We have an ornamental tree in our garden and it is completely covered in white little dots. They look like eggs or larvae, but Iβve never managed to see them move.
This is in Spain in case thatβs relevant. More pics in comments.
I don't know if this will help, but I had to resolder the cables to the bed of an old printer and the iron I had just couldn't put out enough heat; the bed sank it all. I put it in the oven for a while, so that it was pre-warmed and the iron could melt the solder.
Probably using the kitchen oven where I cook wasn't a very good idea, but hey, I'm still alive.
