Olive tree with black "spots"

I have a small OLive tree that developed black "spots" whilst indoors. I put it outdoors for the summer but the spots remain. They pick off quite easily but are increasing in numbers. We live in Essex and the plant remains outside in a sheltered position

i'm not clear what you're describing - are they insects, these black "spots"? where are they on the plant - on the leaves or stems?

They are mainly on the stems and I think they are insects but they just look like little round black spots. They are easy to remove but keep soming back.

Could they be something simple like blackflies - these could be present on new, soft stems particularly. And are they causing any damage to the plant?

They do not look like blackflies, They are round, the size of a pinhead and shiny.
They do not appear to do any damage to the plant but I am loathe to bring it back into the house for the winter months until I solve this problem. Many thanks for your continued help.

They are probably leaf scale insects and tend to attack weaker plants. Can you have a really close look at them ?
They can be sprayed with horticultural oil and water or sprayed with a systemic pesticide . They probably won't do much damage but the plant would be better off without them !

My grateful thanks for your advice. I shall certainly take it and, with fingers crossed, start spraying.
