The Black Soldier Fly reddit

'The Black Soldier Fly', or, Hermetia illucens is a common and widespread fly of the family Stratiomyidae, whose larvae are common detritivores in compost heaps. Larvae are also sometimes found in association with carrion, and have significant potential for use in forensic entomology.

Black soldier fly larvae (BSFL) may be used in manure management, for house fly control and reduction in manure volume. Mature larvae and prepupae raised in manure management operations may also be used to supplement animal feeds. Larvae are sold as feeders for owners of herptiles and tropical fish, or as composting grubs. They store high levels of calcium for future pupation which is beneficial to herptiles.

Short-tailed Netelia flying around my bin

I am trying to attract black soldier flies, so I set up a failed bokashi bin (stinky, didn’t property ferment) under a shaded area and tonight it’s absolutely swarming with Short-tailed Netelia wasps. They’re harmless to me, and I’ve had them around my worm bins every summer (only appear at dusk) but I want to make sure they’re not going to cause issues with attracting black soldier flies.

Too many mites in bin

So I have a large bsf bin with a huge amount of mites. What can I do to kill them off without harming my larva and flies? I'll try to reduce moisture but most of their food is stuff from our garden... so it's on the wetter side. I'm almost tempted to start this bin over... It's so bad. Please help me.

Optimal density

Hello, I wanted to start my own BSFL bin and I was wondering what is a good depth for the food waste? Like if you pile 500k larvae together in a bin would they still work or nah

Is this BSF?

Something is eating our indigo leaves. And this creature is on the indigo. Is it a BSF? Is it the likely culprit?

Where to order small BSFL

I’m late to getting my bin started this year. I want to order small live larvae instead of doing it naturally which takes too long. I’m in Alabama.

Designing a specific diet for fat accumulation

Hey all,

Any of you might know/ or have experience with free softwares or apllications which helps to build a diet based on specific food ingredients (3-4) and reaching specific nutritional values ​​in the general diet? The goal of the diet will ultimately be to increase the percentage of fat in the larvae so if you also have some recommendations on what waste helps to get the larvae rich in fat (fat percentage in larvae and not total mass kind of fat)

Thanks in advance,

Zach

Mosquito Bits aka BTI aka Bacillus thuringiensis israelensis... Will it hurt BSF?

I have a rotating barrel compost bin and BSF's have once again taken up residence there in force. The barrel is not water proof and it's gotten pretty wet in there and while it doesn't seem to be wet enough to hurt the BSF's, it is breeding mosquitoes. Does anyone know if the Mosquito Bits will hurt the BSF?

The active ingredient in Mosquito Bits is Bacillus thuringiensis israelensis which feed on the mosquito larvae. In truth, I would have thought the BSF would feed on the mosquito larvae but if they do it's not fast enough.

Bakery waste as substrate

What would be the effect of high carb biomass like breadcrumbs, waste bread, and other misc bakery waste be on the larvae?

I'm considering feeding them solely on the mentioned materials as they're particularly abundant in my area, and it seems like the most efficient biomass to spend money transporting; energy per kg- wise.

How big of a difference would it create in the nutrient profile of the larvae, compared to larvae that's been fed a relatively more balanced input?

BSF or Housefly

Please don't judge, my compost has taken a turn.

I've got thousands of these. I really want them to be BSF, but am worried they're houseflies. My green cone composters are usually pretty low-maintenance, and filled with red wrigglers. Last week a bear knocked this one over, and it sat uncovered for a couple of days. When I cleaned it all up, there were flies buzzing around, and I didn't look to see what kind. Now the compost is very wet, and very infested with these larvae.

The thin end is the head. I've googled extensively, and can't find a side by side comparison of the two that leaves me confident but I'm leaning towards Housefly.

Flies are not breeding

Hey guys, I am completely new to raising black soldier fly larvae. I have managed to raise them up to their adult fly stage, but nothing beyond that. The flies have not been visibly mating, and I have not been able to find any eggs/larvae.

How can I get them to breed?

The ambient temperature in their enclosure is roughly 20-28°C. For an attractant I mixes up some old crested gecko diet I had laying around. For the laying idea I put wood pieces stacked on each other separated by cardboard.

Moisture to dry feed ratio

Hello Im breeding BSF's for the first time and started to worry about how much water they should get. For the first generation I'll likely feed the larva animal dry feed but what ratio of feed to water in weight is good for larva growing from hatched egg to adult?

Can I blend the feed and water together to make a slop for them that has the right ratio?

How to stop larvae climbing out

Why would they all be trying to get out? This is my second bin and I've managed to get eggs and lots of larvae, but they seem to be all climbing up the edges, even the little ones. Is this due to too much moisture or os there a way to stop them climbing out? I've got ramps which were collecting the prepupae but this morning they all seem to be climbing up. Thanks

Lighting advice for small love cage

Hi! Really glad I found this subreddit; So, I've been going about raising feeder insects for my pet box turtles, and have been figuring out the best way to do BSF. Thanks to a decent variety of sources, I've acquired the following

Jump Start high output t5 grow light system with timer (have been using it grow a garden and was hoping to be able to use it for the flies as well), currently set to a 12 hour daily timer

and a small love cage (this is only going into feeding 2 box turtles (one of whom is still growing up)), roughly 24" x 24" x 36". Specifically, it's a RestCloud butterfly cage I ordered off amazon, with the growlight and garden right next to the cage (if perpendicular)

I've set up a heatpad underneath the cage, and put a small plastic container (on top of where the heatpad is) in the center, where the larva can have their food and water, and have a trap set above it for the mating

Anything else I should add? I figured I'd need to add more than just the heat pad (I know that heat one of the key components to them mating) to keep it warm in there, but it's the spectrum that I'm most uncertain of. I mean, is the grow light enough, or is there more I should get?

Apologies if the information is insufficient in any way, or I stumble over my words; just ask, and I will do my best to clarify

Any information is much appreciated!

No larvae

I’ve got hundreds of flies trapped in a mosquito net set around each of my bins but I don’t see any new larvae or eggs. They’ve got plenty of cardboard to lay in, rotting fruits and enough substrate. Help?

Crushed acorns in the bin

Has anyone every tried to add crushed acorns to their bin? I've got a whole bunch of acorns that aren't viable as seeds or food and I'm trying to determine if adding them to my BSFL bin would be bad due to the amount of tannins. I know that most, if not all, had been infested with acorn weevil larvae. Thoughts?

Will they eat bones?

Newbie here! From what I understand there isn’t much they won’t eat. I know most chicken scraps are pretty safe but can I give them chicken/beef bones?

Flies in with soldier flies

How can I keep flies out until the soldier fly bin takes off. I have a fair number of soldier fly larvae but it's not enough to discourage flies....I still have a lot of flies in the bin.
