I have done some checking and these little 'bugs' are NOT whiteflies or aphids. The are attaching themselves to the leaves.  Since my original post, we have tried Eight and it has done nothing.  attached is a picture of a leaf that is not covered in them but has them.

Also my email stated that I would be contacted 'as soon as possible'.  It's been over a week and just wondering what is the time?

Thanks for your follow-up information. The presence of sooty mold (the black fungus) which forms on honeydew (the high sugar content excrement) is indicative of the presence of some type of sucking pest. It is highly likely the insecticide you're applying IS effective but with the quick turnaround from eggs to feeders, there are successive generations. Another possibility is they are flying in from other plants. No insecticide kills eggs, so treating once a week for a period of 4 weeks will be necessary to break the cycle. Please feel free to collect a sample to take to your local Extension Office for more information.
