Thrips

Description

Thrips are small black insects, 1 to 2 mm long. The adults have two pairs of wings. Most thrips feed on plant sap and tissue, but there are also species that feed on fungi or wood, as well as predatory ones (feeding on the larvae and eggs of other small invertebrates). Some thrips are potential crop pests: besides the damage they do by eating plant tissue, they also spread viruses, bacteria and disease-causing fungi. These insects have even become a pest of technology, because they can get inside LCD screens, from which they are very difficult to remove.

Control

First rinse the plants under the shower in the bath, then spray them with an insecticide.
