Bay tree sucker insect

Hi everyone

my bay trees two standard loli pops have have a new pest to me (bay sucker) look like a mini aphid but gray and they make the edge of the leaf turn over like it’s bubbled.

how long has this been in the UK and best way to kill

I have 2 bays and they get a bit of it every few years.
It doesn't seem to affect many leaves, so I just remove the curled-up ones.

No idea how long it's been around, but I can recall it for about 30ish years since I've had bays, so probably been around a long time
