Yes, landscaping choices can significantly influence ant infestations. Plants that attract aphids, mealybugs, and scale insects, which produce honeydew—a favored food source for ants—can increase ant activity. Conversely, incorporating ant-repellent plants like lavender, marigolds, and mint may help deter ants, though some, like mint, require careful management due to their invasive nature. Additionally, using rock or gravel instead of mulch near your home’s foundation can reduce nesting sites, as mulch often provides favorable conditions for ants.
