What is an example of a non-selective pesticide?

A non-selective pesticide is designed to control a wide range of pests without specificity for any particular target organism. Fumigants are a prime example of non-selective pesticides because they work by gasifying to penetrate various environments, targeting multiple pests, including insects and weeds, across various life stages. Their broad application capability makes them effective in controlling diverse pest populations.

In contrast, other options offered are more selective in nature or specific to particular pest types. Pheromones generally function in pest management by disrupting mating patterns rather than directly killing a wide array of pests. Botanical sprays are derived from plants and often target specific insects or diseases, while insecticidal soaps primarily affect soft-bodied insects. Therefore, these other choices do not fit the definition of non-selective pesticides like fumigants do.
