More Ways to Keep Argentine Ants Out of Your Home:
Caulk cracks and crevices around foundations that provide entry from outside using silica aerogel for long-term control combined with pyrethrins for more immediate effects. Ants may be using wires and pipes to enter and travel to their destination so check utility service entrances for cracks and repair as needed. Also, eliminate indoor cracks and crevices in kitchens and other food preparation and storage areas.
Rinse out empty soft drink containers or remove them from the building. Thoroughly clean up grease and spills immediately. Remove garbage from buildings daily and change liners frequently. Look for indoor nesting sites, such as in potted plants. If ants are found in potted plants, remove the containers from the building, then place the pots for 20 minutes in a solution of insecticidal soap and water. Ants-be-Gone Recipe: two tablespoons of insecticidal soap per quart of water. Submerge the potted plant so the surface of the soil is just covered by the water-soap solution.
Outdoor ant nests may be associated with ornamental trees and shrubs that support large populations of honeydew-producing insects such as aphids, soft scales, mealybugs or whiteflies. So, avoid planting such trees and shrubs next to buildings and keep plants, grass, and mulch several inches away from the foundation of buildings because ants will use these materials for nests.
