Which method is NOT effective for pest control?

The method that is not effective for pest control is using non-targeted insecticides. Non-targeted insecticides can harm beneficial organisms and disrupt the ecological balance within the environment. This means that while they may kill some pests, they can also eliminate predators or parasitoids that naturally regulate pest populations, potentially leading to an increase in pest numbers over time.

Effective pest control methods focus on responsible practices that consider the overall ecosystem. Manual removal, for example, allows for the direct elimination of pests without the risks associated with chemicals. Maintaining cleanliness helps prevent pest infestations by removing food and shelter sources, while employing biological control agents promotes a natural balance by utilizing natural enemies of the pests, such as predators or pathogens.
