What type of product is used to force insects out of hiding?

The correct choice is a flushing agent because it is specifically designed to drive insects out of their hiding places, making them more accessible for control measures. Flushing agents typically contain active ingredients that create an environment or stimuli that insects find uncomfortable or threatening. This prompts them to leave their concealed areas, allowing pest management professionals to more effectively target and eliminate the pests.

Pheromones, while they can attract or disrupt insect behaviors, do not force insects out of hiding but rather influence their activities and movements. Repellents work by keeping insects away from areas or individuals, but they do not actively drive them out of their hiding spots. Sticky traps capture insects but do not have the function of forcing them out; instead, they rely on the target insects wandering into the trap without any active stimulus to leave their hiding places.
