black soldier fly bin
We decided to show you our black solider fly bin and discuss why we have them. For those of you watching our greenhouse build videos, you may have noticed a white rectangular box in one corner of the greenhouse. We will also give you a quick tour of it and show you how it works.
You can see our build post on this bin and get some additional information on the black soldier fly in this older blog entry. We bought our plans for the bin, as well as our starter BSF larvae, from Northwest Redworms.
What we feed the black soldier fly larvae
The black soldier fly larvae will eat just about anything. Any food that you might consider as fast food for human consumption is terrific for black solider fly larvae. We have a brewery near us and they give us the spent grain from the brewing process and we feed that to our chickens and add it to our black soldier fly bin.
In the past we also have fed them a cheap dog food and grain after moistening it first. The dog food was more expensive for us than grain, but there was almost no unconsumed pieces. With grain they will not eat the hull of the grain.
With the feeding of grain you will eventually need to remove the uneaten portions of the grain. It is typically lighter than the contents of the bin and can easily be scooped off the top.
If you do not have a brewery close you could likely get food scraps for free from a restaurant, school or fast food place. With a little bit of your time you should be able to secure a good source of free food for your black soldier fly bin.
A great source of fat and protein for the chickens
Black soldier fly larvae are high in fat and protein, over 30 percent of each. The chickens absolutely love them and come quickly when we start tossing them out to be eaten.
It does take a fair bit of food to grow black solider fly larvae. For every 100 pounds of food added to their bin we expect to harvest around 20 pounds of black solider fly larvae. If we were buying all their food that might not make good sense, but remember we get our spent grain for free. At the end of the summer we will have saved money by reducing our chicken feed bill.
Video of our black solider fly bin
Here is our latest video of the black soldier fly bin we keep out in the greenhouse. You can see how it works and get a quick look at the BSF larvae in action. We find it interesting and our chickens absolutely love them. When we throw out the larvae for them to eat they really get excited.
