; apply insecticidal soap or neem oil spray weekly
