Mealybugs and their damage to plant leaves

Mealybug Infestation and the Resulting Damage to Houseplant Leaves

Mealybugs are tiny pests that can wreak havoc on indoor houseplants. The infestation often starts with the fine webbing seen around the base of leaves or stems. Mealybugs attach themselves to the plant and feed on its nutrients, resulting in damage to plant leaves. They leave behind a white powdery residue that can easily be recognized as mealybug-infested plants.

Mealybugs damage plants by sucking out the sap from leaves, causing them to yellow and drop off prematurely. This can affect growth and development of new foliage as well, making it more vulnerable to other diseases or pests. Furthermore, mealybugs also secrete honeydew, which attracts ants and other insects to feed on plant juices and create a conducive environment for fungal growth.

To contain the damage from mealybug infestation, use organic insecticides like neem oil or horticultural soaps. Also, manually remove visible mealybugs with a cotton swab dipped in alcohol or soapy water. Additionally, wash affected plants with a strong stream of water or isolate them from other houseplants until they are treated.
