What is an attractant?

An attractant is specifically defined as a substance that draws pests towards a particular area, typically to facilitate their capture or trapping. This is crucial in pest management strategies where attracting pests to traps can help in monitoring populations or reducing their numbers effectively.

Other options suggest functions that are contrary to the purpose of an attractant. For instance, substances that repel pests would serve to keep them away rather than attract them, while products focused on prevention would also not be aimed at drawing pests in. A chemical that enhances plant growth pertains solely to agricultural practices rather than pest management, further demonstrating that the correct answer is indeed the substance that serves the function of drawing pests for trapping.
