how to you know their bugs? I have the worst eyes for them. please advise how you located and knew what to do.

how small are they? I asked cause I wonder if I could have same issue with another plant. I see black things on my plants but I don't see movement?

They're very small, they like damp places so they were in the soil and at the edges of the pot.

I have a new bonsai. just got it for a mother's day gift. do you know if these things are prone to be on other household plants. I have a large variety of plants from succulents to Pothos and Ivy's. Then jade, umbrella tree, Bromeliads, cactus, pink dot or freckle face it's called. A bamboo, some herbs and air plants. I mention all of this because, I have had issues with plants dying and I have no idea after reading and posting why they're fading.

These bugs shouldn't be harmful to the plants, they're found almost everywhere soil is

well I found the same microscopic bugs on my bonsai today so thank you for looking into it. not if I can just leave combat a fungus issue or blight they call it?

For bugs confined to soil, simply soak plant in water for about 1.5 hrs. This will also destroy the membranes on any eggs.

If you suspect bugs on leaves ( many do not move ) start spraying asap. Dont try to mix your own horticulture spray unless you have those skills.

spray what? I have a 3n1 mutliuse for fugus, mildew issues and pest problem. I have spray my larger dracaena plant and other house tropical plants.

also how do you soak plant in water without losing all the soil?

Proper bonsai soil will not float away. Most of mine are in Turface, which doesn't float but some have chopped bark mixed in. The bits that float can just be put back in. If yours are planted in regular soil (dirt) you should consider repotting in a more coarse mix. You could also place (pea) gravel on top to keep the soil in place, and remove it after treatment, or leave it as a decorative feature. Most of mine are already covered with moss so nothing falls or floats out.
