Black Soldier Fly - Beneficial Bugs

20111011-233759.jpgI just love these little flies! There are around 120,000 different species of flies around the world but this one seems it can really be a benefit to the gardener/farmer because of it's eating habits and they can be fed to your chickens! At times it can be hard to remember flies are a benefit to the whole world because they buzz around your face, eyes, and seem to want to fly right in your mouth to choke you to death! 

I myself like to watch to see if a bug I find in my garden is a pest or a benefit because I can use beneficial bugs to help me in the garden. Some flies can aid in controlling other insect pests (hover fly larva kill aphids). Flies also are good pollinators! Only bees and a few wasp pollinate more plants than flies.

I first found these flies breeding in my compost and just had to look them up to see what they were. They do not bite because they have no mouth parts which also means they cannot eat. Very short life for these flies! You may even say "it's the hard knock life for them";) LoL!! 

If you have lots of these in your trash or compost then you will have almost no houseflies around since houseflies hate black soldier flies. Houseflies are the flies that you hate, not these. 

These flies are great for breaking down waste! The adults look like mud wasp but I can assure you these are flies.

They eat many kinds of decomposing organic matter, including algae, carrion, compost heaps, manures (rabbit and chicken), mold, plant refuse, and the waste products of beehives like it's candy! They not only eat all that but they also eat meats! That can come in handy if your trying to get rid of bodies! LoL!! Just kidding:)

"This non-pest larvae converts the manure's nutrients into 42% protein and 35% fat feedstuff. This conversion of waste into feedstuff is called bioconversion and, consequently, the larvae can be fed right back to the animals or birds that generated the waste or used as feed for fish or livestock. It can be ground up and fed to earthworms or red worms for a second round or just used as compost. The larva is dry and odorless."

You can also set them up to self harvest for chicken, fish, frags, etc etc feed. Hope this helps you guys keep these flies around your yard as they are a great benefit!!

God Bless:)


  1. Hello! Are these larvae available for sale? It would be nice to get them introduced to a new compost pile i am starting. Thanks! (They will probably find it eventually if in the area, right?)

    1. I don't know that you can buy them anywhere:( If you build it, they will come is sort of the idea:) I like to mix a bit of rotting veggies with a little water to get it smelling really "good". Where do you live?

  2. Matt,

    Matthew Thornton from Memphis here. I was watching your Youtube video about BSF harvesting. I'm new to all this and I will check your videos and blogs. Thanks for posting.

    I noticed your corn planting pattern. Corn pollinates by wind. You'll have a healthier corn crop if you plant in a square plot instead of two long rows.

  3. Thank you on the tips for growing corn!! I don't grow tons of it so what I'm doing works okay for me but if I ever want to increase I'll definitely planet in a square like you say:)
