Let me begin that many websites offering information, not just African nightcrawlers but other worms as well, do not even raise worms. Rather, they simply use a drop ship company or companies to fill and ship all of their customer orders. That being said, I personally raise red wigglers, African nightcrawlers, European nightcrawlers, Alabama Jumpers and Mealworms. I also have two dogs

Why would some websites state that you can raise African nightcrawlers in colder temperatures? Your guess is as good as mine however many probably due to lack of knowledge and experience. I have seen a number of websites which have literally copied and pasted, word for word from other websites.

Rather than me simply restating what I have before, which is in direct conflict with some other websites, I figured I would prove it to you so as there would be no question in your mind. I decided to run an experiment which by the way I had informed a friend would only last 24 hours due to my experience in raising worms. After all, as the saying goes, a picture is worth a thousand words.

Now before I proceed, let me inform you that the last picture is kind of graphic which may not be suitable for some…

That being said, I decided to use a refrigerator which I store mealworms prior to shipping which is set at a constant 48 degrees Fahrenheit. Now mind you, I only used four good and healthy 6 – 8 inch African nightcrawler worms since I did not wish to waste a bunch, which by the way I hated to part with

You can see the four worms in the bait cup, which I then placed some castings which were straight from the original bin I had pulled the four worms from. You will notice the worms look in great shape. I proceeded to place the African nightcrawlers into the refrigerator at 7:48pm January 1, 2010.

Now for any skeptics out there, I used my automotive multimeter which also has a built in thermometer that I now use full time on my worm bins as it is easy to read the temperature especially when your eyes begin to deteriorate as mine have. As you can see when I placed the sensor on the end of the wire inside the refrigerator with the door shut, the reading was at 48 degrees Fahrenheit.

I checked on the worms 12 hours later and they were already just about dead as they had begun to discolor turning a pale white towards the tail ends. Basically the circulation to the tail end of the worms has either stopped or slowed considerably. Mind you twelve hours is basically the time for an overnight temperature. At this point, even if the temperatures had risen up to the eighties, these four worms would not have made it as they were already too far gone.

I did not get a picture of this stage as I found out the batteries in the camera had run too low, hence I placed them on the charger.

I had some running to do this evening, January 2, 2010, hence I checked on the worms a little later than I had anticipated. I pulled the worms out of the refrigerator at 8:29pm just about 24 hours and 49 minutes since the experiment had begun.

As you can see from the picture below, the African nightcrawlers are dead. The pale white color has spread throughout their bodies while a bulging red color separates the paler areas. These worms are not only dead but have been for a while since they are now beginning to decompose.

One major item to notice is the fact that all four worms are the same. In other words, the temperature did not affect 25% or 50% but rather 100% of the worms!

Even if you tried to raise African nightcrawlers at 60 degrees Fahrenheit they would die, most likely surviving up to a week before keeling over, however the end result would be the same.

This is mainly why I state the African nightcrawler needs 70 degrees minimum. In fact, this is the low end of the spectrum. If you really want your Africana nightcrawlers become active and prolific, get the internal worm bin temperature up to 80 – 85 degrees Fahrenheit, which is what they prefer!

I hope this helps to clarify first the temperature range by which you want to raise your African nightcrawlers and secondly that I will not throw you a bunch of misinformation, but rather facts from my years of experience in raising worms.

Now go and tuck your worms in for the night to keep them warm

For example, if your worm bin internal temperature is at 60 degrees Fahrenheit your worms will be less active, hence eating less food. This is also a reason I do not recommend refrigerating red wiggler worms, African nightcrawlers, European nightcrawlers or Alabama Jumpers. As they become less active and eat less they begin to get thinner and leaner, which is not what fishermen and women want.

Moisture and pH levels will also affect your worms and how much they will eat.

Red wigglers can eat half their body weight per day in decomposed food scraps, shredded paper products… under the correct conditions. So one pound of red wiggler composting worms can eat half a pound of food a day under ideal conditions in a homeowner style worm bin. In a larger style bin, 32 square foot continuous flow system for instance, under ideal conditions; red wigglers have been known to consume more food per day.

Now your African nightcrawlers and Alabama Jumpers are probably your most ferocious eaters. The ones on our farm indoors are fed daily under ideal conditions. Now I do not feed these guys food scraps but have shifted to Purina Worm Chow as their main diet. I do not have to run out constantly to pick up scraps and manure from local vendors some of which is smells pretty bad. African nightcrawlers are not as big a composting worm as the red wiggler on food scraps; however are excellent manure worm. I do not recommend chicken manure, however rabbit manure is superb as it does not require the process of heating. Horse or cow manure is also excellent however be sure the manure has been heated prior and that the animals have not been on de-wormer.

Now grain mix differs from food scraps as you do not want to feed your worms ½ a pound of Worm Chow per one pound of worms. You simply sprinkle on the surface area and do not mix in or the bin will become sour and begin to kill off your worms. Not only do the African nightcrawlers devour the chow, but damp shredded newspaper which we keep on the surface area and replace as needed. This ends up turning into the dark, rich worm castings known as “Black Gold”.

European nightcrawlers one of the favorite worms by those that fish, are also another good manure worm and are not as great on food scraps as the red wiggler. They also do not have the ferocious appetite as the African nightcrawler. I feed them with the grain mix by Purina, however anywhere from once every day or two while maintaining less feed in each bin compared to the African nightcrawler. The European nightcrawler bin is probably the easiest to sour by adding too much food. Do not expect these worms to eat as much, however they are extremely prolific and do produce a nice worm castings.

This should give you a good basis as where to begin feeding your worms, however keep in mind the conditions of your worm bin due play a large role in how much to feed your worms.

African Nightcrawlers are raised by some just for the castings. The African Nightcrawlers worm castings are darker in color and fluffier than other composting worms. There is no difference in the microbes or quality of the worm castings other than the looks and feel.

The macro photograph below does not really do the worm castings justice; however you can make out the African Nightcrawlers castings on the left, which are darker. The worm castings on the right are red wiggler worm castings.

Both worms were fed the same diet and were raised in the same bedding materials.

Some worm farms and brokers sell African Nightcrawlers in counts of 600 to 1,200 per pound. These are bed run, usually very small African Nightcrawlers which are still good for composting; however do not make a very good fishing worm as many are the same size as red wigglers at these counts.

Many others offer a 200 to 300 count per pound African Nightcrawlers. These are approximately eight month old worms which run about 6 to 7 inches in length without being stretched out. These make an excellent fishing worm in the warmer weather as African Nightcrawlers are a more heat tolerant worm.

Organic Worm Farm offers the latter, 200 to 300 count per pound as well as the super large African Nightcrawlers, 180 to 225 count per pound! These monsters are approximately 10 months old and run up to 10 inches before being stretched out. If you are looking for the largest, active worm to fish with, these are the worms you want. The Canadian Nightcrawler will run larger, however is not nearly as active as the African Nightcrawlers.

The below photo shows an average 200 to 300 count African Nightcrawler on top with the super large African Nightcrawler, 180 to 225 count per pound below it.

The monster, super large African Nightcrawlers were raised by feeding them Purina Worm Chow. It is a food formulated especially for worms which is fortified not only with grains but minerals and vitamins as well. To raise the largest, fattest worms as well as the most prolific worms, there is nothing that beats using Purina Worm Chow as either a diet supplement or as a sole diet for worms.

Now there are more extravagant formulas, one which will be available online in the near future, however if you are anxious to try something the following will prove beneficial.

First, I feed my worms what my mother fed me that she claims made me so tall, greens! I do mix them up and limit starches such as bread and potatoes. I also refrain from using tomatoes and other high acidic fruits and vegetables.

I realize other sites will tell you that worms love coffee grinds, and they do, however if you add too much your bin will end up becoming acidic. Just as most of us were told growing up, anything is good in moderation.

For my trophy worms I use for fishing, I actually use a blender to liquefy the ingredients. Afterwards I mix in a little spent coffee grinds as well as peat moss to thicken the mixture. Now don’t go making it like a thick mud but rather just enough to keep the liquid from running off or ponding in your mix. Remember to allow it to sit in your garage or outside covered up for about 24 hours as the peat moss will continue to draw up the moisture.

Now one thing I do for the trophy worms is to freeze my mix as this modifies the molecular structure enabling the mix to break down even faster for quick consumption by the worms when I do feed them. Just be sure to thaw it out and warm up to room temperature before adding to your bin.

The Simplest Advanced Grain Formula Mix You Can Make:

As with any grain mix, sprinkle on top and even mist with some water. I personally leave my fishing worm bins uncovered; hence I place some moist shredded newspaper over my grain. Be consistent on feeding the grain as needed whether once a day or once every couple days.

The recipe:

2 Cups Oatmeal

1 Cup Cornmeal

1 Dozen Egg Shells

Many websites state you need to cook your eggs with the shells in order to use in your worm bin. I have never had an issue by rinsing cracked egg shells than have not been cooked with warm water thoroughly. Allow them to dry out well.

Add the egg shells to you blender and pulverize them to a powdery mix. Slowly add your other ingredients. You may need to shake the blender or rattle it back and forth as this is a dry mixture in order to continue mixing and breaking down to a powdery mix.

There are other formulas which will enable faster growth, without hormone shots which I will introduce in a couple weeks.

First the African nightcrawler is probably one of the most heat tolerant worms around. They like temperatures around 75 – 80 degrees Fahrenheit. These are also a very large worm with mature adults reaching 6 – 8 inches in length.

African Nightcrawlers are definitely the super red worm for fishing, especially in the hot summer months when water temperatures peak, hence killing off other worms much quicker.

One area that is overlooked when it comes to the African nightcrawler is the fact that it eats more food than other red worms, including red wigglers and European nightcrawlers.

I have seen numerous sites state that red wrigglers are the best composting worm.

Since many people do not raise African nightcrawlers, perhaps they are just repeating what they have heard online posted by others; which in reality is the way the Internet works sadly. One person states something and others basically plagiarize what they read

Being I have raised these super red worms for a while along with red wigglers and European nightcrawlers, I can tell you from personal experience there is no comparison between the African nightcrawler and red wiggler. The African nightcrawler wins hands down.

Below is a picture of a new African nightcrawler bin I setup just three weeks ago.

I cleared to the bottom of the bin, only to expose 3″ of mostly worm castings, not vermiculture. My last bin was setup only for a month and a half and after screening yielded a full 5 gallon bucket of worm castings. Keep in mind this is a 30 gallon bin whereas most people use an 18 gallon bin.

As another comparison, I did the best I could as the nightcrawlers were camera shy

The African nightcrawler just stretched all the way out and sat there while the European nightcrawler wanted to curl up.

The photo below is of a 4″ or so European nightcrawler and as you can see the African easily surpasses this by about twice the length, although he looks lean from being stretched out on a paper plate .

Here is a snap shot of an African nightcrawler. To give some comparison, I used to play basketball and easily could palm the ball

In conclusion, if you are looking for a heat tolerant red worm which in my experience, by far the best composting worm all in one, try setting up an African nightcrawler worm bin.

In order to make this easy and cost effective, I am offering a ¼ lb starter package shipped priority mail. Click here for more information on how to obtain these super red worms!

Happy Worming,
