What is the role of flushing agents in pest control?

Flushing agents play a critical role in the control of pests, particularly in the management of cockroach infestations. Their primary function is to flush pests out of hiding places, encouraging them to come into contact with residual insecticides used in the treatment process. This is especially important for cockroaches, which tend to harbor in dark, concealed areas within structures.

By using flushing agents, pest control professionals can effectively supplement residual treatments, ensuring that more insects are exposed to pesticides. This combination often leads to greater effectiveness in managing and ultimately eliminating cockroach populations. The action of releasing pests from their hiding spots maximizes the efficacy of the primary treatment methods employed in the pest control strategy.

The other options, while related to pest control, do not accurately describe the specific use and function of flushing agents. They do not serve as the main method of pest elimination on their own or as attractants for traps, and they do not enhance the effects of natural predators. Instead, their primary purpose is to drive out pests for more effective treatment with residual insecticides.
