Aphids must be controlled, because they are the main distributors of viruses between plants. Aphids can be treated successfully with Imidacloprid or Thiacloprid.

Spider mites do much damage on Brugmansia if the beginning of an infestation goes by unnoticed. Leaves, buds and young shoots dry up and fall off. First signs of the infestation are a a pale color of the leaves, the color of the surface appears to be silvery. The mites cover leaves and shoots with fine webs, the small reddish almost translucent mites can be seen with the naked eye. Treatment with pesticides like Abamection are successful but caution: spider mites are able to build up a resistance against pesticides. To avoid that, treatments with changing compounds are recommended.

Bugs can cause much damage especially on Brugmansia suaveolens and other Hybrids with a soft leaf texture. They suck with preference on the small leaves of the green shoots. The tiny punctures become larger with the increasing growth of the leaf, a narrow frame of dried up tissue encircles the punctures. The saliva of the bug is poisonous for the plant and causes a deformation of the leaves. Early Controls of the shoots is necessary to prevent with measurements further damage. Treatments with Thiacloprid are successful, the systemic compound protects the plant for appr three weeks.
