My flying dragon citrus tree

My flying dragon citrus tree

I'm terrified! My flying dragon citrus tree has developed these brown scaly things that I imagine are scale bugs, and is slowly yellowing in the leaves and, I think, dying. My mint plant has just died of an aphid infestation that I tried to fix with the detergent method, but I couldn't find a good amount of soap-to-water ratio and it shrivelled up and died. Is there anything I can do about the scale? Sprays, home remedies? And how much soap am I supposed to use when I'm spraying aphids? Please help! Thank you so much!
