m0useanswered grow question 6 months ago Its hard to focus on them as the pic is bury and does not show the subject in detail but they do not look like springtails from the shape they are displaying. They look a lot like they are teardrop shaped and that is similar to aphids and mites. Not say they are that but that's the common body structure they share. some soil mites are not invasive or a pest.
Like Mrs.Larimar said Neem has its usage and I think its better topically vs as a soil drench. You could try using some BTi or Nematodes, they are opportunistic killers of some soil dwelling bugs, mostly Gnats and thrips but can also work on a few other pests and I have treated springtails before with them. It would be best to identify the pest first though. HD images of them and note any markings or colours. very basic, 6 legs insect/bug, 8 legs mite. different kill methods for taking care of that after identification.
If you plants are looking healthy then its nothing to sweat. If they looking sickly its time to nuke em.
Good Luck!
