Black Soldier Fly

The Big question, How do I raise black soldier fly larvae? The following will give you the short list on how to raise the larvae.


Life Cycle



Enclosures-Bins, Buckets



Types of equipment


This is the life cycle of the BSF larvae.

BSF care card

When feeding your grubs make sure you don’t over feed them. Only feed them as much as they will eat in a day. If your using manures then make sure you don’t pile it on as the heat from the manure breaking down can over heat your grubs.


Food BSF grubs like:
Soft fruits such as • melons, • peaches, •plums, etc. Vegetables, • potatoes, • onions,• lettuce. Meats all of them. Manure- “Caution” don’t feed the manure from the animal that you want to feed your larvae too. Example if you feed your larvae to your chickens, then don’t feed the larvae chicken manure.
Foods BSF grubs don’t like
Bones, • pits, • seeds, • eggshells. Hard skins such as • melons, • plums, etc. You will notice the skin is left in your bin after the grubs eat all the soft portions. Most fibrous material such as • artichoke leaves. Carrots are not a favorite either, but in time they will eat it.

Temperatures for black soldier fly larvae
GRUBS like a temperature around 75-85 degree F. Don’t place your grubs in the sunlight or you can overheat them. If you have a lot of grubs then they will provide there own heat, and can heat up there area to 105 or so degree F. If it gets cold outside, you might need to provide an external heater. Your heater should be on a temperature control thermostat to make sure you don’t overheat the area. See below for examples of equipment you might find useful. FLIES like a temperature of about 85-95 degree F if they are going to mate.
