Treating Whiteflies/Aphids on Orchids and African Violets with Alcohol Swabs

Safe Application

Do NOT spray alcohol directly—it damages delicate leaves. Instead, dip cotton swabs in 70% isopropyl alcohol and touch only the insects on leaf undersides. Alcohol kills on contact.

Alternatives

• Witch hazel or nail polish remover (acetone-free) on swabs.
• Insecticidal soap labeled for indoor plants (test first).
• Strong water spray for orchids (not violets).

Prevention

Isolate new plants. Inspect weekly. Good air circulation reduces infestations.
