Many types of caterpillars can infest houseplants but rarely do they attack plants that are grown indoors.
The caterpillars vary in color from green, red, brown or black.
The signs of caterpillars is the presence of holes in the leaves; they are rarely seen as they eat up the plant and go into hiding.
Since these caterpillars are rarely seen, look for the caterpillars as soon as holes on leaves are observed. Once sighted, pick the caterpillars and destroy them.
