Which of the following is an effective method of cultural control for roaches?

Regular cleaning and sanitation is an effective method of cultural control for roaches because it addresses the underlying issues that attract these pests. Maintaining a clean environment helps eliminate food sources, hiding places, and conditions conducive to roach infestations. By regularly cleaning areas where food is prepared and consumed, as well as disposing of garbage properly, the likelihood of a roach population establishing itself is significantly reduced.

This approach not only prevents current infestations but also plays a crucial role in long-term pest management, as it disrupts the lifecycle of roaches by removing their access to necessary resources. Cultural control methods like this focus on changing behaviors and practices that create environments favorable to pests, making it a proactive strategy in pest management.

While insect traps can help in monitoring and controlling roach populations, they do not eliminate the conditions that attract roaches in the first place. Similarly, chemical pesticides may provide immediate relief but do not contribute to preventing future infestations when sanitation practices are lacking. Lastly, reducing humidity with heaters may impact roach activity, but it alone does not address food and nesting needs as thoroughly as regular cleaning does.
