White flying gnats?

Question

Good day,
My lovely pyracantha is being attacked by what looks like white/albino flying gnats. The shrub/tree is suffering, leaves being eaten/destroyed. When watering, I spray the shrub and hundreds of white gnat-like insects scatter only to return to the bush. Is there some organic spray/mixture I can make to combat this before I lose the shrub?
Thank you, I would be most appreciative,
Irene
