Springtails are very difficult to control. It sounds like you have a good start on the areas you are treating. However, you need to go after them at the source - the lawn. Treating the entire lawn is recommended for Springtail control. It is also recommended to respray the lawn when necessary or at least every 3-4 weeks until the Springtails have subsided. There is not a sure cure for Springtails, regular treatments are the only solution. It doesn't matter which pesticides you use. Onslaught is a great product, better than Bifen. But as far as Springtail control goes, I would use the cheaper pesticide since regular treatments are going to be necessary.
You have to wait until the Springtails have "cycled out" before they begin to disappear. Sometimes this takes a few months. Keeping a constant chemical barrier down is the only way to get any kind of relief or control. Inside spraying is usually worthless and not recommended. Vacuum them up.
