Using augmentation in a biological pest control strategy has limited effectiveness because:

The effectiveness of using augmentation in biological pest control strategies is often limited because beneficial organisms tend to leave the treated area shortly after their introduction. This can happen due to various factors such as environmental conditions, lack of suitable prey or hosts, and competition with other organisms. When these beneficial organisms do not establish themselves in the new environment, the intended pest control effect diminishes since their population does not sustain itself, leading to a temporary impact rather than a long-term solution.

Focusing on the concept of augmentation, the technique relies on introducing beneficial species to control pest populations, but if those species do not remain within the target area, the overall impact on pest control is significantly reduced. Their mobility may result in a quick dispersal before they can effectively reproduce or establish, thereby constraining the efficacy of this strategy.
