What specific type of animal control is managed by avicides?

Avicides are specifically designed to manage and control bird populations. These substances are formulated to either repel or directly kill birds, which can be necessary in situations where bird populations pose health risks, damage crops, or create hazards in urban environments. Avicides work by targeting the biological systems of birds, making them effective for controlling species that may be problematic in various settings.

Focusing on other types of animal control, such as reptiles, fish, or insects, does not involve avicides, as those categories typically require different methods and substances tailored to their specific biological needs and behaviors. For example, reptiles may require different trapping or exclusion methods, fish control often utilizes nets or traps, and insect control usually involves pesticides designed for insects but not for birds. Hence, the direct association of avicides with bird control makes the choice correct.
