I am at war with aphids and ants. You have to kill the Queen ant . I still have a nest somewhere. I do soil drench with spinosad where I think they are. To locate the nest I put sluggo snail bait down. Then follow them home. They seem to love it. I am gaining some ground in the battle. Purecrop 1 seemed to get the aphids population way down after I hosed them off my tomatoes and peppers. I am dealing with pavement ants. The first drench I did my whole outside veg. garden. My soil is a mix of pro mix , some choir, native soil and compost. Ants and fungus Nats love it.
