Aphid Infestation

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf undersides of your Imperial Green, secreting honeydew as they feed on plant fluids. This results in a persistent sticky film across the leaf surface.

Very Common

Mealybugs

Mealybugs produce a sugary excretion as they feed on the Philodendron's vascular system. While they are often identified by white cottony masses, their presence can cause a sticky residue on nearby leaves.

Common
