If we talk about the best method to opt for insect control, it will be using the biological method. This technique is quite safe for the plants and mainly used in greenhouses. However, you can practise this pest controlling technique outdoors too. To control pests biologically, natural enemies of the pest such as parasites, pathogens, and predators are introduced that geographically interfere with their ability to breed. It will also interfere with them to infect the pests with a fatal bacterial disease. This method is considered the best method to prevent your plants from getting harmed by insects. Also, the success of the process completely depended on the correct usage of appropriate species under proper conditions.
