Whiteflies on African Violets: Identification, Treatment, and Prevention

Marje's African violet showed white specks on leaves and pale green foliage. Photos confirmed whitefly infestation—tiny insects that suck sap and excrete sticky "honeydew."

Identifying Whiteflies

Adults are tiny white flying insects; nymphs appear as stationary white specks on leaf undersides. Honeydew residue makes leaves sticky and can host sooty mold. Infestations spread rapidly between plants.

Treatment Steps

1. Isolate the infected plant immediately
2. For light infestations: dab each insect with alcohol-soaked Q-tip
3. For heavier infestations: spray insecticidal soap (follow label)
4. Alternative: neem oil (see Optimara's whitefly guide)
5. No soil treatment needed—whiteflies stay on foliage

Prevention

Inspect new plants thoroughly. Quarantine additions. Maintain good air circulation. Whiteflies thrive in warm, dry conditions.
