Black Soldier Fly larvae have solved many problems relating to the disposal of food waste products for me. No longer do I have to collect grease in a special disposable sealed container to keep its scent from attracting houseflies or creating a mess in my garbage bin. No longer do I need a kitchen sink garbage disposal to dispose of fruit,vegetable and other waste that would otherwise smell and attract pests. No longer do I ever have to wash out my curbside garbage bin.
I simply pour the grease into and toss
the food scraps into an open bottomed compost bin that sits on the
ground under a shady bush next to my back porch. I dig a one foot depression in the center to catch liquids (the size actually depends on soil permeability). I put down a layer of leaves or grass clippings to begin with. I add my food scraps, etcetera in the center and add more of the plant material. Repeat.
When you first start, I suggest you do
not do so in the cold season. Once established, the soldier flies will
remain established as long as you feed them. In the winter, the larvae
are generally inactive (except on warm days) so the scraps will increase
in depth. But since the weather is cold, there is no odor. Come Spring,
the soldier fly larvae activity booms and the surrounding wildlife
benefits as they eat the escaping larvae as they leave the bin to
[Note: Do not throw raw meat waste in the cold season. In warm weather, they'll devour raw meat quickly before it can smell. ]
you might occasionally overpower their ability to consume what you give
them, it'd be best to place the bin downwind. They'll
target the stinkiest scraps first, so even then the odor would be of
short duration. So, if you're slaughtering more chickens than usual,
take this into account. And note that
houseflies do not like the liquified conditions in the bottom of the
bin. Indeed houseflies are somewhat repelled somehow by the presence of
the larvae bin.
Note: When going on vacation, If you want to
maintain a thriving population, I suggest you lay in a supply of food to
be given to your larvae by whomever takes care of your house. I buy a
big bag of birdseed at PetCo each June when it's on sale for this
purpose. I finish off the bag in the winter by sharing it with the birds
that no longer have soldier flies to eat.
During warm weather,
the larvae leave the fly bin and are mostly picked off by birds in the
day and toads at night. In the fly bin will be lizards that eat larvae
(but they are so prolific that it doesn't matter). Thus the cycle of
life is completed & strengthened by using food scraps in my "lazy
man's compost bin"!
Note: I have two bins. I alternate between the two. The inactive one, I empty and use the very rich compost.
