little red bugs... couple questions

Thoes little red bugs... i see and smush about four a day in my veg room.... but one time a lil red guy came out from in the dirt running up the stem of my haze and it worried me.. they are outside and around but im not sure how they got in. a fair share little tiny black flies (but dont seem to be gnats) started appearing as well. I was planning to put neem oil on all my plants... (13 veg and 1 flowering) and maybe even water the soil with it to kill any eggs... any sugjestions

and this whole online forum is the coolest thing ever.. i have so many questions this is gonna be great.. thanks to whoever reads or replys

So i am pretty sure that they are red spidermites... they are fast as hell and i can barely see them but i am becoming a red bug spotting monster... i find them mostly in the drain dishes and the top soil... still worryin but its nice to finally beable to put a name to the bug.... i also sprayed the hell out of the 15 or so guys in the veg box with a light neem oil and soap spray...
