Thousands of Grubs in Compost ( picture and video )

Ok, since this is the 'net, it's hard to express oneself fully. The reader cannot sense body language and tones. I started out by stating an opinion that they are small. In many opinions 18mm at maturity is a rather small creature. The birds can pick them out no problem, and it's a great feeder for them, however if you are feeding them to another creature and do not want them eating chunks of compost while trying to get at them, then they are quite small to be picking out. I suppose that if I had read all the pages, I'd have known that you were on, and I would have keep silent. BSFs are your thing, and that's cool. It was just a comment and was in no way addressed to you, and I'm sorry if you thought it was an opinion in regards to anything you had previously written. I was addressing the topic poster.

However, now that it's been opened up, I'd loooooooveeeee a colony of BSFs.

For my purposes, though, having a colony does not fit my environment and environmental needs. I chose roaches (and specifically these 2 breeds) after months of researching them for specific reasons. They don't climb plastic or glass, they don't fly, and they breed like mad. BSFs may breed like mad, but I don't want them escaping and swarming inside my house. I keep the colony in a 1x1' plastic container under my lizard tank in my house and can feel safe that barring any accident, they stay right where they're supposed to be. That is why I don't have any other feeder colonies. If there was a set up that assured me of practically no escapees and maximum control of the environment (no contamination of other insects and no parasitic concerns which, is a common way reptiles get internal parasites), all in a small space that I can keep hidden when guests come over, then I would most definitely start my own BSF colony.

Furthermore, though I prefer soft bodied prey, chitin (the shell) in some quantities is helpful to an adult beardies diet. Adult beardies need less protein than younger beardies and little fat (unless they are malnourished or laying eggs). Roaches have more meat to chitin compared to mealies and crickets and such. Also, I personally have had crickets escape and have seen mealies chew through plastic containers. All things considered, I'd rather have roaches to any other shelled feeder, and (larger) BSF to any soft bodied feeder for my reptiles. When I get my order of Phoenix's in for my boys I'll have to remember to put some in to colonize the compost for my flock (I hope they get here soon!

In any case, I have to apologize to the topic author. This topic is not about the nutritional values of either BSF or roaches and which is better for a reptile. It's about a person's really cool (or some may think disturbing, LOL) find of a huge colony. All I wanted to say was how cool it was, and it is, and you're lucky to have such a find for your flock who will benefit from the high calcium levels.

And, like I said, since one cannot read a feeling or intent... :aww Not a big deal! I really am pro-BSF!

That's cool selena, I didn't take your comments personally. We who raise critters that most people find repulsive (I'm looking at you olp_63) need to stick together.

Now, as a person who has embraced black soldier flies, please allow me to clarify a few points...

BSF larvae are pretty much always raised outdoors. A colony is dependent on regular reseeding by adult female BSF.

BSF larvae are very easy to contain. They are unable to crawl up a vertical surface of any kind with one exception, if the surface is wet. If you store the larvae in something with a vertical lip of 3/4 inches or more then can't escape unless there is condensation present. Indoors you won't get condensation and if you add sawdust or something similar to an outdoor container the larvae are extremely unlikely to escape. It's not an issue outdoors anyway because you want a few to reach adulthood to continue the cycle.

Black soldier flies are not associated with disease causing pathogens. No animal on the planet can claim to be sterile, but after much research there is no evidence that BSF transmit disease. There are studies that indicate that BSF larvae actually reduce pathogens like E. coli and salmonella.

Bacteriological interactions associated with manure digestion by maggots are favorable. Maggots are competitors with bacteria for nutrients and often reduce bacterial numbers greatly, or eliminated them altogether (Beard and Sands, 1973; Sherman, 2000). Maggots may consume and digest microorganisms, and produce antibacterial and/or fungicidal compounds (Landi, 1960; Hoffmann and Hetru, 1992; Levashina et al., 1995 and Landon et al., 1997). As maggots reduce pathogens in manure they may make it safer for organic vegetable production.

From the same article:

Flies that have been used experimentally to process manure include house flies (Musca domestica), face flies (Musca autumnalis), blow flies (usually Sarcophaga sp.) and the black soldier fly (Hermetia illucens). Except for the black soldier fly (Furman et al. 1959), all of these are considered pests as adults due to their disease vector potential, behavior and preferred habitats.

Preliminary studies with black soldier fly larvae indicated a reduction of pathogens in an artificial medium or manure innoculated with larvae. Numerous studies using dried, rendered and fresh maggots as animal feed have revealed no health problems resulting from this practice. Preliminary bacterial culturing of self-collected soldier fly prepupae from a recent swine trial revealed no pathogens

Selena I'm not challenging you about BSF or your choice of herp food, I'm just trying to keep the record straight about BSF technology. Of course I don't know you, but I have to believe that I would like anyone who raises roaches. I tip my hat to you.

(no offence bsflarva- I'm sure they can be quite endearing *shudder* I'm grossed out by the mealworms I occasionally feed my leopard gecko Salvatore, that's why I feed crickets. Sorry, off topic!

I could hear ducks and chickens in the background. Ho boy.

bsflarva,

It looks like I've lost activity in my compost bin with the horse manure. I don't think all the good eatin' for the larvae is spent / used up. I checked last week and had larvae at lots of different stages in the cycle (brand new to dark brown). The pile of stuff is still moist (like wrung out sponge).

Fortunately I've still got some BSFL's working in another bin where I have food scraps, but I sure would like them to keep working on the horse manure pile.
 
Nifty; do you think they are going trough a stage or losing ground?
I want to try this also, you have a good start, I would love to learn.
Just think when you fail, we all learn! I hope that helps!

I just reread that don't take that wrong please!

Nifty, I haven't read much about BSF larvae in compost piles. I know that it's common for them to show up in compost but it may not be a consistently good medium. One problem could be the heat. If the environment reaches higher than 100 degrees the larvae will probably migrate out of the pile.

Envirogirl11, I don't take it personally if you're grossed out by fly larvae. House flies are associated with 277 disease producing organisms so the bias against flies is rooted in some truth. I felt as you did until I started learning about and working with this amazing insects. For the record BSF are not associated with disease transmission.

You might find these two posts interesting.

One thing I've learned from helping manage this community is to not take things the wrong way, so no worries!

I'm not sure if it is stage or loosing ground. I have 3 main piles now:

1) Mostly composted chicken manure, pine shavings, and kitchen scraps. A "cold" pile that is home to a ton of redworms

2) The pile that I posted a while ago which was when I first had the 3/4 pile of horse manure with shavings that I added to an existing pile of kitchen scraps (which I believe already had the baby larvae in it). This is the pile where there is no activity.

3) A new pile that started out 100% horse manure and shavings but 7 days ago (before vacation) I added a bunch of kitchen scraps. Lots of activity in this pile yesterday with larvae of all ages. Today I only see very inactive large larvae so I'm wondering if they came over from pile #2 for a better feast?

I'm learning as I go, so I look forward to any thoughts / suggestions.
