Pest Infestation
Common houseplant pests include spider mites, mealybugs, fungus gnats, scale, and aphids. Early detection makes management easier.
可能原因
Spider Mites
Why: Thrive in dry, warm conditions. Very small and often go unnoticed until damage is visible.
Signs to check: Fine webbing on leaves, tiny dots on leaf undersides, stippled or speckled leaves.
Mealybugs
Why: Sap-sucking insects that produce a white, cottony substance.
Signs to check: White fluffy clusters on stems, leaf joints, or undersides.
Fungus Gnats
Why: Larvae thrive in consistently moist soil.
Signs to check: Small flying insects around soil surface, especially when watering.
检查要点
- 1Inspect leaf undersides with a magnifying glass
- 2Check stem joints and new growth areas
- 3Look for webbing, sticky residue, or white fluff
- 4Note any small flying insects around the soil
处理方法
- Isolate affected plant from other plants
- Wipe leaves with a damp cloth for minor infestations
- Allow soil to dry between waterings for fungus gnats
- Consider neem oil or insecticidal soap for persistent issues
何时寻求帮助
- Infestation spreading to other plants
- Severe leaf damage or leaf drop
- Plant showing overall decline despite treatment
关键要点
Regular inspection is the best prevention. Catching pests early makes them much easier to manage.
