I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I am not familiar with the bug you are describing. The remedy of spraying periodically is probably your best option. I suggest you take a sample if the insects to your County Extension Office and see if they can identify them and if necessary prescribe an appropriate remedy.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
