how to get rid of scale bug

I have an infestation of scale on my 2 magnolias, a bay tree and an acer. The bugs appear on the stems and branches and have secreted a white substance which appears like a sticky white cotton wool. I have been blasting them off daily for about a week with high pressure hose, but they return but seem to be less daily. Should I just carry on with my treatment or is there an easier way??

Hose down the plants and then treat them with neem oil. It is both safe and effective against these pests. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm ^[1]
