Imagine a critter that consumes food wastes quicker than you could dump them, produces fertilizer, and moonlights as a protein-packed snack for cattle. Meet the multitasking high-protein mealworms. Scientifically referred to as Hermetia illucens, these squiggly animals are rewriting waste management and sustainable agriculture. No capes required. Just a ravenous appetite and a talent for converting garbage into riches. Click here for more information!
Good cause drives farmers and environmentalists to buzz about these larvae. Imagine like this: Two pounds of organic garbage can be consumed in a day by one pound of these wriggles. Not finicky eaters, leftover pizza crusts, banana peels, even coffee grounds are leftovers. Most bugs see picnics as side-eyed, but these guys are the composting celebrities. Their nutrient-rich residue, which plants go berserk about, is like the cleanup crew following a crazy party.
But hold on; there is more. These larvae are not merely garbage fighters. They are a master of proteins. With up to 60% protein, they are the preferred food for chickens, fish, even dogs. Consider them animal kingdom’s equivalent of protein bars. Farmers substituting larvae for soy find plumper fish in ponds and shiner coats in animals. “My hens line up like it’s Taco Tuesday,” one poultry farmer said jokingly.
The worst part is that raising them is less work than maintaining a houseplant alive. They do best in warm, humid surroundings; no sophisticated arrangement is needed. Sort them in a bin with some leftovers; they will handle the remainder. They are low-maintenance and do not flee cages unlike mealworms or crickets. They also harvest on their own. They crawl out of their bin, ready for collecting, when mature. They seem to be saying, “We’re done here; thanks for the snacks.”
Sustainable development? Ask. Comparatively to conventional cattle, these larvae require a fraction of the ground and water. Using them produces a pound of protein using 75% less land than beef. Their footprint on carbon? Not that much of a blip. These bugs provide a means of feeding expanding populations without destroying the earth as climate change looms.
Not all rainbows, though. Scaling up is not a stroll-through process. Control of odor can be challenging; consider a gym bag left in the sun. Key are good ventilation and control of moisture. And crowding too many people in one area slows their rhythms even if they are cool housemates. Everything depends on balance.
Ask about do-it-yourself projects. Beginning small is a good approach. Get a plastic bin, drill vents, and toss cooking waste in it. Drop larvae, and see the miracle. You will have compost and fat larvae for feed in weeks. Pro tip: Steer clear of meat and dairy unless you enjoy odd scents.
For these larvae, the future seems brilliant. From biofuels to animal feed, their possibilities go beyond the wish list of a little child. Even looking for cosmetics and medications, researchers are investigating their oils. One expert said, “They’re the Swiss Army knife of insects.”
Think again then next time you toss leftovers into the garbage. One banana peel at a time, those wrigglers may be the secret to better life. Who knew something so little could solve such a large-scale difficulty? Plot turns abound in nature; this one is a page turner.
