Why is it important to know the life cycle and behaviour of pests?

Understanding how pests grow and behave helps you hit them when it matters most and use the right control method. Different life stages—eggs, larvae, nymphs, adults—often respond differently to treatments, and pests may hide or feed in specific places. Knowing the life cycle and behavior lets you target the vulnerable stage, choose the most effective tool (chemical, biological, or cultural control), and apply it at the right moment. That leads to better control with less waste and reduces the chance of resistance. The other points—identifying preferred hosts, calculating how much pesticide to buy, or guessing by color—don’t directly guide when and how to treat, which is why this concept matters most.
