What is the term for a pesticide specifically used to repel or control birds?

The correct term for a pesticide specifically designed to repel or control birds is "Avicide." This term derives from "Aves," the Latin word for birds, and "cide," meaning to kill or to strike down. Avicides are formulated to target birds and assist in managing populations that may be detrimental to crops, food stores, or urban environments.

While insecticides, herbicides, and fungicides serve important functions in pest management, they target different types of organisms. Insecticides are designed to control insect pests, herbicides are used to manage unwanted plants (weeds), and fungicides target fungal pathogens. Each of these categories is distinct and does not include birds in their scope, reinforcing why avicide specifically addresses issues related to avian control.
