Common pests on lady palm

Spider mites (Tetranychidae)

Spider mites are tiny arachnids that can appear as fine webbing on the undersides of leaves. Signs include small yellow or pale spots, leaf discoloration, and a dusty appearance. Spider mites thrive in dry, warm conditions. Regularly check the undersides of leaves, especially if the air is dry or the plant is near a heat source.

Scale insects (Coccoidea)

Scale insects look like small, brown or gray bumps on stems and leaves. They feed on plant sap, which can cause yellowing, sticky residue (honeydew), and general decline. Infestations often start on the lower stems and can spread if not addressed.

Mealybugs (Pseudococcidae)

Mealybugs are soft-bodied insects covered in white, cottony wax. They cluster in leaf axils and along stems. Symptoms include sticky leaves, stunted growth, and visible white patches. Mealybugs can spread between plants if not controlled.

Symptoms and damage

• Yellowing or mottled leaves
• Sticky residue (honeydew) on leaves or nearby surfaces
• Fine webbing, especially on leaf undersides
• Visible insects or bumps on stems and leaves
• Leaf drop or slow growth

Prevention and monitoring

• Inspect new plants before introducing them indoors.
• Check the lady palm regularly, especially the undersides of leaves and stem bases.
• Maintain moderate humidity and avoid letting the soil dry out completely.
• Remove dust from leaves with a damp cloth to discourage pests.
• Isolate affected plants to prevent spread.

When to seek professional help

If pests persist after repeated manual removal or if the infestation is extensive, consider consulting a professional for further assessment. Avoid using chemical treatments without proper guidance, especially indoors.
