To control which cockroach, must chemicals be applied over a greater area of the building?

The brownbanded cockroach typically requires chemicals to be applied over a wider area of a building for effective control. This species tends to spread across different rooms and areas, often residing higher up in structures, which necessitates broader treatment coverage. They are more likely to be found in various locations, such as in furniture or behind wall hangings, as opposed to having a specific concentrated nest site.

In contrast, other cockroach species may have distinct habits that allow for more targeted applications. For instance, German cockroaches are often found in kitchens and bathrooms, where their populations can be localized, making control measures more effective when applied in those specific areas. Similarly, while American and Oriental cockroaches can inhabit various environments, their detection typically occurs in specific locations, allowing for more concentrated treatment.

Thus, the need for broader coverage in the context of the brownbanded cockroach arises from its dispersive nature within the building, emphasizing the importance of comprehensive application to ensure effective population control.
