Hedge infestation :(

Hi all, we have a bug problem on a hedge at the front of our house. There are small white things on the leaves and branches, and where there are a lot of these the leaves are dying (please see attached photos). I have used bug clear ultra a couple of times but the hedge itself doesn't look any better, and the white things are still there. Any advice on ways to remedy this would be really appreciated, thanks.

 

Euonymus scale / RHS
I think it might be this.

 

Thanks I think you're right, is there anyway I can save this hedge? It's caused a lot of leaves to fall off and I'm worried it might be too late to fix this.

 

Mine gets it every year. Some years worse than others but it lives on. I don't spray it as I can't really see it.
You may have killed the bugs with the a spray already and it's just their remains on the leaves. Try washing them off with a hose jet.
If not, you could give it another spray but follow what it says on the spray you have.

 

OK, thanks for the advice ☺️
