What are the properties of an insecticide?

Insecticides are chemical substances designed to kill or repel insects and possess several key properties. They typically have a specific mode of action, targeting the nervous system, growth processes, or other vital functions of insects. Effective insecticides are often characterized by their potency, persistence in the environment, and selectivity for particular pest species while minimizing harm to non-target organisms. Additionally, they can be formulated for various application methods, such as sprays, granules, or baits, to enhance their effectiveness and ease of use.
