Which types of pesticides kill target pests directly?

Chemical pesticides are specifically designed to kill target pests directly through a variety of mechanisms, such as disrupting their nervous systems, inhibiting their growth, or causing physiological damage. These pesticides can be made from synthetic compounds, which have been developed to be effective against specific insects, weeds, fungi, or other pests.

While biopesticides and biochemical pesticides can also play a role in pest management, they typically work through more indirect means. Biopesticides often use natural organisms or substances to control pests, and their action may not be as immediate or lethal as that of chemical pesticides. Biochemical pesticides may include substances that alter pest behavior or disrupt their life cycles rather than killing them outright.

Therefore, when the question focuses on types of pesticides that kill target pests directly, chemical pesticides are the most straightforward and direct answer, as they are formulated to achieve that specific outcome.
