Ok, I have like a million and seven little gnat/fruit fly thingies flying around my room, and I haven't bought or cultured a single one yet!!!!! :? My mom is getting pretty irritated with them, and I have no clue where they are coming from! They started showing up when my viv got closer to being done, and I added some sphangium moss and some moss I bought at the West Coast Reptile show from.....someone...lol. I'm assuming they are coming from the sphangium, because when I took the bag out of my room the number of lil bugs decreased, but I have large amounts of the sphangium moss in my frog viv and my firebellied toad viv, and I was wondering.....is there anyway to harvest these guys and use them as a free food source? Is that safe?
