They look like springtails. they are very small. Not really considered pests as much as a nuisance. But in large numbers they can hurt the health of the plant by working on fine root hairs in potting soil. they can be an issue in hydro. They eat fungus, and organic matter. Do they jump or spring?
Humidity and moisture is their attractant and friend. If you can dry the soil surface daily its a big help. So is air flow. they will congregate where there is the most moisture and can come indoors from outside when things dry up in the summer............
Sanitation and attention to moisture is a big deterrent and control.. most any non-toxic pesticide like insecticidal soap, diatomaceous earth or silica gel will work. I believe they are fairly easy to control by minimizing moisture . If they are outside and coming in, you can put a perimeter around the base of your home with diatomaceous earth or a pyrethrin type insecticide.
