I started a 32gal trash can style Black Soldier Fly composter a couple of days ago. Some critters have come to visit (stay?) ants. solved the entrance of new ants by raising the bin onto blocks inside a water basin. no new ants, anyway. garden snake. came in with some leaf mold, and fall leaves. he played dead when i saw him, so, i left him for composting....surprise. not dead. housefly maggots were the first colony. they fell out of the air holes below the bin, and drowned in the water bath....i think they have stopped visiting, as i have no new maggots. (the drowned critters fed my aquaponics goldfish) today, i found a small gray lizard (i think they are called "Swifts" here in Texas)....it did not want to let me help it out of the bin, but ran and hid.....i did not want to sort thru 20" of composting materials at various stages of aging, so i let him be for now. i do see the beginnings of soldier fly larvae, in small numbers. my question: will the lizard and the garden snake prove to be predators to my BSF larvae, or should i just let them be?
