We have two lemon trees indoors by the bi-folds.

They are doing well apart from the aphids.

From recent Googling the biological controls are not available yet this
year.

Spraying advice doesn't seem to include Citrus in the UK.

Any recommendations?
More importantly, anything NOT to use?

They can be considered ornamental at the moment because they are showing
no sign of flowering.

Well we've seen a variety of ideas so far:-
My thoughts are as follows
Most insecticides have a time before harvest, even Organophosphorus was
2 weeks,
The chemical of choice in the US is found in Tumble Bug.
Whilst the plants are indoors, I'd move them outside to spray if you
can, then move them back inside.
If you are spraying with anything that may harm bead then don't spray
when in flower if possible, or if the plants are not to big then net
them for a couple of days after spraying to keep the bees etc. off them.
