These ants are found feeding on seeds, and often are associated with aphids and mealybugs which are excreting honeydew. When crushed, they give off a characteristic lemon-verbena odor. They are common soil-inhabiting species that tend mealybugs and aphids on the roots of plants. The secret of success in controlling an ant infestation is to locate and destroy the nest, including the queen and her young. Attempt to trace the ants' line of march from the food source to the approximate nest location.
Boiling water can be effective for a few mounds, especially when the ants are swarming.
Careful spot- chemical treatments of ant hills with an approved insecticide will help reduce the ant population. If the entire lawn is treated, water the lawn immediately to wash the insecticide into the soil. Do not allow children to play on the grass until the chemical has been washed in and the grass has dried. Follow label directions carefully for each treatment.
