well I think you'll agree, if there are eggs the adults were there and/or are still there somewhere, you'll want to keep looking. In the meantime you can decide how to treat them, I am not an outdoors grower so I am not sure how helpful I can be but I have read others use their hose to wash off bugs and you can also use citric acid to make a spray that will usually get rid of many bugs
give some time and I bet an outdoors grower will pop in and give you some suggestions.
