Which statement about cockroach management is true?

The statement highlighting the importance of moisture control for effective cockroach management is accurate. Cockroaches are attracted to environments that provide moisture, as they require water to survive. High humidity levels and available water sources make spaces more inviting for these pests. Consequently, implementing moisture control strategies — such as fixing leaks, ensuring proper drainage, and using dehumidifiers — plays a pivotal role in cockroach management by creating an unfavorable environment for them.

In terms of the other options, using only bait for control is an incomplete strategy since combining various methods, such as sanitation and exclusion, often yields better results. Additionally, while many cockroach species prefer humid environments, not all of them thrive under dry conditions. Lastly, cockroaches are known to be social insects; they typically live in groups and can often be found in colonies, which contradicts the notion of them being primarily solitary creatures.
