Pest identification
What's eating my bilimbi?
Fruit flies
Signs: Larvae rot the flesh of developing fruit; infested fruit drops prematurely or is unusable at harvest.
Control: Use pheromone or protein-bait traps; remove fallen fruit promptly; harvest at the earliest ripe stage.
Scale insects
Signs: Waxy or armored bumps on stems and branches; sap loss weakens the tree over time.
Control: Horticultural oil spray; scrape off light infestations; introduce predatory beetles.
Aphids
Signs: Clustered on young shoots; distorted growth and sticky honeydew leading to sooty mold.
Control: Water jet to dislodge colonies; insecticidal soap or neem oil for persistent infestations.

Bilimbi pests — FAQ
What is eating my bilimbi?
Bilimbi is relatively pest-resistant but shares carambola's vulnerability to fruit flies, which ruin the small sour fruits from the inside. Scale insects, mealybugs, and aphids occasionally build up on stems and new growth, especially when trees are stressed. Prompt fruit harvest, fallen-fruit removal, and neem oil sprays address most problems that arise.
