What is an effective method for treating Pharaoh Ants chemically?

Setting up more bait stations after initial treatment is an effective method for addressing Pharaoh Ants because this pest is known for its difficulty in eradication due to its large colonies and tendency to relocate when disturbed.

Bait stations work by attracting ants to a slow-acting insecticide that they will carry back to their colony. This allows the poison to be spread among the colony members, ultimately leading to a more effective reduction in their population. After an initial treatment, placing additional bait stations can enhance the effectiveness of the strategy by ensuring that any surviving ants are still targeted and further diminishing their numbers.

This method aligns well with integrated pest management practices, emphasizing the importance of monitoring and continuous treatment to manage pest populations effectively over time. In contrast to the other options, which focus on direct application methods or drastic measures like complete evacuation, adding more bait stations continues to target the problem in a less disruptive and more strategic manner.
