What is a common method used to manage ant populations?

Using bait stations around the home is a common and effective method for managing ant populations. Bait stations work by utilizing a combination of attractants and insecticides formulated to lure ants. Once ants take the bait back to their colony, they share it with other colony members, which leads to a significant reduction in the population. This method targets not just the visible ants but also those that remain hidden, providing a more comprehensive solution to the ant problem.

The other choices represent less effective or irrelevant methods. Pest exclusion techniques involve sealing entry points to prevent ants from entering a home; while beneficial, they do not directly manage existing populations. Setting off fireworks is unrelated and can be dangerous without impacting ant populations. Watering the lawn frequently may inadvertently provide a more hospitable environment for ants, as moisture can encourage their presence rather than deter it.
