Scale insects are a real pest

I have just spent 2 hours checking all my trees after discovering that my large Chinese Elm was riddled with scale insects. I generally check my trees every month and there was no sign at the last inspection in May.

No sign of aphids, so the systemic must have done its job, but scale on most of my Chinese Elms, two of my maples and three of the cotoneasters.

I have removed any that i could see with a brush dipped in white spirit and applied another spraying of systemic insecticide.
