I’m Leaving You Herbert and I’m Taking the Grubs With Me! (Or Garbage In, Pure Food Out)

Dear George,

I am so excited about an insect that God created I can’t stop talking about it, or them! Imagine a bug that can’t bite or sting you, does not want to invade your home, but only lives to eat every kind of garbage and manure and produces perfect food for poultry, fish, frogs, and many pets!

The adults live only a few days, mate in flight and lay about 500 eggs that hatch into larvae that do the above. But, you may say, “Who wants to harvest garbage or manure-eating larvae?” Yuck! Here comes the neat part, they self harvest!

The mature larvae have the rare ability to climb out of their feeding bins when they are of size. They climb a ramp you provide, to seek a place to pupate. At the top of the ramp they drop off into a container or onto the ground for waiting chickens (say) to eat. There are videos showing hens waiting for them and gobbling them up. The larvae are really nutritious too, high in calcium, good for egg laying birds.

Who are these insects? They are Black Soldier Flies and their grubs are sold under various names, such as Phoenix worms, Soldier Worms or BSFL. Many are raised to feed pet lizards and fish.

Universities are writing them up big time. A friend found them written up under the title “Forging a New Food Chain.” We were thinking of self sustaining food chains and here this came up!

He also showed me the most charming video of a tiny little girl feeding hens from a container of grubs. She said “This will make them very happy.”

Hey, George, it makes me happy too!

About the title, Gary Larson who drew The Far Side, made a cartoon of a female bug preparing to leave her husband who was watching tv. She is carrying their grubs and a suitcase. I miss The Far Side.

    1. That’s the name used for them at Linda’s Gone Buggie, in case anyone wants to purchase some from her company.

  1. I really like the story about the BSF. Just think, if a person was to go live in the woods and survive, they could get some of these BSF and larvae and feed them to chickens, which in turn would lay eggs and also produce meat. Since a person would be in the woods and couldn’t get to a store to buy chicken feed, this is a perfect idea. The BSF larvae would supplement whatever the chickens could scrounge up to eat on their own.

    1. BSF larvae as part of a food chain makes a lot of sense. I’m surprised we haven’t heard about it before.

  2. I e-mailed a number of sellers of repti worms. Linda of Linda’s Gone Buggie was the only person who responded. She has the old-fashioned business ethic and answers you promptly. So I ordered from her and intend to in the future. I like Sarah’s idea of taking BSF to your retreat. Was in the post office last week and a woman was mailing a little box with 6 baby geese in it, chickens, ducks, and geese travel easily when they are babies.
