I suspect you have more than one sort of bug/caterpillar doing damage
here. In mid-summer UK you could just put the citrus plants outside
and spray with diluted washing up liquid to discourage the infestors.
Leaving them outside will allow birds and ladybirds to pick off some
of the unwanted visitors. Not a cure but a considerable improvement.
Just remember to water them a bit more frequently than indoors and
they will thrive. And bring them in before any risk of frost.

It looks to me from this picture like there is an infestation of red
spider on the older leaves (absolutely tiny ~0.1mm need a magnifying
glass to see the insects webs may be obvious). Silver pinprick damage
on old leaves and lack of vigour in new ones - the web might be
visible but you need a magnifying glass to see the pests.

BTW Don't put a recently sprayed plant in direct sunlight for a couple
of days. Wetting agents damage the surface waxes and the poor thing
can dessicate very quickly. I nearly killed a culinary Bay tree that
way.

Some mobile pest like meally bug is chewing at the leaves (leading to
deformed nibbled young leaves). Look under leaves for fluffy white
patches and treat with a small paintbrush dipped in meths. Same for
caterpillars. They are probably 1-2mm across.

Hope this helps - good hunting!

Martin Brown

i keep seeing ear wigs on the plants and ants? could this be the problem, ive not seen anything else? i leave the plants outside all summer and am buying a mini green housing for the winter. i tried washup liquid yesterday, just some cheap tesco home brand stuff, i will check them when i get home from work.

No. They are harmless.

Ants suggests to me you also have Scale Insect on the plants, a very common
pest on Citrus. The Ants will be "milking" the insects for the honeydew.

If it's scale insects, scrape them off with a blunt knife. Tedious,
but it works.

First I'm absolutely sure that you don't have scale insects because
you'd have seen them (and so would I on your pictures), they're flat,
as big as my little finger's nail, brown, and are seriously stuck on
the bark of the branches. There's also lots of sticky white substance
associated with them. You haven't mentioned that. You have aphids and
plant lice, hence the curled leaves but also the ants. It's too late
to do anything once the leaves have curled up. I would keep hosing the
aphids out and let the ants do their stuff or introduce predators. Are
your plant in a greenhouse with other plants?. Also the big chunks out
of the leaves look like a catterpilar's doing. It has now flown
away ... )
