Scale Insects

Small, armored insects attach to the undersides or stems of the Phalaenopsis and secrete honeydew, a sticky waste product. This residue often attracts black sooty mold.

Very Common

How to confirm: Inspect the underside of leaves and leaf axils for small, hard, brown bumps that do not move.

Aphid Infestation

Soft-bodied aphids cluster on new growth and flower buds, excreting large amounts of sticky honeydew. This can cause distortion in the developing orchid leaves.

Very Common

How to confirm: Look for tiny, pear-shaped insects (green or black) near the tender tips of new leaf growth.

Mealybugs

These pests hide in the crevices of the orchid's crown and leaf junctions, leaving behind a sticky residue and white, cottony masses.

Common

3 Inspect the crevices of the orchid regularly and ensure the plant is in a well-ventilated area to discourage pest buildup.
warning

Excessive Liquid Fertilizer Residue

Over-application of water-soluble fertilizers can lead to salt buildup on the leaf surface, which may feel tacky or sticky when it dries.

Common

How to confirm: Check if there are white, crusty mineral deposits on the leaf surface along with the stickiness.
