Will a Red Worm Population Double in 3 Months?

One bizarre vermicomposting “fact” that has been floating around for years, and taken seriously by many newbie vermicomposters, is this idea of expecting your Red Worms to double in number in 3 months (or “90 Days”). It seems like a fairly reasonable claim on the surface – but if you really sit down and crunch the numbers you’ll realize pretty quickly just how utterly ridiculous it is!

For starters – even regardless of any fun calculations you can make (something we’ll do in a minute) – it’s hugely important to remember that Red Worm reproduction and growth are both HIGHLY dependent on a wide range of different factors. Some of the most important include 1) temperature, 2) moisture content, 3) population size, 4) food value and overall availability.

But just for fun, let’s crunch the numbers anyway!

For our little thought experiment, we are going to assume that we’re starting with
100 adult Red Worms

Some Other Important Assumptions

- Fairly close to “ideal” conditions – 25C / 77F temps – good moisture, ample nutrition etc
- 3 cocoons produced per adult worm per week*
- 3 juvenile worms hatching from each cocoon*
- 21 days incubation time until cocoons hatch*
- 42 days to maturity*
- 12 week period – with final tally being made at the END of these 12 weeks (still, technically a little less than 3 months)
- For sake of simplicity we are basically assuming that all cocoons are dropped at the end of each week – so each cohort will hatch/mature at the same time. This is obviously not how it would happen (cocoons would be laid throughout week) – so our final tallies are actually going to be lower than they should be.
- There are NO worm mortalities during the 12 weeks

*These figures are based on those shared at the end of this post: Crazy Q&A Podcasts – Session #13 (most closely resembling the figures calculated by professional worm farmer, George Mingin)

TOTALS

2800 Adults
5400 Juveniles
9000 Cocoons

SO…

We’re looking at a potential 28-fold increase in the number of adults alone!


Of course, a typical worm bin probably won’t see growth rates like the ones shown above since people often start with a fairly large quantity of worms in a relatively small container. BUT, it really does give you some idea of what’s potentially possible if you give the worms plenty of space to spread out in, and just generally take good care of them!

Bottom-line – it’s safe to say that unless you are really messing up, you should definitely expect to see much more than “doubling” of your Red Worm population (especially if you are counting juveniles) within a few months!

Bentley, I have a problem, there is something growing in 2 of my bins [worm factory]. It looks like a little plant, green & purple teardrop buds w/a lot of lacy roots. It’s growing on the inside corners & underneath the bins, hanging down. Looks scarey & I’m wondering if it will hurt the worms. Have you any idea what it might be & should i worry about it ??? Thank you, Suzan

Woot! I got gifted a bin some time in July and that bin seems to be producing VC at a crazy rate! I have since harvested twice and have removed worms to add to 2 other bins and 1 worm inn :D In fact, that original bin is out pacing my worm inn! Makes me wonder what I am doing wrong with that worm inn! LOL

Thanks for this post. I was wondering if I was imagining the population explosion :D

Great experiment. I have my compost worms in an outside 3 metre garden that is just for them. I find that they still spread throughout the backyard gardens.

started with 3 pounds of worms put them in 3 greenhouses and now you cant move any dirt without finding lots and lots of worms. Not selling but giving them to friends for their gardens. Will I get to many for my crops? We make our own compost and the little creatures seem to love it. The greenhouses have auto watering system twice a day 10 min each. They love the wet.

So, this is not the case for me.

I started my bin in April. I killed most of my worms (it’s a learning curve), and I had two worms left. They are matured and now, in October, 6 months later, I have 8 mature worms and that’s it.

What am I not doing?

One plastic bin on my shaded porch. I freeze our kitchen waste and add it (once it’s de-thawed and room temp) with plenty of newspaper and cardboard bedding.
I feed it once a week and I turn the bin… well with my hands.

Also, since I have so few worms, I feel like I cant harvest the ‘dirt’ because it still has egg shells and newspaper shreds in it.

How can I get it to a dirt state? (I don’t have a garden and need to be able to give this to people to use on theirs)

THANKS in advance.

If each adult produces 9 juveniles per week, then once the population age distribution stabilizes, the doubling period will be 19 hours.

The real question then is what limits growth? Food supply? Waste elimination? Disease? All of the above?

My home bin started with 2,000 worms 3 months ago and is healthy but I’d like it to break down more of our family-of-four food scraps. I tend to watch them closely and turn their bedding just to see how they are doing every other day…sometimes daily. Am I bothering them too much and disturbing cocoons? Any suggestions on how to get them to breed faster?

#10. January 29th, 2014, at 11:29 PM.

Kathy,

I started with 5lb of worms in April and killed all but two of them (bc I wasnt adding bedding, woe is me). So I pressed on and got up to 8 worms over the course of 7-8 months. I fed every week and turn.

BUT!

I missed a week, so two weeks went by until I fed and turned again and there were a ton of new worms! So I started to feed/turn every two weeks and I have an innumerable amount of new baby worms that are maturing to big fatties!

So to answer your question, YES! I think you are disturbing them. I wouldn’t check on them unless you re feeding them.

I hope my experience is helpful to you.

hi,

my (short) experience has quite accurate numbers.

30/8/2013 – started a 19L bin with only 12 worms (large juveniles, not adults).

14/2/2014 – completed a larger FT bin, and moved them all to it.
i screened the unfinished material by hand, and put the adults and large juveniles in a little plastic box. (i move the small juveniles with the vermicompost straight to the new bin)
then, i counted the worm and reached to 427 worms. i assume that the number of the small, unlisted warms is pretty much the same….

that’s give me a whopping 71 times increase(!) in half a year.

I started composting only on March 20th 2014, I.e I took the first steps. I contacted our neighbourhood juice shop & asked him whether it is possible to pick all the food scraps from his shop in the night before he closes for the day. He said come at 9 pm & collect the whole bag, we dump it in the BBMP bin, (I live in Bangalore), at 9.30 pm if you come you can collect else we dump it. I said great! The next day (21.032014), we picked a carry bag which he had filled with diff types of scrap & juice filterate which was wholly Sapota, orange peels, a few peels of apple & may be some vegetable scrap. He had kept all in assorted bags, so thoughtful of him. (I had been preparing for this for the last couple of weeks–reading up on the stuff, watching stuff on YouTube etc).
Suddenly, I was in a great hurry now. I immediately started off, –in the open yard–on the South side of my house I have a passage of about 2′ x 30′ & this is also the ideal place for vermicomposting as per Vastu as well. As I did not have the bins/trays etc & I did not want the scraps to rot I started off open cast. I spread out all the vegetable & fruit scraps on the ground which I sprinkled with water to moisten it.
As I did not want to spend a great deal for this project I had been asking the neighbourhood shops if they had any spare trays, I checked olx & other websites etc. No go!
On 22nd I picked a kilo of red worms from Vruddhi composters in Peenya for Rupees 600/- per KG. Wah! This was moving now, and fast! I was now the proud parent of about 2000 red wriggler worms. Of course, I could not see so many of them but that’s what the seller said.
On 23rd I was fortunate to connect to a lady who had 25 trays too many (one of the vegetable shop keepers had referred one of his cx who had an excess of trays), & was looking for a buyer, to my luck the trays were perforated all around (see pictures & video on YouTube), I bought 6 of these from her at ? 150/- each. These bins were brand new 60 litre size, unused as yet & I was lucky that I got it from her. Now my vermicomposting project was really taking off. I spoke to the street sweeper who swooped a bagful of leaves for me. Now, I quickly gathered a few cardboard boxes from the neighbourhood shop, tore up newspapers & carton boxes, wetted all the stuff in a bucket of water & laid the bed of cardboard, torn bits of newspaper raddi, & made a neat bed for these lovely worms. I filled the tray to 60-75% with the dry leaves! sprinkled a little bit of sand! & mud all over & sprayed water on it with a small plastic pot with holes in it.
Now, I started scooping up all the fruit & veg bits which you will remember were in the open cast pit till now. My happiness on seeing the worms still alive and kicking even though I had introduced them in the open pit earlier was great! It was great feeling, to realize that I had not harmed my babies.
I repeated the same process with another bin too, and I was quite surprised that just one days fruit waste from a juice centre was going into two large trays. The fruit waste was about 3-5 kgs aprox. & the bins were like around 60 litres capacity. In a couple of hours I had completed all this. Of course I kept layering the browns & the greens, spraying water, adding fruit& veg waste etc regularly. By the end of these two hours I had scooped up all the stuff from my open yard compost area into my new compost bins.
I cut up a suitably sized piece of banner material cloth–HDPE stuff & placed it at the bottom of another new tray which would be my collection tray for the compost tea. Now I placed this firmly on the ground, in my 2′ passage which is incidentally covered with plastic transparent, fibre sheets as a roof but still provides some light & sun light, but the suns intensity is greatly reduced. I now hoisted the other tray which was filled with all the fruit-veg-waste, leaves, worms & all on top of this collection tray. I Repeated this process with another set of trays as well. Now I Sprayed both sets with water one last again. The advantage of using this pre-perforated tray system is, that I am kind of sure my pretty worms will never wallow in an excess of water, nor suffer for want of sufficient ventilation because the trays are fully perforated all around. I now Covered the whole thing with a black cloth which was readily available at home. I covered this with a mosquito mesh screen which was from one of the windows to keep pests at bay.
I have been watering & spraying regularly. Once in a while I can’t resist searching to make sure my worms are all fine. This morning I added one more tray because I scooped up another bag full of fresh yellow flowers which you will find all across Bangalore streets which are mostly tree lined avenues. Repeated the whole process of bedding, browns 60-70%, cardboard, paper, water, leaves etc all over again. The only difference is that I have filled the third tray with flowers which were strewn on the streets instead of fruit-veg strips.
One more thing I forgot to mention earlier, I have also used a number of coir husk (outer ‘nar’ part of the coconut). I also used a scissor to cut the coconut dried leaf into smaller bits, which also went into all the three the tray.
Great was my joy when I started digging & turning over the stuff in the previous 2 trays in search of a few worms, and found so many wriggly-quiggly fellows scurrying all around & trying to escape getting caught by me. I quickly gathered about 2-dozen of these worms & introduced them into the third tray which is mostly full of a variety of flowers, except for the bedding etc.
I regularly collect the comp-tea & distribute them into all my pots & also garden plants. I make it a habit to water these trays first thing in the morning.
All in all my vermi-composting project is going great for a first timer, even though I have been gardening for at least 40 years.
I will keep you-all posted on my progress again shortly.

Hansie – I definitely wouldn’t recommend mixing most ordinary fishing worms with composting worms. For example, one of the most popular fishing worms – the Canadian Nightcrawler – is a deep burrowing, soil worm. It will NOT thrive in a worm composting system. Unless you know for sure what kind of worms you are dealing with, it’s best not to make any assumptions.

Cliff – you MIGHT do ok with something like Alabama Jumpers, since they are more of a soil worm (likely fairly tolerant of warm temps as well), but my usual recommendation is to create composting environments close to your gardens (or within them) and just stock them with composting worms. Vermicomposting trenches/pits and worm towers are two examples of systems that can work really well in association with gardens. As for the number of worms – I would definitely start small, and make sure you’ve mastered the process before going too crazy. A mistake people make is buying loads of worms (spending loads of money in the process) before they really know how to care for them properly. You can imagine what often happens in that case!

Hey all you farmers out their. We just acquired a place on a mountain in Northern Arizona. The Dewey area. In observing the local habitants with the large bins and the worms that we put around the trees when we moved and didn’t have a bin for our wiggly pets. We started noticing that the lizards and birds love the grubs. They don’t eat or dig the Red wrigglers. Each lizard seems to consume 3or 4 of those pesky grubs per meal. The long beaked birds really go for them also.
I read how long it takes the worms to go from egg to adult. We have been here for 11 months. got a lot of babies. But, the adults seem to be alluding us. I mean, we can find some but not as many as there should be for this many months. I stuck on this one.
Thank you for your comments.

RR – definitely MANY factors that can affect reproductive rate. Outdoor systems unfortunately are much more difficult to keep under control, so I’m not overly surprised by what you are encountering. Feel free to email me with more details and I’ll see if I can help:

EVE – 100 worms will need very little in the way of food. Mix lots of moistened bedding (shredded cardboard or newsprint are great) with a handful of compostable food scraps and let it sit for at least a few days before adding the worms. The key with that many worms will be to avoid overfeeding!

Hey Bentley I want to thank you for your answer the last time I wrote. It has been awhile. There’s a few things that I found out since the few months that I wrote last.
I wrote that we have outside bins and couldn’t find our adults. FOUND THEM!!! We have the dry horse manure and dry yard debris pile just outside of the wood bin. They are huge and thriving there. So, we just count this as a bin. They don’t go beyond the pile. They seem to be perfectly happy. Another thing that we found out was to put decomposed granite around the bin. They stay clear of that stuff. Then again makes sense. Rock only breaks down so much. I need to make it clear at this time that the bins that I speak of now is to be used for the fishing side of this company. The use of pine needles is great bedding and food for the little red darlings. On the composting side? I believe that it is better to have them in a controlled environment for best results. But, back to the outside bins.
I notice that we have a great many white worms with legs, I think they’re called grubs. Been actually thinking about making a bin just for them! Took a few fishing one day. When hooked they bleed a dark black excretion that seem to attract the fish. Didn’t hook anything, the fish went to school and learned. lol Didn’t take any of the grub home either. Now as far as the composting side of this grub. I noticed that they leave behind them pellets. Compared to the fine compost the wigglers leave. My question on this is…. Since they eat the same thing as the wigglers, is their compost good for sales?
I’m kind of stuck with my business plan. I am at the point of obtaining investor for the farm to get up and running. But, the question of the day is…. Where do I get the stats on the potential for this business to show the investor that this is a lucrative business. I am also stuck as to what a good competitive price is. I wonder if you could also turn me on to a good packaging company. These are the things that are stopping me with the plan. Without knowing the latter forward the plan. Packaging of course must be included. Also, do you offer worm containers w/lids? I have checked out all over the net and only found one place so far that has containers specifically made for the packaging and sales of fishing worms, tea bags. Really would appreciate your help on this one.
We are hoping to be in full operation by the first of the year. This intels a few buildings with control climate, 30 and above pounds of worms, and lots of clean dirt, coffee grounds, eggshells and such. Will let you know when this happens. Let me know if you can give me a deal on the worms.
Thanks Bentley and all of you for your help before, now and in the future. Have a great holiday.

I am coming into this WAY late, but I thought I would clarify something. Conventional wisdom on vermiculture says that, given the right conditions, the total boimass will double every three months. Since many of the new worms will be juveniles, to double the biomass, you need many more than double the worm count. Your numbers show that you can have many more than double the number of worms, but the total weight of the worms should be double what you started with.

Hey Scott – you raise a very interesting point.
Although I’ve never see it written as “Red Worms will double in biomass in 90 days” (all versions I’ve ever seen either refer to numbers or simply a doubling of “population” which I guess could be interpreted either way), that’s still something that would be really interesting to test out! With my own “4 Worm Reproduction Experiment”, the vast majority of worms were indeed juveniles when I did my final count.

I have been composting leaves here in Michigan for many years. My yard yields around 30, 350 lb. loads of mulched leaves a year. They compost fairly quickly, so I am sure the worms are eating well.

The problem is that I can’t find the worms, no matter if I dig in the leaves, under them or in the soil under them,(which is the casings of the worms, black and rich). Where are the worms?

@Donald, ‘incubating worm eggs’ is actually nothing more than keeping them in their original vermicast and keeping the vermicast moist. They will hatch from themselves. Shipping them from a foreign country has its risks though. Radiation and wild tempratures are an example.

Hi interesting facts. I’ve only just started my worm farms just over 6 months ago. I first started with 1000 worms and had 5 100mm drainage pipes about 600mm long. I drilled many holes about 10mm all the way around and from bottom to top. I dug these into my new garden with the top sticking out and covered with a paving brick. I added about 200 worms to each and started adding our kitchen scraps. After six months I pulled them out and transferred them to my 120l worm farm bin. Only got about 2000 worms but I am sure there would be more still in the garden. About 6 weeks later my bin is full of worms. And the worms are back in the pipes in the garden. I have a second bin ready to start and will use the worms from the garden to start it off again soon. Any worms that go back into the garden with the compost will end up back in the worm farm from the pipes. A great hobby and good way to save money on fertilisers and mulch.

My first attempt with red wrigglers about 15 months ago. I was doing good then I got alot of rain. I had 2 broccoli boxes with about 500 worms in both which i got about 50 kilo of casting out of. Then new bedding and kitchen scraps. Then alot of rain and very windy. My boxes flooded left with couple of worms and eggs. Which I kept over winter in garage. Started again spring time. I put a large pot of cow manure in the vegatable garden left it for about 6 to 7 weeks. Then went to use cow manure there was worms all through it. So I made a 25 gallon flow through bin. Also check on a few horse studs in my area found 2 horse studs with manure piles from cleaning out the stables. This is after checking on about 10 different horse stud farms. Some farms have there manure truck away every week in skip bins. Other farms to dry manure piles. Now I have about 4 to 5000 worms and 2× 25 gallon flow throughs and just build a 35 gallon flow through. Still using the large pot of cow manure which I just harvested about 40 pound of casting and about 200 eggs and 1000 worms I left a couple 100 worms in pot added new aged cow , horse manure and saw dust, straw . Where I think I will harvest early march. If I don’t have enough kitchen scraps I use horse and cow manure mix with straw , sawdust and composted leaves. I am trying to grow the worms in corner of backyard use to be compost pile for years a lot of garden worms. I will see if red wrigglers grow there as well in a 3′ by 2′ patch lot of manures and leaf litter away from vermicompost bins, only worry some direct sunlight. But should be ok. The Horse studs where I got my red wrigglers there was a lot of sun light. At times all my bins have had problems ants, one day last week I check on the worms with my hand turn over little bit hand and arm brown mites every where. To much moisture so I added dry straw and garden lime mix it in. Couple days later all ok. Temperature here in the 30′s alot.
My question is what are bright yellow eggs about 5 to 6 mm . I know there not worm eggs. Red wrigglers are olive yellow turning brownish yellow before they hatch about 2 to 3mm

What happens when you have too many worms per bin? Also, any idea what is going on when you see a handful size clump of mature looking worms? Is this a worm turf war? Or lovemaking? I am also curious, so far I have heard that you should not release the Red Wiggler worms into the wild garden – is that true? Why?
Thank-you!

Any ideas how to get rid of flies and other creep crawlers in my worm bin? I don’t want to bring it into my house like that

To keep out these pests, flies, & creep crawlers, ants etc you can try sprinkling a little bit of turmeric powder, may be even Neem leaves, or Neem oil after mixing diluting with water & spray it. What ever you do don’t spray pesticides.
