Nope they never fly! these bugs look more like a termite but so small you can barely see them,perhaps they are a good bug for the soil? they don't fly but crawl fairly fast for their size I did a search for pictures of soil pest but only came across avaible pictures of some bugs,and the pics that I did see looked nothing like the bugs I have......

Like I said they don't fly,brownish in color,even smaller then spidermites,even smaller then all the bugs I seen pics of.....

they hang around the spilled out soil that comes out of the drainage holes! they may have little antana's as well! but these bugs are small dude!
