I've put one onto an infested plant to try, it didn't seem too interested

Upon closer inspection, they may be greenfly or aphids (I'm not too well up
on insect identification)
What brought my attention to them in the first place was hundreds of what I
thought were dead ones on the compost underneath the infected leaves....I
think these may be egg casings or similar but the actual insects themselves
don't look white, they have a green tinge to them.

no red spiders, there are one or two minute spiders who have built webs
amongst the plantpots, but I'm leaving these in as they are catching the
flies as they fall off the plant.

I've not tried anything apart from marigolds...where do you get that yellow
sticky stuff from? - what's it called?
