It looks good as a houseplant all year round and shows its low-maintenance side. But if you place little value on a suitable location and neglect care, you have to reckon with the fact that sooner or later there may be a pest infestation…

Leaf discoloration indicates pest infestation

Discolored leaves and leaf loss - symptoms of pest infestation

The radiant aralie can be infested by various pests. Most of the pests suck the sap from the leaves, weakening the plant over time. You can often recognize a pest infestation by lightened to yellow leaves, leaf loss and a gloomy overall appearance.

Susceptibility depends on the Schefflera species

Susceptibility varies by species. For example, the Schefflera actinophylla is highly susceptible to scale insects. The Schefflera arboricola and Schefflera elegantissima, on the other hand, are susceptible to scale insects as well as spider mites, soft-skinned mites and thrips. Basically, the following pests occur more frequently on the Schefflera:

  • scale insects
  • aphids
  • Mealybug
  • spider mites
  • thrips
  • soft skin mites

Render the pests harmless

Scale insects should be carefully scraped off with a knife. Aphids and mealybugs can be wiped off with a damp cloth. A strong jet of water can also help with aphids. It is then advisable to spray the plant with a solution of soft soap (€44.90) or washing-up liquid, preferably in combination with spirit.

Prevent pest infestation - strengthen the plant

Prevention is better than any form of control, which in most cases also weakens the plant or puts it under stress. The risk of a pest infestation increases enormously, for example, if the schefflera is exposed to warm temperatures and/or low humidity. The risk of this is particularly high in winter (heating air).

You can also prevent pest infestation by optimizing care:

  • pour generously and evenly
  • fertilize at regular intervals, but not in winter
  • repot if pot has become too small
  • Reduce or avoid stress on the plant altogether
  • Spray regularly with lime-free water


Only in an emergency should you use poisonous insecticides. It is better to use beneficial insects such as predatory mites beforehand and to count on their help.
