Yellow Scale on Daphne Leaves

I have sprayed with white oil to no affect. Could you please make a suggestion? The scale is yellow and quite flat. It appears on the back of the leaf but shows through to the front by way of a small yellow blotch.

Give the insecticide some time to work. You may also want to look into using neem oil, which is very effective on this pest as well. These articles will help:

Also, scale tends to attack plants that have something else weakening them. Apply some fertilizer to the plant and make sure it is getting enough water.
