Ant colonies can never thrive in soil with high moisture content. They prefer dry, undisturbed soil to build nests. Therefore, consistently watering your garden soil and even those untouched corners can disrupt the ants' trails and mounds, said Ed Dolshun of Catchmaster, a pest management company.

Sprinkling cinnamon or diatomaceous earth around the plant bases can help keep ants away. These act as a natural ant repellent while their organic nature does not harm the plants. Additionally, a 1:1 mixture of vinegar and water can also work to repel ants, but experts advise being careful it does not get on the plant foliage. 

While these pests can be a persistent nuisance in gardens, there are certainly a few benefits. Looking on the brighter side, ants help in soil fertilization as they bring in the dead foliage and insects to their underground labyrinth of nests, per the Almanac. Ants are a source of food for birds and other larger garden animals, making them important to the ecosystem.
