Which component is generally used as a botanical insecticide?

The correct answer is that Avert is used as a botanical insecticide. Botanical insecticides are derived from plant sources and are generally considered to be more environmentally friendly and often less toxic to non-target organisms compared to synthetic insecticides. Avert contains ingredients that are extracted from plants, which allows it to function effectively against a variety of pests while maintaining a more natural profile.

In contrast, boric acid is a mineral that acts more like a stomach poison for insects, particularly cockroaches, rather than being classified as a botanical insecticide. Malathion is a synthetic organophosphate insecticide used against a wide range of pests; it is not derived from plant sources, making it fundamentally different from botanical insecticides. Nylar, on the other hand, is a growth regulator (an insect growth regulator or IGR), which inhibits the normal development of insects, and also does not fit the definition of a botanical insecticide as it is not derived from plants.
