Citrus Mealybug Infestation on indoor citrus
What's Happening
Mealybugs (Pseudococcidae family) are soft-bodied insects covered in white waxy filaments that suck sap from citrus leaves, stems, and fruit. They reproduce rapidly in indoor conditions lacking natural predators, forming dense colonies in leaf axils and branch crotches. Heavy infestations cause stunted growth, yellowing, honeydew secretion leading to sooty mold, and secondary bacterial/fungal infections through feeding wounds.
How to Fix It
- 1
Inspect weekly: Check leaf axils, undersides, and stem joints
- 2
Manual removal: Dab mealybugs with alcohol-soaked cotton swab
- 3
Systemic treatment: Apply imidacloprid soil drench for severe cases
- 4
Horticultural oil: Spray neem oil or insecticidal soap thoroughly every 7 days
- 5
Isolation: Quarantine infested plants immediately to prevent spread
How to Prevent It
Inspect new plants before introduction; maintain moderate humidity; wipe leaves monthly; introduce beneficial insects in greenhouse settings
