I just call whatever loves my moist T soil " dirt flys" . Typically I will let things dry a bit and yes put in the springtails and Iso's . Yes, the maggots are in the soil! The springtails will out compete the maggots for food and bit drier helps. Hate these things! Dave of Dave's little Beasties calls them Phorid flys! His , I think, Omythymus Violaceopes got covered and he pinned and would brush the maggots and flies off her! That Dave is the man and definitely loves his spiders! Big OW spider to deal with like that! And yes I have fly paper as well! It has become a must have..lol!
