Bud's home made bug-remedy?

[The Mutant]

Can someone please give me the recipe? It's water, soap (?), cinnamon...anything else? And in what quantities?

I have discovered some nasty, minimal, pests on my P. schilleriana when I watered it today. They are seriously miniscule and kind of greyish, with rather round bodies. I've never seen anything like them, but I'll try to find out what they are. For now I need to get rid of the ones on the P. schill (it was put in immediate isolation the second I noticed these buggers). So far I haven't discovered any on my other plants, but I won't know for sure until I drench them I think, they did NOT like the water, but I noticed they hopped on the surface on the water after I had dipped the P. schill in it - disgusting! I got rid of that water faster than you can say "PEST!" and checked the other plants I watered together with the P. schill (none was dipped after the P. schill so none shared the water with it, fortunately) and so far no signs of these pests.

Can you please help me? I'll give the schill a thorough wash with soap and water, and then spray it with pesticide. I would really like to use Bud's remedy though, since it won't harm the plants so I can spray ALL of them. Just as a precaution.
