Definitely not ants:- maybe Fungus gnats?It's pretty hard to tell from these pictures.
I'm putting my money on gnats. Soil too wet or something rotting is in the viscinity.Okay, I found more of the little flying insects today. Here are better photos:

Centipedes are predators, eat insects and small children.
There are some long-legged varieties out here (I’ve heard different ones referred to as both centi-AND-milli-pedes)... the bluish-grey ones (Long legs) are docile.. they won’t bite.. the black more shiny ones (medium legs) WILL bite.. like a bee sting(ish)... the classic red/maroon ones (small medium legs) will bite like a wasp/hornet and leave a VERY uncomfortable “burny” rash.. but there are ALSO... HUGE red and YELLOW ones with LONG THICK legs.. and when THEY bite..it is NOT ONLY the sting and the rash.. but nausea/dizziness for a day(ish)..Centipedes, especially large ones, can put a nip on you, they have a venom, usually not too serious, effects are similar to wasp sting.
But centipedes bite, they do not have a tail "stinger". Their venom is in the pair of fangs, actually modified "mouth legs".
