You or someone you know eats food ;-) and makes food waste. GrubCones™ get rid of food waste. Just Google "food waste problem" and read away. Patent pending GrubCones™ probably won't save the world, but you could do your part to make a dent. And if you keep chickens, feed them fresh grubs too.
Please read Product Details section carefully and all tabs. There are limitations to the successful use of a GrubCone™. We guarantee the product, not your success. Magic is not easy :-)
BSF = Black Soldier Fly (Hermetia ilucens) BSFL = Black Soldier Fly Larvae
The average American family of four throws away about 1600 pounds of food scraps annually. That’s a real problem for municipal trash services.
The patent pending GrubCone™ deals with food waste and as a by-product, produces a premium livestock feed… BSFL aka grubs! The cone shaped design allows the grubs to efficiently “Self Harvest” into a dish at the base of the unit… no touching. That’s good.
The grubs can be fed to chickens at a rate of about 75% Scratch Feed (much lower cost than Layer Feed) and 25% grubs… by weight. The grubs are a super-feed… 40% protein and high in fat. They must be supplemented by scratch feed (or other carb source) for laying hens to get the balanced nutrition required to maximize laying performance.
One GrubCone™ can provide feed intensification for 6-10 chickens and decomposes 2½ to 5 lbs of food scraps per day when operating in target environmental conditions. This will lower feed costs by 75% or more… and save the world.
The magic is you take food waste that was mostly carbs and would have been thrown away and convert it into high protein, high fat livestock feed or just have 2½ to 5 lbs of food scraps disappear into thin air. That’s pretty much magic.
A wasp with no mouth… right.
Sort of a cut-n-dry explanation…
Place GrubeCone™ in a shaded but dry outdoor area. Like under a carport or something like that. Out of direct sunlight. If in an enclosed area, leave a window(s) open.
Load up cone with organic waste. Easiest explanation is food scraps. Peelings, leftovers, spent coffee, rotted fridge food, breads etc. Rotted fruit is gold. You could use feces and carcases (beleive me)… but that’s nasty and a whole other story 😉 Not paper products.
Occuring right where you live (subject to Geographic Limitations tab) are boy and girl adult soldier flies which in the 10 day period of their adult life live for one reason only… to mate (while flying in the air by the way). They don’t eat or bite because they have no mouth. Really.
During the last days of her life, the girl Black Soldier Fly looks for an awesome place to lay her roughly 1000 eggs. Our GrubeCone™ is designed to be an awesome place. She lays her eggs and before long, her and her mate die. Romeo and Juliet got nothing on a Black Soldier Fly.
During the time that your BSFL colony is becoming “established” nuisance flies (that do have mouths) will no doubt also find the rotten food stash. No worries, once established, the BSFL win out and eat the house flies. Seriously. For about 2-3 weeks its gross. But once established, it really does not stink and there are very few house flies. Amazingly so. You have to experience to believe it.
The food waste disappears because the growing larvae are very, very hungry and there are thousands of them growing inside the cone. While the colony is being established, reduce the food scraps introduced. But once its established, pour in as much as the cone will hold each day.
Mature larvae start thinking about sex… (see item 3 above) things start getting too hot inside the GrubeCone™ and they start looking for a way out. Hmmm. If they dig down to escape, they fall through holes in the floor and fall into the catchment pan. If they crawl up the walls to escape, they fall between the dual layers… and into the catchment pan. Pretty clever.
Feed the grubs from the pan to chickens, a pig, fish, ducks, geese etc… or sprinkle them out on the ground and let local birds eat them… or they just mature into adult mouthless Black Soldier Flies and the whole thing repeats itself.
But in the meantime… once the colony is established, each GrubeCone™ will magically make disappear up to 5 lbs of food waste a day… actually pretty easily.
When the season is over, the material left in the GrubeCone™ (pure organic waste and larvae castings) can be used in gardens or just sprinkled on the ground. It’s super rich and just smells like rich soil. We live outside Austin Texas, and in a season, I can put hundreds of pounds of scraps through a GrubeCone™ and only empty it once winter comes.
There you go. Make no mistake, there is skill and experience involved… but read all you want of scientific journals. That’s pretty much how it all goes down.
Where you live matters… a lot.

Understanding This Information More
BSFL grubs themselves are actually pretty resilient and don’t fully die off unless they freeze to death. Composting material gives off quite a bit of heat and the GrubeCone™ itself is dual walled. So can you actually find live grubs in the cone for a pretty long time throughout the year.
But cooler temperatures significantly slow activity, and therefore the grubs digestion of the waste, making the unit not as productive. A unit will stay fully productive as long as daytime temps get to 75°F. Temperatures for mating adults cannot drop much below 70°F at night and they are most active more in like the 80°F to 95°F daytime temps. Since its the mating that produces the eggs and the eggs that produce the larvae… there will be a reduction in new eggs being deposited in the cone except for in much warmer times of the year… basically reducing grub production from lack of new eggs being introduced.
In Haiti for instance, or extreme south Florida, its entirely possible for the units to run fully efficient 12 months of the year. As you go north, the yield expectations drop quickly and in fact will be zero in inland northern states or the furthest northeast states.
Key features of the GrubCone™.
The GrubeCone™ is no accident. Out of a passion to serve the people of Haiti we decided to start placing our chicken coops at schools in Canaan, outside of Port-au-Prince. A sustainable method to feed the chickens was required, en voilà… GrubeCones™. Two years of development and testing culminated in a patent pending design that is functional and interesting to look at. Shipping is normally a killer on these sorts of devices, so it was made to flat pack and be assembled as a DIY kit by the purchaser.

Bargain brand coops are not a bargain for long. Our coops are more durable, which means they last. But it also means they’re predator safe places for chickens to live. Our coops are methodically thought out and have deliberate advantages that save you time and make a healthier place to keep chickens. They’re among the best coops money can buy. We hope you decide they’re right for you…but call us if you have questions. Our #1 goal is to make sure our coops are a good fit for your needs and meet your expectations. Here are 10 things to know about Round-Top Coops™.
Wood - US Western Red Cedar
Cedar will last outdoors many, many years painted or not. It's not chemically treated yet naturally resists rot and bugs. It's very strong.
Hardware - Exterior Grade Galvanized
Heavy gauge exterior grade hardware is much more predator proof and will last a ling time.
Wire - Welded Galvanized Livestock
It's at least 4X stronger than hardware cloth found on most every other coop.
Joinery - Old School Carpentry
Beautiful, strong, outdoor-proof methods will hold up over time and we guarantee it.
Roof - Galvalume™ 5V Crimp
Patented Galvalume™ won't rust, reflects radiant heat, stays cool. Nothing is stronger than metal.
Designs – Beautiful & Practical
We lean towards highly ventilated, roomy, minimal opening designs with weatherproof roosts and open sunny runs. Sunlight is a disinfectant and stimulates egg production too.
Winters – Multi-Climate Versatility
Only use when needed. Magnetically attach Storm Panels in freezing winds and snow. Translucent, lets sun in. Healthy
Support – Chickens Are Our Passion
We’re basically chicken keeping consultants to our customers. We provide unlimited help. We use our coops every single day.
Waterers - Integrated No-Poop
Convenient, overhead no poop, outside fill, can be freeze-proofed, food grade, hold a lot, can add extras taks up no run space. Saves time.
Feeders – Integrated No-Poop
Convenient, vertical no poop, outside fill, weather resistant, food grade, hold a lot, takes up minimal run space. Saves time.
If our coops are in your budget, they’re actually a great value. We don’t try to fool you with “free shipping” that we both know isn’t free. Well made coops are very heavy, shipping them is not cheap. We don’t try to trick you about where they’re made, size or capacities of our coops. We respect your intelligence.
