What should be done first in response to consumer complaints of rats in the attic?

Conducting a visual inspection of the attic and adjacent areas for pest activity is the critical first step in responding to consumer complaints about rats. This initial assessment helps to confirm the presence of rodents and gather important information regarding their activity, such as nests, droppings, and potential entry points.

By thoroughly examining the area, a pest control professional can better understand the extent of the problem and the behavior of the rats. This information guides the development of an effective control strategy tailored to the specific situation, ensuring that any subsequent interventions, such as trapping or applying rodenticides, are appropriate and targeted. Addressing the issue without this foundational inspection may lead to ineffective solutions and could result in wasted time and resources if the underlying problem is not properly identified.

The other options, such as setting traps immediately, applying rodenticides, or informing the consumer about nesting habits, are actions that should follow the visual inspection. Without understanding the situation comprehensively, these steps could be misaligned with the specific needs of the infestation.
