FIVE WAYS TO KILL A MILLIPEDE

Ironically, when I got my first millipede (after a 20-year hiatus keeping invertebrates) I searched online for care information. To my distress, the majority of what I found was how to kill millipedes, mostly from our leading pest control circles. I constantly strive to provide better care for my amply footed friends. But sometimes with our best intentions, we fall way short of the mark. Like way on the opposite side.
  1. A DROP or accidental fall is almost always fatal. A millipede is designed with legs that climb, dig, hold, grasp, etc., but sometimes even 500 legs can fail when they are in your hands. If you must hold your millipede (and please do!) just make sure it has a substantial grip on you and never hold it above a hard surface or more than a foot or so above anything. Watch how it’s legs move – it is mesmerizing it can keep track of that many legs. I can’t seem to keep two in order sometimes.
  2. DIGGING accident – I’m not talking about when the millipede digs; I am talking about when you dig. Your millipede will disappear. You won’t see it for days and maybe weeks. I lost one for a few months once. (She was busy laying eggs.) Whatever it is doing in the subterrain, is something it needs to do without your help. Most likely it is molting or laying eggs. When a millipede molts, its body is super soft and can be easily damaged. Your touch cannot be gentle enough against this little Jell-O body. Give it time. But what if it died? That’s part of living, we need to accept it, but we cannot bring it back to life so digging is futile. If you have the urge to dig, go shopping. Go eat some ice cream. Go play Free Cell. Don’t dig. Just don’t do it. Having several millipedes holds a better chance you will see some on the surface.
  3. DESSICATION – a screen top is not a millipede friendly cover. Most species of millipede need 80% humidity or even higher. This is easy to accomplish with a moist substrate or by misting the enclosure a few times a week. (Make sure the bottom layer of substrate does not become saturated.) Temperature is also important and can be a point of confusion. Even tropical species prefer temperatures under 80˚. Below ground is cooler than above ground – think of a root cellar or basement. These millipedes come from areas with a forest cover (super shade) and are under ground, so much cooler. The ground also holds moisture, which is also cooling.
  4. Introducing UNWANTED PESTS – I know there are pros and cons to both sides of this issue. I used to collect soil, leaves and wood outside for my isopods. The last time I cleaned their enclosures I found all sorts of undesirables. Now I use the sterilized stuff for them, too. Once I mix a batch of substrate (all ingredients have been baked) I let it sit for about a month. During this time, I stir it to keep anaerobic bacteria from growing. I watch it closely to make sure nothing lived through my oven. When I do finally use it, I add springtails and they start the process of balancing the substrate. No matter which path you choose, there is a process of balancing the substrate. But the path that eliminates outdoor pests is more appealing to me. If you choose to gather things out doors, be super careful not to include ants, beetles, slugs, earthworms, isopods, etc., etc., etc.
  5. STARVATION – you may not think this would be a problem for “dirt-eaters”. But “dirt” has many components such as rotting wood and leaves. Coir (coconut fiber) offers no nutritional value and some people believe it could even be detrimental if ingested. Most experts say at least 50% of the substrate should be edible (rotting wood and leaf litter). The wood should be soft and crumbly, never black. If there are other invertebrates living in it, it should be fine. The leaf litter should be at least a season old. Most millipedes love cucumbers, apples, mushrooms, mangoes, corn, etc. but these foods should be considered treats or supplements. Their primary diet should be the substrate.
Millipedes generally have long lives. With just some basic care, we can be certain they reach their natural end.

All good information; everyone with millipedes needs to read this.

Somebody sticky this and the substrate recipe. Better yet, add them together and sticky the whole thing.

This is such a good post, there really isn't much info on their care at all and starting out I had to scramble for info and am still learning.

I had to learn about the digging one the hard way last year when I used to try and check on them. I accidentally uncovered and nudged one of my desert mills while it was molting and had no idea what to do and it unfortunately passed. I no longer touch my millipede's substrates unless I see them all on the surface.

I'm starting my tank in winter, and don't have ready access to rotted wood. Would it be alright to order substrate from bugsincyberspace? They have a compost and oak chunk mix that sounds promising.

I think most of us have had an unfortunate experience with this. This seems to be a common issue with new keepers. If you only have one or two, it's harder to keep from being curious. My cure was to fill my spare bedroom with them. :rolleyes:

BiC substrate is okay but IMO it doesn't have enough wood for larger species. I've never bought the oak chunk but this will probably be fine.

I had a terrible revelation. I live in rural New England. I don't need to buy rotting wood. I just need to pull over and drop a log in my trunk on my way to work... But what's a good soil to use as a base for my substrate? I have compost I could use from my vermicomposter.

The wood becomes the soil! I buy organic leaf compost and mix that, the wood and cocoa fiber. Make sure you don't pick up pine or cedar - those are not good for millipedes. Most hardwoods are good; oak, maple, beech, hickory, birch, etc.

I would stay away from worm castings as those little slimy suckers absorb all of the things that millipedes need. I use cocofiber as a soil base or just more leaf compost with a little soil and peat.

Other things to stay away from (besides resinous wood like pine and cedar) are perlite, vermiculite and fertilizers of any kind. Worms use the good stuff in substrate way faster than millipedes.

Oh cool, thanks for the advice. My area is more heavily wooded by deciduous over evergreens. So I feel safe in picking something readily rotted, so long as I can identify the bark and branching patterns.

Sorry to revive an old thread, but I feel like the information here could be useful to some newer members!

What's wrong with using vermiculite? I know it's commonly used with centipedes and other inverts, and I've seen several people state that they use it for their millipedes with no issues. I don't personally use it myself, but I'd love to know the reasoning for why others shouldn't!

#1 I have dropped a few specimens accidentally over the years and I have been surprised that many do make it through some pretty massive cracks and bleeding.
#2 If I had a dollar for every immature I accidentally ripped in half doing basic maintenance I'd have a million more dollars.
#3 Small immatures can desiccate if the substrate isn't damp even at 100% humidity.
#4 I feel like people who suggest it's bad to sterilize substrate can't possibly have long-term experience with any individual culture, but maybe with years of short-term cultures.
#5 You can add wood pellets to depleted substrate with some success.

Vermiculite just isn't useful in a millipede tank; inedible, hard, unnecessary for a moisture retainer in a proper substrate, and it can adhere to the exoskeletons of the millipedes and cause problems with molting (besides just being unsightly).
I don't think it is recommended for centipedes for similar reasons. A small amount wouldn't cause problems, but there is zero need for it and its more likely to harm rather than help.

Hope I'm not mixing it up with another substrate additive, but I think that's why vermiculite isn't generally recommended.

Thanks,
