Bokashi and Red Composting Worms

I’ve seen a lot on the internet about Bokashi and red composting worms.  Several sites recommend adding Bokashi fermented food scraps directly to the composting worm bin.  That would be much easier than digging holes to bury the Bokashi fermented food scraps.  Usually Bokashi buckets are 5 gallons each.  When it is full that is an awful lot of Bokashi compost to add to a worm bin. Unless you have huge commercial sized worm bins.  So the first problem is the amount of Bokashi when it is ready is too much for a home-sized worm bin.

Bokashi and Red Composting Worms-Is it OK?

Bokashi and red composting wormsAnother problem of putting Bokashi fermented kitchen scraps into a worm bin is that it is very acidic.  Red compost worms also known as red wigglers can tolerate a wide range of ph in the bin.  But they can not handle too much acidity.  When the Bokashi food scraps are first finished they are too acidic for a worm bin.

Posted below is a YouTube video of some Bokashi and red compost worms.  You can see the worms reactions to the acidity of the Bokashi kitchen scraps. It is very clear that they are in distress as they writhe around trying to get away from the acidity.  In the picture to the left the two worms that are curled up are actually writhing in distress to the Bokashi.  The Bokashi is the brown powder that you see in the picture.  The vegetable scraps in the picture are fermented by the Bokashi microorganisms.  I wanted you to know that after I saw the worms’ reactions I removed them from the Bokashi fermented kitchen scraps.

Let Bokashi Compost Sit for a While

it is important to know that Bokashi fermented kitchen scraps need to sit for a while exposed to the air before being added to a worm bin.  Or just add small amounts at a time.  This way the worms can steer clear of it until the acidity has worn off. Bokashi fermented kitchen scraps should not be buried near roots of plants that you care about.  The acidity could harm the roots before it becomes neutral. The acidity dissipates quickly when it is buried in the ground.

Just a Few Tips on Bokashi and Red Wigglers

So these are just a few tips to keep your worms healthy and in the proper environment.  The thing about the Bokashi kitchen scraps is that they are great after they lose their acidity.  The worms really love eating  it after it has a more neutral ph!

Feeding Red Wigglers to Garter Snakes

Feeding red wigglers to garter snakes is questionable.  I often thought that if you have a snake that it would be great to raise composting worms.  You would have a constant food supply but that doesn’t seem to be the case.  Feeding red wigglers to garter snakes can be toxic!

Feeding Red Wigglers to Garter SnakesThe Latin name of the Red Wiggler is Eisenia Foetida.  Foetida means smelly.  This refers to a smelly yellow fluid which the worm releases for several different reasons:

  1. Stress from being handled
  2. To re-moisten its body when drying out
  3. Exposure to light
  4. Defense mechanism when threatened

Red Wiggler Releasing Coelomic FluidMany people think that the yellow fluid is urine. It looks just like urine but it is not.  It is called coelomic fluid and it can smell like garlic according to Edwards and Bohlen (1996).  The evidence that the worms are toxic doesn’t seem to be consistent because some people report feeding them to garter snakes without any problems.  Some pet manuals don’t make a distinction between red wigglers and night crawlers.

Evidence that feeding red wigglers to garter snakes can be toxic.

Lani Lyman-Henley who is a biology professor and snake ethologist wrote the following message to the gartersnake mailing list in 2006:

I can attest to the toxicity of red wigglers.  I saw its effects myself on a pretty large scale in about 1989. I was told by our lab manager (an excellent herpetoculturist and published biologist herself) that she did find documentation (seconded by our vet at the time, also published in reptile veterinary work) that Eisenia species (compost worms, red wigglers) can produce coelomic fluids toxic to snakes (and I’m sure other creatures). It appears to be derived from their diet, but we never isolated how.  We actually raised our own for some time, but gave up on pursuing this since it was just too risky and there were safe worm food sources available.  Any Lumbricoid “leaf worms” are small versions of nightcrawlers that are just right for smaller snakes, and most of the soil worms you’ll find are relatives.  I don’t really want to remember the dozens of baby snakes that literally puked themselves to death on just one meal of toxic worms.  Even though we’d had many safe meals, not knowing what caused the one batch (same supplier, same packaged diet) to be so much more toxic, we didn’t want to risk it happening again.

It is too bad that red wigglers can be toxic to the garter snake.  They are cheap, easy to buy and to raise compared to nightcrawlers (Lumbricus terrestris) and related worms known as leaf, dew and garden worms.
