What can one do when a pesticide doesn’t prevent the onslaught of an infestation of a certain type of insect? Isn’t a pesticide supposed to stop pests? Pests are small insects that eat your crop or damage your furniture and some of them can even infect you. A pesticide is a cocktail of dangerous chemicals that can kill an insect or pest. But off late reports have been showing that most pests have become immune to certain pesticides and insecticides. How can this happen? The explanation is actually very simple. Evolution, evolution is the reason as to why these pests are now immune to substances that ones used to drive them or kill them. The pesticide enters their life cycle and all the new underlings have a certain amount of this pesticide before they are even born. This means that their body naturally reacts to this and develops an antibody for this, making it immune to the pesticide. The main reason as to why this is happening is because we use or rather overuse pesticides. We feel that a good heavy spraying of this on the crops will prevent everything. But the truth is that the crop gets damaged and the pest becomes immune to the pesticide in a short span of time.
