What are your composting grubs?

Composting grubs are black soldier fly larvae.  They are a popular feeder insect for reptile owners.  But composting is one magical power these creatures possess.  Many gardeners and conservation enthusiasts love adding them to their composting piles.  What makes them so great they have no limits on what they can consume.  Traditional composting worms (like red worms), can't break down meats, dairy, or citrus products, which is a huge part of people's diets.  So with these composting grubs, you can now compost without discrimination and add any meat, dairy, or citrus product.

How do we ship Composting Grubs?

They are shipped with USPS priority mail, and will arrive at your doorstep.  However, if you'd prefer them to be held for pick up, we can mark the package "Hold at PO for Pick Up" and the post office will call you when they arrive.  You will need to notify us that this is your preference.

Do you guarantee live delivery?

Yes.  Composting grubs are very hearty.  They can tolerate warm climates, and cold climates.  This means they can help compost all year long (assuming your compost pile is not frozen).  

What should I do after getting them in the mail?

If you have an active compost pile, the best thing to do is add them to the compost.  The transit dehydrates them a little bit, but the decaying material in the pile will help hydrate them and nourish them.

Difference between Composting Grubs and Composting Worms?

Red worms are the traditional composting worms.  Many people purchase them for vermicomposting, to help break down decaying material, and to create that amazing, black fertilizer.  But composting worms don't have the production skills that composting grubs have, and their diet can tolerate much less.  

Firstly, composting grubs will yield much more compost than red worms.  Red worms will consume and produce about their body weight per day in compost.  That's not bad.  But Black soldier fly larvae will produce between 1.5x - 2x their own weight per day.  They're nearly twice as productive as the red worm for composting.

But the biggest benefit is that black soldier fly larvae will compost nearly anything.  Red worms are very limited with what they can compost.  They can't break down meat, dairy, or citrus products.  These will all kill them if introduced to their compost pile.  

On the other hand, black soldier fly larvae will break down these material, and also spicy foods, fatty foods, and oily foods.  There is almost no limit for what they will not consume.  You can catch up with more details on the amazing differences between red worms and composting grubs here.  

How much can composting grubs compost?

Composting grubs are extremely hungry and will consume nearly double the amount of traditional composting worms.  1 pound of composting grubs will produce 1.5 - 2 pounds of compost per day.  That's an amazing yield, and will help any avid gardener create their desired compost or compost tea.

How many composting grubs should I buy?

It's not an exact science.  But we recommend 10,000 black soldier fly larvae for 15-20 lbs of scrap food in a bin that has a base that is 3 square feet.

How to set up a composting bin for composting grubs?

Black soldier fly larvae go through a metamorphosis.  Which adds a little bit of complexity to their compost bin set up.  As the grubs grow older, they will become darker in complexion.  This is a sign that they are ready to transform into the pupas, which they'll then turn into harmless soldier flies.  

Having said that, our composting grubs are very very young.  Which means you'll maximize their composting abilities.  We wrote a complete guide on how to set up a proper black soldier fly larvae composting habitat.

Are composting grubs good for the environment?

Yes.  When food waste breaks down naturally, it emits methane, a potent green house gas.  Black soldier fly larvae help eliminate this by breaking down the material before it has a chance to produce that methane.  This is the first step when building a small scale circular-agricultural set up.  By allowing your composting worms to breakdown your waste, you decrease your dependence on external compost, and utilize the compost produced by your composting grubs.  

Once you've created amazing organic fertilizer, you can then enrich your gardening capacity with greater, more fruitful yields.  This, again, reduces your dependence on external food sources, which fulfills the circular-agricultural cycle.

Can I add them to my garden?

There is no benefit to adding composting grubs to your garden.  They will not aerate through the soil, and are likely to get eaten by birds.  Like composting worms, they will only eat decaying material.  So there is no concern that they will eat living plants.

Can I feed them to my chickens or reptiles?

Absolutely.  Chickens love black soldier fly larvae.  Black soldier fly larvae are loaded with copious amounts of calcium.  This means they are great for egg-laying chickens, and also for male chicks and chickens.  The calcium boost will help yield stronger bones, which will help the chicks grow into meaty meals.

And they are amazing for reptiles.  Most domestic reptiles need a high amount of calcium.  Dusting common feeders like crickets and superworms with calcium powder is a common solution.  But the best solution is when your feeder insects naturally inhibit the calcium requirements, and black soldier fly larvae have those nutrients.
