I believe the easiest way to get compost to the bin is via 4 children, but I understand there are drawbacks that come with that particular solution. ;-) We generate an enormous amount of compost. Husband loves cooking. He loves buying vegetables more than he loves to cook them, unfortunately. He is more of a meat guy, but based on his shopping I believe he wishes he ate more vegetables. Between the food we do eat and the food that goes bad before we eat it, it's a pile. Our compost pile has been overflowing for a long time, despite being able to use much of the good product this summer. This fall I bought two of these geobins for composting, and so far am happy. I would think they would make a good temporary bin to keep closer by in winter if somebody didn't want to use a plastic garbage bin. I bought them because I truly didn't have time to build anything myself, and by the time I bought supplies I figured I wouldn't be too far off the $32 cost for the geobin. It is easily adjusted from a small to large radius so I didn't have to think about sizing. Geobin composter I used to "do" composting better. Kept it wet, turned, and hot/warm, etc. Our chickens we used to have were a huge help. Now I don't have the time. I'm into cold composting, which is a nicer way to say "dump it and leave it."

Whatever may have caused your last batch to be "lousy" was unlikely to have been bugs, big or small. Maybe too much water; maybe not enough....maybe too much of one component; maybe not enough.... Unless you're planning to be in a compost-making contest, I really wouldn't worry about your CP. Eventually, you'll have compost! And, unless the experts here correct me, even the "lousy" compost can be used in the garden, to the garden's great benefit. I used to question so much - how many browns did I need, did I need more greens, if so, what kind, were animals getting into the pile and etc etc etc. Now....there are several big piles sitting out there. One never got turned much, and it had FAR too many grass clippings in it. In fact, you could have called it my grass pile. Now? It's beautifully aged compost. Next to it is a smaller, nicely evolving pile that I tended to more conscientiously. It looks...well, suspiciously like the first pile! And next to that is my newest experiment -- I fill paper grocery bags with combos of shredded papers & other "browns" (like floor sweepings etc) and "greens," like the contents of our kitchen compost bucket. When filled, a bag is piled on top of or next to the bags already there in the pile. I stab holes in it and leave it alone....I'm expecting perfectly good compost in time. I don't worry about animals using my piles because it's impossible to do much about it. The fenced-in part of this property is visited by: birds, large and small (including vultures); rabbits; a groundhog; mice; squirrels; feral cats; and, at least once, a coyote. (Hmmm....one of these days, I really must repair the holes in the fence!) No way am I going to sift through my piles and remove any little offerings that may have been left. And I certainly never worry about insects. Do anything about bugs? An absolute impossibility. Besides, insects are an integral part of the great act of decomposition. Or they're not....regardless, I get compost piles...eventually. :)

dsfoxx, it sure is refreshing to read someone posting factual statements about black soldier fly larvae. Have you blogged or posted much about your experiences with them? Since this thread shows up frequently in search results I would like to comment on some of the previous statements. Culturing BSF is my hobby and I'm still learning about them, but I'm familiar with the basics of BSF behavior and life cycle. I don't have much experience with traditional composting so I'm not qualified to give advice about that specifically. My observations are based on working with dedicated BSF "composting" units. From previous comments in this thread: "The BSFL were undisturbed. Temps of 145 -150 did not bother them in the LEAST." BSF larvae die at about 113F (45ºC) "There's a particular barnyard aroma to BSFL piles." The only consistent aroma I've found with BSF colonies is the mild smell of wet straw. The typical smell generated is that of wet straw plus whatever waste you're processing. When I add cinnamon bread to my BSF composter it smells good, like a bakery. If you search you can find several references to the mild odors associated with BSF larvae. Foul odors are sign that the colony is out of balance which is usually simple to fix. In a properly managed dedicated BSF unit anaerobic bacteria are limited by the constant churning of the larvae which aerates the waste. A well designed BSF unit will have good drainage to avoid flooding. "I put a fly swatter out there this summer, and I kill any adult I see, on the 'no egg, no larva' plan." You'll only be wasting your time and burning a few calories with that approach. "I'm thinking about starting off next year with a garbage can--sounds grim, but at least then the mature larvae can't crawl off to pupate. If they 'all' lay 'all' the eggs in a solid plastic garbage can, I can put said can in my truck and take the whole business two hours away to my mother's farm--Mom has chickens, and Mom is tough. Mom once shook Japanese beetles off her fruit trees onto a sheet and saved a five gallon bucket of them in her freezer to feed her pet chickens over winter." Your Mom sounds cool. However, it's possible for the larvae to escape a plastic garbage can under some circumstances. They can climb a smooth vertical surface if there is condensation present, and they can squeeze under any lid that isn't extremely tight fitting. Also there is little chance that "all" the BSF would lay on the garbage can anyway. "Black Soldier Fly larva are used to consume animal manures and the only thing the adult flies do in their about 30 day life is look for another BSF to mate with,..." BSF consume most food waste in addition to manure, and their lifespan is reportedly 5-8 days. You're right about their goal as adult flies. "...so except as a food source of predatory insects or birds they really serve no purpose." BSF larvae actually serve as a food source for an extremely wide variety of animals including birds, mammals, insects, reptiles and amphibians. But the idea that such a powerful detritivore serves no purpose other than as prey for other animals isn't logical. "I have noticed often when these larva are present there is a putrid odor to the compost indicating too much moisture which displaces the necesary air which creates that putrid odor." I agree with your statement because you qualified by saying "often". The point I want to stress is that putrid odors are not necessarily a part of BSF culturing and can be avoided with an understanding of their life cycle and behavior. "I definitly did not use enough brown, realizing that now, but i also remember that i saw the little buggers in the yard in a pile of yard clippings in a bin before i even started composting so they were here already somehow." Anything's possible but it would be unusual to find BSF larva in a pile of just yard clippings since they don't normally consume such high cellulose items. You're probably right that BSF where already there; they are very common in most of the United States and around the world in hot to mild climates. "I offered the maggots to a local chicken farmer but she was concerned about introducing them around her house," The farmer's concerns were unfounded; if you had BSF then she would have had them also, especially with chickens present. The interesting thing about BSF is that they normally do their important work virtually unnoticed by people because the adults don't pester us. Typically a female BSF will lay eggs near a food source and then leave to finish out her short life without ever coming into contact with a human. Furthermore if your local farmer understood that BSF larvae limit reproduction of house flies and other pest species she would welcome their presence. "I can't imagine having a compost goal of never having any soldier fly larvae, ever. It would be too much like looking at composting as requiring a recipe and a perfect rate of completion and outcome, like baking perfect bread that either comes out "right" or is tossed out if it goes a bit one way or the other. I mean, one piece of pumpkin or apple in a bit cooler area of a pile may harbor some larvae." What a reasonable person you are. "I find that it only takes a day to get it heated up and cooking. Weekly turning will keep it cooking, and I don't usually see them in the core. They might stick around on top if I don't have enough browns to cover it with. BSFL are just a normal part of composting if they live in your region." And another balanced perspective! "I put in kitchen scraps and hay and some paper. Things went well, though during the cooler months it wasn't breaking down much. Then about a month or so ago we noticed that all the gnats were gone, the stuff was starting to break down, and the bin was full of what seemed to be Black Soldier Fly maggots. The smell was fine, and I read up on it and thought it was ok, so I let it go." This is what I would expect in a properly draining system inhabited by BSF larvae. The reduction of gnats (and other flies), rapid breakdown of waste and mild odor are all typical of a balanced BSF unit. "The Aerobin has a tea spout at the bottom along with a bottom drainage system. A couple weeks ago I noticed that the bottom of the Aerobin was seeping sludge. The tea spout produced a lot of liquid, but didn't stop the seeping sludge. I opened the side doors and it was just disgusting. Maggots fell out, sludge fell out, and it smelled like sewage." And this is what to expect when there are BSF present but there is inadequate drainage. As someone mentioned above; standing liquids create a zone where anaerobic bacteria can thrive creating the sewer-like odor. I realize that your Aerobin isn't designed for BSF composting, and that in the absence of BSF it's drain system would probably work fine. Without the BSF your waste would break down much more slowly giving the moisture contained in the waste time to evaporate gradually. When BSF larvae quickly devour high moisture waste like fruits and vegetables all of the liquids are released, overwhelming the drain. One possible solution to your problem might be to line the bottom of the unit with a filter material to keep the drain open. Coconut husk fiber (coir) works well for this and is readily available as welcome mats and wire planter liners. If you had been able to regularly drain the excess liquids I don't think you would have seen the smelly sludge develop. As mentioned above; it's not likely you'll be able to keep BSF out of your unit. I wouldn't put hay in the unit again due to the clogging your husband noticed when he cleaned the unit, however you might have better results by adding wood shavings. Wood shavings help absorb excess liquids but don't tend to clog as much. A lining of coir with a few inches of shavings might result in very low maintenance and high volume waste processing. I often add wood shavings or sawdust to my BSF units if they become too wet. "On the news tonight they mentioned that Florida is having some sort of infestation of a biting yellow fly, so that didn't make us feel any better." What does that have to do with BSF which are neither yellow nor biting? In fact, depending on the breeding habits of the yellow pest flies, having BSF present in your waste may actually deter them. BSF are proven to reduce house fly development in waste 94-100%. - "The black soldier fly (BSF) is a southern native, non-pest fly that unlike the house fly, is not attracted to human habitation or foods (Furman et al. 1959). BSF reduce manure accumulations 42-56% and give 94-100% house fly control through larval competition and by repelling ovipositing house flies (Bradley and Sheppard 1984). Elimination of lesser mealworm has been noted, but not well documented. The digested residue is a friable compost-like material with about 24% less nitrogen (net loss of 60%). From Bradley and Sheppard 1984 (6), cited in Roeder Meyer (8) "The 'putrid' smell people describe when they have alot of BSFL is NOT mismanagement of their compost piles. It's the maggot crap. It tends to be wet no matter what you do." BSF crap does not smell other than the mild odor of wet straw I mentioned above. Again, the BSF don't manufacture liquids, they release the moisture contained in food waste. "Getting a liquid from any compost, except vermicompost, means the material is too wet. The presence of Black Soldier Fly larva means the mixture is too wet." I would frame it that the sudden release of liquids due to breakdown by BSF may cause issues for composting. BSF larvae do require a moist environment, but they are not attracted to either anaerobic nor flooded conditions. - "Hoy (pers comm) suggests that adults avoid oviposition sites that are anaerobic." (1)"Wet substrates were less attractive to ovipositing Hermetia Illucens (aka black soldier fly) (Booth and Sheppard 1984). Therefore, water was added to medium used for an oviposition attractant to near the saturation point to encourage oviposition [in another location]." (10) "Based on observations made at Caboolture Sewage Treatment Plant, soldier flies do not lay their eggs in sewage sludge pilesÂ. Under experimental conditions indoors (described below), adults did not lay in open containers of sewage sludge." (3)" "Since the adult BSF does nothing except mate to produce more larva, and may be among those flies that are known to spread disease pathogens around, there is no good reason to be thrilled about having these critters in your compost." 1.) It's an odd oversimplification to say that any creature only exits to reproduce. 2.) Research indicates that BSF are not vectors of human disease. BSF adults rarely contact waste directly and instead lay their eggs above or beside waste. Since the adults don't eat they don't land on food to be consumed by humans. House flies and other pest species do land directly on waste and then they target human food which is why they ARE vectors of human disease. In fact, BSF have been shown to reduce some pathogens in waste. - "Erickson, M.C., M. Islam, C. Sheppard, J. Liao, and M.P. Doyle. 2004. Reduction of Escherichia coli O157:H7 and Salmonella enterica serovar Enteritidis in chicken manure by larvae of the black soldier fly. J. Food Protection. 67:685-690. 3.) Generalizing that "there is no good reason to be thrilled about having" BSF larvae in your compost doesn't take into consideration the growing number of people who are indeed thrilled about working with BSF. It usually starts with understanding the creature correctly. "If the material is too wet and we know that the liquid is largely coming from the maggots, is the liquid bad to use? I am worried that I just sprayed nothing but bugs on my beans and totally destroyed them." Some claim that the liquid effluent released by BSF metabolism can be used as a fertilizer. I haven't tested this but I don't promote the use of the liquid. I doubt it is what killed your beans though. To all; I hope I didn't come across as too defensive in my efforts to correct what I perceive to be misinformation about BSF. I could be wrong about some of my positions and I'm willing to examine them. I spend so much of my time undoing misconceptions about BSF that it gets tiring. I look forward to the day when more time is spent helping people design systems and maximize performance. I didn't post reference links but there is a great compilation of BSF data at BioSystemsBlog.com: biosystemsblog.com/2008/07/09/black-soldier-fly-compiled-research-on-best-cultivation-practices

If you are worried about critters, avoid composting the normal compost "no-nos" like meat, dairy, grease, etc to start. Once you gain confidence in composting and know what your pile is likely to do, you will learn what you feel comfortable composting. It might be a good idea to get a compost THERMOMETER so you can see how the pile reacts to different additions and conditions. I have found that if you put the "no-nos" in the hot middle of the pile, that critters have not been interested. My pile gets very hot though 150 degrees F in the hot part regularly. Here are some links about composting that (even if you don't compost what the title encourages) will give you a good idea about what composting requires. http://www.jenkinspublishing.com/humanure.html http://www.weblife.org/humanure/default.html Before reading that book I had some smelly, not so good attempts at composting but after reading the book, I've been able to compost anything I want. We take out trash only one or two times a month and it never stinks or overflows the can. Here is a link that might be useful: Composting
