these little things are eating dead material in your soil, so normally no problem for your plant
its more a sign of an organic soil.
if you want to get rid of them because you think they are annoying
tanke the pot and let it dive into a bigger pot of water and let them soak, bugs will swim on the surface of water
i have that from time to time if i take used soil that was resting in my garden to get reused.
live and let live is my motto here. but its your decision
and p.s , using of neem has its limits too.
before it gets poisonous
