Hi Gabiche, I have the exact same problem you describe in your May 3, 2016 post - small greyish bugs (some really tiny yellowish ones ) of varying sizes in the saucer of my schefflera houseplant. I took a picture that looks exactly like the ones you posted. They don't jump or fly and i don't think i see anything on the plant itself. Although a bunch of the leaves look pretty sickly. Did you ever figure out what they were or what to do about them? They keep coming out of the bottom of the pot and keep finding them on the saucer.
