What is considered a critical period for controlling aquatic pests?

The critical period for controlling aquatic pests is identified as early in the growing season before establishment. During this time, the conditions are most favorable for intervention because the pests are still in the early stages of their life cycle. By targeting them at this point, it becomes significantly easier to manage their populations and prevent them from establishing a foothold in the ecosystem.

If control measures are not implemented early, aquatic pests can rapidly grow in number and become more challenging to eradicate, as they may have already spread and outcompeted native species. Preventative measures taken before these pests establish themselves in greater numbers can help reduce environmental impact and maintain ecological balance.
