View Full Version : Mold as a substrate.....

.... is exactly what you end up with when you use Aspen shavings in a humid environment. :)
My quest for the perfect substrate for my humidity lovers continues. This weeks stab in the dark: Sphagnum moss. Right now, I have our Columbian Rainbows on damp sphagnum, as well as the blue beauties. So far, it's got the humidity up to the point where it is consensing - which is great for the rainbows. Not so great for the beauties, even though they still seem to be content.
So far, I've decided NO on newspaper, and for cost reasons alone, even with my "dry" (or Dry-ER) snakes, Aspen is just getting too expensive. Paper towels thus far have done very well for the Kings, Corns, and Balls. Seems to be ok for them.
I've been unable to locate Cypress mulch anywhere.
What I wanted to know is, what are your experiences with sphagnum? Does it clean easily enough? Have you had problems with it getting TOO humid? But most especially, how well do you find it resists mold?

I wouldn't use it. Not while they still have newspaper presses up and running.
Sphagnum moss is infamous for hosting a microscopic and highly toxic mold, Aspergillus. It's a leading cause of aspergillosis pneumonia in snakes and turtles.
I like the ground coconut husk substrates such as Bed a Beast or Eco Earth. They are heat processed in order to dehydrate the fibers and that effectively denatures the proteins in them so they cannot support much if any mold growth.
I use the coconut husk for my humidity loving reptiles with great results. I honeslty cannot say I've had a problem with it before.
Here's a tip though - buy it at a greenhouse. It will look the same (be in a 'brick) but be under a different name. Usually it costs 1/2 to 1/3 the price than if you bought it in a pet store.
Sphagnum moss is also acidic. We need to get more cypress though, we're out of it.
Well just out of curiousity..... I use out-door dirt for all of my varanids, it holds extreme amounts of humidity, and I dont have any native snakes near my immediate area.. Why not just use outdoor dirt for a snake, if you live in the city away from any wild snake populations?? I would assume it would be just as good for your snake as it is for my monitors... Everytime any moisture goes into it, the humidity stays at a perfect level... just a though.. Criticism welcomed as well, as iam trying to find a better substrate for all of my reptiles.... And of course, been toying with the idea of using outdoor soil.
Oh yeah, forgot to mention it doesnt mold at all.
Monitors tend to have more immune system protection from pathogens than snakes do, not surprising as they are more likely to eat carrion. Snakes are far more prone to respiratory infections from the bacteria and mold that soil harbors. Garters and a very few others do fine with soil but I wouldn't use it for most snakes.
Outdoors soil is exposed to wind, rain and sunlight that help to keep pathogens down to a reasonable population, once removed from those things it's tough to keep dirt clean enough for most captive herps.

Put soil under a microscope and you might be shocked to see how much microscopic mold it harbors.
Hmm but my debate really is, is it any worse then the stuff pet stores sell and its free? I honestly think its better.. But iam still very reluctent to put any of my snakes on it..

Invictus, a couple things....
To start with Columbian rainbows,E c. maurus, don't require the extreme high humidity that Brazilians do. They are commonly kept on dry substrate with a large water bowl, similar to common boas.
For Brazilians, Bloods, and Anacondas I have used
ordinary cheaper than dirt "PEAT MOSS"...
It is simply Spaghnum, processed and ground up . It's fairly sterile and is compressed into large bags. Its dry when you get it, so there isn't much living in it.
You can get huge bags, from Canadian Tire, Walmart, or Garden Centres for only a few bucks.
Yes , the plant by nature is acidic, and that is why you want to use it, because the low pH inhibits mould and bacterial growth... You wont get any fuzzy stuff growing on peat!!
The only draw back is that you must keep it moist, because it is very dusty in the dry powder form.
I used to simply pour a small bucket of water in the cage when the substrate starts to get dried looking.
The snakes pat it down into a pretty solid mass, so the dust issue isn't critical unless you're removing the substrate or putting new in. The dust isn't toxic or anything, but it can clog nostrils, and make the keeper sneeze.
This substrate is also safe to feed on, and thats another big plus.
I've lost snakes on cyress mulch do to ingestion of the long sharp toopick like bits that come in it... So if you use Cypress, you better feed somewhere else, and as your collection grows, you'll find that a big pain in the butt... at least I did! I feed everything in the cage that houses it.. No time for musical chairs
Give Peat a try.... its dirt cheap,,, no actually its cheaper than potting soil.
Jeff has a good point though... Paper is free
I currently keep only dry species and have them all on Alpha or Beta chip made by Nepco . Not sure if you have a supplier out your way, but these are lab grade particulate substrates.
They can be spot cleaned, and I also feed on them..everything except small newborns...

Peat, like sphaghnum, is a common culprit for aspergillosis pneumonia. Too high in protein so it supports the growth of all sorts of nasties.

It all depends how much vegetation and other organic material is in the soil. If you're digging stuff up from a dry, sandy area it's probably safer than the moss and wood-based stuff you get in petshops. If it has a high vegetation content it might be even more prone to pathogen growth than packaged substrates.

Rainbows do exelent on oak leaves litter, just try it and see!

I have to agree with Roy on every point. We've also had the neverending search for the best substrate (even tougher cos Katt's allergic to wood shavings) and eventually settled on peat moss too. We use it for everything from, dry snakes to humid snakes. Only setback to it is that you'd have to spray it down lightly every 2-3 days.

The trick with any substrate (when it have to do with humid conditions) is NOT to keep it always humid...
Terrariums for spp that needs humidity, must dry once every day.
Small openings for ventilation and drying once a day.
That's all i do with any substrate for humidity i use.
Otherwise, whatever you do, you will always have problems with molding spots in the terrarium.

one trick I heard of for high humidity animals is the use of open rubber door mats, the ones that are 1-1.5" thick and probably the ground rubber used in playgrounds would work as well. Cleaning would be more tedious but a rinse and drop into boiling water(maybe a bit of disinfectant) makes it reusable so after the initial costs it should last a long time. Just an idea from outside the box.

Well here is my story at the Zoo we had a green Anaconda that was removed from her pond and placed in a 8 X 4 X 4 cage and all I did difrent with her was spray extra in the mornings a rule of thumb is that your cage must be dry B4 you spray your cage and it must "LOOK" dry 1-2 hours after spraing. By doing this I got 100% sheds all the time.
I was under the impresion that condensation was bad. cause condensation is more then humidity it is evaporated water that has no where to go but on the sides of your cage.
and to get that kind of humidity your substarte is VERRY wet not damp but wet. I just learned that a wet substrate can give you a lot of problems so I would be verry carefull.
I dont know how your herps are set up so I dont know what kind of guages you have but I would get a digital hygromreater to tell you what the humidity is at any given time you check your cage.
to have 85% humidity is one thing but to have condensation I think that only hapends affter 100% humidity.
I am not an expert but that was just my experiance with that animal in general. All my animals are verry easy to keep content but you have humidity loving animals.

No, you're right on that one. By the time the air becomes saturated enough with water to cause droplets to form, your ambient humidity is 100%.
I underestimated the ability of moss tohold moisture, so we're going to be taking another run at it just putting in dry moss and misting it down instead of soaking it first, then mixing it with dryer moss to distribute the moisture. So far it's worked well in one of the other rubbermaids... no condensation, but the air is still nicely moist.
For my snakes I use newspaper, paper towel, or bath towels. All work great. The leos get the papertowel as well. For my tortoise, snails, and frog I use peat chunks. As Roy mentioned, a bonus in using this substrate is that you can safely feed on it, unlike most other loose substrates. Because it is so acidic, it resists mold as well. I kept my rainbows on sphagnum for all of 2 weeks. I hate the stuff in that application. Its too messy, and it's impossible to spot clean.

I am going to have to disagree here. Condensation can be caused by numerous things. It can be caused by temperature, ventilation, or where the evaporated water collects. Condensation can definitely occur in drier environments as well......far from 100% humidity. Have you ever noticed on windows in buildings during very cold weather how sometimes you will find condensation on the windows? This is due to temperature difference on either side of the glass. This can occur in 30% ambient humidity. Several of my enclosures have condensation, none of the ambient humidity levels ever reach 100%. The moisture doesn't escape quick enough due to controlled ventilation, so it gathers on the sides. Condensation is not necessarily a bad thing. All depends on the situation and cause.

I'm quite surprised they would use a product like alpha chip in any lab settings due to the fact that it is made from softwoods. All softwoods contain phenols which have been proven to be the cause of such problems as respiratory problems, neurological damage, and liver/kidney damage in small animals and reptiles. This issue would no doubt have serious consequences on any testing the rodents would undergo, since their immune system and ability to process would be compromised.

I've never heard about this nutrient-rich substrate being used for snakes...but I did try to find some for my millipedes. Now one would assume it would be easy enough to find! I went all over the place, parks, forests, everywhere.....came back empty handed :confused:

Ever put peat under a microscope? I've seen more microscopic yeasts and fungi in peat than in most topsoils. And the types of mold peat does harbor tend to be the ones that produce a lot of mycotoxins. I see a lot of respiratory, skin and digestive tract infections caused by peat substrates.
I think the only substrate everyone agrees on is paper towel.
However, I use peat b/c I hate when paper towel gets wet, snakes poo and then smear it all over, getting themselves covered in it. Even for just a few hours, some weird skin infection can set in. No thanks! I'll take my peat moss any time of day. That bacteria that was mentioned. Asperguillis (spelling?) is found in the air anyhow. We inhale it all the time.
Aspergillus is a mold, and yes, it's found in the air, but not in a form where it emits mycotoxins. It's when it combines with a protein source such as soil, peat, etc. that it becomes nasty. In the air it's not really feeding off of anything and so not producing any nasty metabolites.

Isn't it just made from Aspen (like beta chip is)?? If so, Aspen is NOT a softwood. Hard wood all the way. And not only that, its tops on the list for the least amount of extractives (bad thingies).

Are not the mucus membranes proteinaceous?
Since it's in the air, could it not settle onto any other substrate (aside from news paper) and start to grow.
Mucuous membranes have more immune system protections such as T cells and lymphocytes than protein, so the odds of aspergillus growing in the membranes is very small unless it's an immunocompromised individual. Most of the time when you find aspergillus in nasal swabbings it is in the process of being flushed out of the body by increased mucus production, rather than recently inhaled stuff. Aspergilosis is normally a result of inhaling or ingesting whole colonies of the stuff at a time rather than just inhaling stray airborne organisms.
Yes, it can grow in almost any substrate in small quantities, but soils and mosses are the ones that provide the most fuel for it to develop into colonies capable of pumping out mycotoxins. It actually does grow on newspaper and any other paper product, but not in amounts that tend to threaten healthy animals. There isn't usually enough protein in paper products to support more than a few generations of the stuff so the growth is self-limiting.
