Which of the following is NOT a step in the control of ants?

Using only chemical methods is not a step in the control of ants because effective ant control often requires an integrated pest management approach that combines multiple methods. Relying solely on chemical methods can lead to resistance in ant populations and may not address the root of the problem, such as nest location and colony size. Effective ant control typically begins with proper identification, as recognizing the specific species can influence the treatment method chosen. Locating nests is crucial for targeted treatments, and strategies such as baiting and perimeter barrier treatments are part of a comprehensive approach that can include both mechanical and biological methods, in addition to chemical controls. This multifaceted approach increases the effectiveness of preventing ants from reestablishing themselves in the treated area.
