The only way to control pests is not to use chemical pesticides, biological control is a method in which the population of pests is reduced to a minimum by using a pathogen or a competing insect (parasitoid, predator, pathogen, antagonist or microorganism). To the farmer or the environment.

Biological control is an economically optimal method. According to a study, it is estimated that in this method, programs with complete success return 32 units of profit per unit of capital. With biological control, one of the principles of integrated management, or IPM, is an ecosystem-based approach that aims to prevent and reduce long-term pest damage in the farm and garden. With biological control, we also get closer to IPM goals.
