However… the presence of ants often indicates another problem. That’s because ants feed on the honeydew emitted by aphids and mealybugs, insects that truly are a danger to your plants. Follow the ants’ movements and they will often lead you to a hidden invasion of truly nasty bugs.
A thorough treatment with insecticidal soap, repeated weekly for 3 weeks, will overcome the real problem! And you can thank the ants for showing you where the problem was!
