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!
The bugs might be scale and the oil should have helped if you had good coverage of the scale. I suggest that you take a sample of the plant leaf (frond) with the insects on it to your County Extension Office to let them identify them and prescribe the best management options. Their contact information is:
732 N 9 Street
DeFuniak Springs, FL 32433-3804

Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
