Please can I have some advice on what these are and should I be getting them of or is there a spray I should use my tree seems heathy for now what course of action should take
They’re from code enforcement. They’ve come to inspect your wiring.
Until someone comes in with the correct answer, I’d blast them off with your hose.
I think they may be juniper scale insects. Google them and see if they look similar. I have a landscape juniper infested with themThey don’t seem to harm it but I am keeping by bonsai well away. At some point I will probably have to think about dealing with them, especially as I am going to use the big tree for airlayers.
Aphids. See the ant milking them? Blast them off with a hose like @BillsBayou says.
Thankyou very helpfull I think I can now clean them all
