Silkworms
89Raising Silkworms
Silkworms are a great staple feeder for your reptile. They are packed with nutrients. They have no smell, can't jumb or run away, cannot bite, and are slow moving. They are one of the better feeders for your pet.
Silkworms can be a great feeder, but of all the feeder insects, they are hardest to breed. But, it's not impossilbe to accomplish.
Materials Needed to Breed Silkworms
- Plastic containers
- Wire or toilet paper roll for worms to cocoon
- Incubator
- Petri dishes
- Silkworm Chow Silkworm
Basic Silkworm Setup
Since silkworms do not drink water, they get their needed moisture from the food they eat, you will need a covered container to raise them in. The container should be almost air-tigt to prevent the food from drying out, but have small holes to allow air exchange.
Add the toilet paper roll for the silkworms to climb and cocoon on.
Add food, either a commercial made silkworm chow or mulberry leaves. Silkworms eat 24/7, so food must be constantly provided in the container.
A good temperature to keep silkworms would range from 78-88 degrees F.
Breeding Silkworms
Raising and keeping silkworms alive is one thing, but breeding is another story.
Silkworms will spin a cocoon about 28 days from the time they hatched if they are raised at approximately 85 degrees, fed, and maintained regularly. Place a piece of paper or a paper towel on the bottom of the container, so that when the moths emerge and are ready to lay eggs, the paper can be removed with the eggs, easily.
Once the moths emerge, they will mate. (Females are significantly larger than male moths.) They stay mated for about a day, and after separation, the female lays eggs, while the male looks for another female to mate with.
Sometimes another male will grab the female before she can lay eggs.
Each female will lay between 200 - 500 golden yellow eggs! Put paper on the bottom of the container and remove empty cocoons as the moths emerge. The moths will lay eggs on the paper.
When first laid, all eggs are lemon-yellow. After three days, they will turn white if they are infertile, or turn black if they are fertile. Fertile eggs usually hatch about two weeks after being laid in the middle of the summer, but they usually won't hatch unless subjected to "winter" in your refrigerator for at least several weeks.
Wait until the eggs turn black before putting them in the Ziplock bag in the refrigerator. Once you take eggs out of the fridge, they will hatch in about 7-20 days. Direct sunlight in the morning for a few hours quickens the hatching process.
To incubate the eggs, place about 200 of them on a petri dish. Keep the eggs between 78 and 88 degrees F. An incubator works best at keeping the temperatures stable. The eggs can hatch at room temperature, but will take longer.
Place a damp paper towel next to the petri dish to keep the humidity levels high. Once the eggs have turned from a purplish color to a light bluish/gray, shows signs that they should hatch within a couple of days.
When the eggs begin to hatch, prepare silkworm chow, and place it in the refrigerator to it will be ready. Once they start to hatch, place small bits of chow in the petri dish, so the emerging worms will have something to munch on. Remember silkworms eat constantly, so always provide food. Try not to let the chow touch the unhatched eggs.
It is better to keep the young silkworms in the incubator to better assure their survival rates. After about 8 to 12 days, you can remove the worms from the petri dish, and place them into a small plastic container.
Remember to clean the container to prevent mold. Mold develops from high temperatures and high humidity. If the worms are covered too long, mold can develop and may kill the worms. If mold develops, grate about 1/2 inch of chow all over the worms with a cheese grater. Several hours later, as the worms crawl to the top of the new chow pile you can peal and lift them off the moldy chow and place them into a new container.
** Remember to always provide the silkworms, of all ages, with food, either chow or mulberry leaves. Remember that young silkworms have weak jaws, so if you are using Mulberry leaves, provide only the smallest, newly grown leaves.

Ouhhh!!! yuck, grouse , like totally disgusting!
Cool videos !
This is more of a question and if anyone knows the answer, please answer! I am hatching silkworms for the first time ever and i think they are getting close to hatching but my question is how can you tell when they are hatched they are pretty small so can you see them moving around? I want to make sure to give them food so they don't starve. Please help! Thanks.
You should be able to see them moving around. I am not 100%, as I've never successfully hactched silkworms. But, at the slightest movement, definately provide just a little bit of food.
i cant find malbruy leaves is there any thing else thay can eat
Not really. You can buy silkworm mix that you mix with water.
To me these silkworms don't look very appetizing...
amazing videos.........
Whitney05, You are awesome! I want to raise silkworms. My best friend and I are doing an Animal Club. I have to raise Silkworms! I don't have anything to do it with. HELP!
What do you need help with?
Ah, brings back memories. I used to raise silk worms every year as a child, from the time I was about 4 to the time I was 8 or so.
i have to do a project for my school so i need some help seraching about silkworms but i have to write it in my own way please help me
What do you need help with exactly?
Hi I have like 800 worms and they wont breed I have had them for a week and no breeding.Your page directions made 6 silkworms breed and thats it.but your info is helpful.
Are the worms fully maured? You may consider raising the temps just a few degrees to induce the silkworms to coccoon.
Quick question, does anyone know if the eggs stick to the surface they are first placed on, im afraid that if im not around they will either lay them on a towel covered with the fluid they release when they hatch from their coccoon or they will lay the eggs on the bottom and i wont be able to move them
2Questions I have to ask.
When did silkworms become so popular?
Have any of you silkworms farmers ever spun any silk?
:-)
Another well written post - don't know why I read it but It was fun.
They've been pretty popular for the reptile community for several years now.
I'm not a silkworm farmer, so I wouldn't know about that one. ;-)
Silkworms became popular like 3 months ago.
They've actually been popular for several years...
Can I hatch silkworm eggs from a shoebox cuz thats what my next door nabour does and it does not work for me and i do exactly what he does.
for best results use an incubator. He may have the shoebox at more stable and warmer temps.
18 YEARS AGO I had a 5th grade teacher who every year had them as a class project and many of us my self included took them home as pets and loved raising them.
Hey, how do you go about incubating the eggs? I believe they have to be glued down for some reason? what's the process of getting them in an incubator after moving them from the place they were layed? What should the eggs even be layed on?
thanks in advance!
-Big John Ster
Typically they are incubated in an incubator, such as a hovabator incubator. You should be able to just remove them.
one of my silkworms didnt spin its cocoon and has gone a dark yellow colour.what will happen to it?
how do you tell the diff between male and female??
can silkworms eat mulberry berrys i have been feeding mine them and they eat them so igust want to no if they do.is it bad for them.
I would stick with just the leaves.
Hi,
I'm trying to buy some silkworms for my kids to raise as pets, can you recommend any place that I can order from?
Thank you!
try mulberryfarms other than that, i'm not sure.
how can u tell if a silkworm is male or female?
You can't tell until they're moths.
This is really fascinating. I should try this for my iguana. Where can you get mulberry leaves if you don't know where to find the trees?
You can check out a few websites online. they offer a powdered mulberry mix that you mix with water (if i remember correctly). You can use that instead of actual leaves.
Silkworms are extinct in the wild annd are fully domesticated.They cannot fly unlike their wild,now extinct ancestors.Great hub.
secretscp, you shouldn't be feeding your iguana protein though! tsk tsk.
u Can tel the male and the female apart the one with stripes is male
We raise silkworms as part of our science unit in first grade. I have a ton of eggs...would anyone like them?
Read the book Project mulberry very informative
Just brought home silkworms from my sons class.. also have some of the "chow" they had at the school that was already made.. hoping they cocoon before I run out of it lol. Do you have to seperate them from a food source before they will do so? or will they do it even with food around?
They'll coccoon around the food.
