scale insects on Monstera Deliciosa
Quick answer
If your Monstera Deliciosa has scale insects, the most likely cause is: Scale insects (Coccoidea) appear as small brown or tan bumps attached to stems and leaf veins. They have a protective waxy coating that shields them while they feed on plant sap. Soft scales excrete honeydew; armored scales do not. Heavy infestations cause yellowing, stunted growth, and leaf drop. Scales often cluster on stems and leaf undersides.
Start here:
- 1. Scrape off visible scales with fingernail or dull blade
- 2. Apply 70% rubbing alcohol with cotton swab to individual scales
