Which of the following is NOT a recommended step in solving a cockroach problem?

In addressing a cockroach problem, effective management relies on proactive strategies, and ignoring the sighting of insects undermines these strategies. Not responding to sightings can lead to an escalation of the problem, as it overlooks the important signals of an infestation and allows the population to grow unchecked.

The other strategies, such as sealing entry points, maintaining cleanliness, and monitoring populations, are all fundamental components of an effective pest management plan. Sealing entry points prevents new cockroaches from entering the environment, maintaining cleanliness reduces food availability, and monitoring populations helps assess the severity of the infestation and the effectiveness of control measures. Therefore, neglecting to act on insect sightings directly contradicts the principles of effective cockroach management.
