Mealybugs in Garden – Identification, Prevention & Control Guide
What Are Mealybugs?
Mealybugs are small, soft-bodied insects covered with a white, cotton-like wax. They feed on plant sap and are commonly found on stems, leaf joints, and undersides of leaves.
They weaken plants by sucking nutrients and produce sticky honeydew, which can attract ants and lead to fungal infections like sooty mold.
How to Identify Mealybugs
- White cotton-like clusters on plants
- Sticky residue on leaves (honeydew)
- Slow plant growth
- Yellowing or wilting leaves
- Ant activity around plants
Damage Caused by Mealybugs
- Weak and stunted plant growth
- Leaf drop and yellowing
- Reduced flowering and fruiting
- Sooty mold growth
- Severe infestations can kill plants
Why Mealybugs Spread Quickly
Mealybugs reproduce rapidly in warm and humid conditions. They hide in plant crevices, making them difficult to detect early.
They spread through infected plants, tools, and even wind, making early control essential.
Plants Commonly Affected
| Plant Type | Examples |
|---|---|
| Indoor Plants | Succulents, money plant, orchids |
| Vegetables | Tomatoes, peppers |
| Fruit Plants | Citrus, mango |
| Flowers | Hibiscus, roses |
