Separation is the key to keep your Mealworms Healthy and Productive
Separation is the key to a successful mealworm colony. Remember to prevent cannibalism you need to:
- Keep large mealworms separate from small mealworms (optional but recommended)
- Keep beetles separate from everything; eggs, mealworms of all sizes and pupa.
Rotating Mealworms with These Easy Steps…
- Place your mealworms into the first container (Containers 1) until the pupas appear.
- Pick out the pupas and place them into the egg cartons of Container 2. The beetles will crawl out of the egg cartons into the mealworm substrate below and lay their eggs.
- Every few weeks move both the pupa and beetles from Container 2 to a new container (Container 3, then container 4). The eggs left behind in Container 2 will start the next generation.
- Once you have used up all the mealworms in Container 1, keep rotating things through. If you need more mealworms simply add more containers.
- As described earlier the eggs are laid in the mealworm substrate. In this case “the gold is in the poo”, so don’t throw is out if you need more mealworms.
- It takes around 2 weeks for the beetles to mate and lay their first eggs, but after this period you can move the beetles and pupa to another container every few weeks or so.
- In this way you can create as many containers of mealworms as you require and importantly you separate beetles from other life stages and the mealworms will be of a similar size.
- To begin with keep a record of how often you rotate them through and how many containers you are using. Eventually you will know how many containers you need to maintain supply and how frequently to move the beetles to the next container.
- In container 2, the pupa can be separated from the beetles by placing them into an egg carton which is placed on top of the substrate. When they turn to beetles they will climb out and find their way to the mealworm substrate.
- If beetles are getting into the egg cartons from the substrate, you can raise them up using blocks or tape them to the side of the container. Some people like to have separate containers for pupa and beetles but this would require you to constantly inspecting and moving the beetles across to their container.

How do you manage a mealworm farm? ›
Mealworm Farm Maintenance
Once or twice a week, give them a piece of carrot or slice of potato for hydration. During this time, check the colony or drawers for any pupae or beetles. If you have a tiered system, move beetles to the Beetle Bin, and move any pupae to the Pupae Tray.
The mealworm is actually an insect that undergoes complete metamorphosis. It is not a worm at all. Mealworms are the larvae of “darkling” beetles. They have four life stages: egg, larva, pupa, adult.What is the easiest way to breed mealworms? ›
- Punch small holes in the lid for ventilation, place a layer of old hessian sacking in the bottom and sprinkle fairly thickly with bran. ...
- Introduce two or three hundred mealworms into the prepared tin. ...
- The beetles will lay eggs which hatch into mealworms and so on.
Step 2: Prepare The Container
Note: The ideal temperature to grow mealworms in is between 77 – 81 degrees Fahrenheit. Mealworms do reproduce in temperatures ranging from 65 – 100 degrees Fahrenheit, but temperatures above 86 degrees and below 62 degrees may negatively impact growth.
Keep them refrigerated
The simplest solution is keep them in a refrigerator. The mealworms prefer temperatures around 70 degrees, but you don't. At 70 degrees, this encourages the mealworms to consume rapidly, which then causes them to transition into the darkling beetle.
Light: Consistent with the name darkling beetle, they prefer the dark. Keep the container out of direct sunlight. However, one source indicated that if mealworms develop faster when provided with light.What conditions do mealworms prefer? ›
Habitat: Where Do Mealworms Live? Their normal habitat is dark, cool and moist locations where there is suitable food and sheltered areas such as under rocks, logs, in animal waste accumulations and in moist, stored grain storage areas.Why are my mealworms turning black? ›
When pupae die and turn black, it's usually because the worms weren't given enough moisture with carrots or potatoes at the end of the larval stage. They need to store the moisture to last through pupation and will dehydrate and die if they didn't get enough. They are also very heat sensitive.How long do mealworms take to breed? ›
MAINTAINING YOUR COLONY:
The mealworms, which are the larvae of the darkling beetle, will need 3 months or more to go through their life cycle and reproduce to make new mealworms.
Warmth speeds up the life cycle process, so your mealworms will pupate faster if they are kept warm.
What is the life cycle of a breeding mealworm? ›
- Mealworm beetles go through four distinct stages of development: egg, larva, pupa, and adult. ...
- Mealworms remain larvae until temperatures drop, when they transform into pupae to hibernate. ...
- Yellow mealworm larvae and adults constitute a variety of concerns for homeowners and grain producers.
Beetles will mate and begin laying eggs within a few weeks. Eggs can hatch in just under a week, again, if temps and humidity are right. Every few weeks, sift out the small particles from your mealworm colony and you will end up with eggs and frass.What is too hot for mealworms? ›
Ideal temperatures are 25-28 oC (77-82 oF) degrees for yellow mealworms, however their productivity will greatly reduce below or above these ranges. The reproductive stages (pupa and beetles) are prone to high death rates at higher temperatures. Moderate growth rates is achieved at 20-25 oC (68-77 oF).How long do dead mealworms last? ›
If you must store them in a cabinet, make sure that the cabinet is both dark and cool. Place the mealworms into either a plastic or glass container with a tight-fitting lid. They will last up to 6 months with no degradation.How long do mealworms stay mealworms? ›
Tiny mealworms emerge from the eggs -- darkling beetles in the larval stage. The larvae spend all of their time eating and growing. The mealworm stage usually lasts about 10 weeks.Do mealworms need water to live? ›
Mealworms are able to absorb water from the air through their skin and they make metabolic water as they digest their food, but mealworms do much better if supplied a water source. Some common water sources used are carrots, apples, and potatoes.What kind of oatmeal for mealworms? ›
Our go-to preference is typically instant oats or quick-cook oatmeal, and we try to avoid steel-cut oats despite their protein & fiber content because they're a little too tough for our insect friends to bite into. Alternatively, wheat bran or bread crumbs are always a fine option.What size mesh for mealworm farm? ›
A sieve with a mesh size of about 1.5-2 mm will sort leftovers of feed as well feces from the larvae. If you use a piece with a mesh size of 4 mm, you will keep the largest lumps of feed while the larvae will fall through.Do mealworms like coffee grounds? ›
– Composting Friend – Feed your mealworms rolled oats and peelings, coffee grounds and salad. Both you and your mealworms will be happy subsisting on a similar diet.Do mealworms like orange peels? ›
Mealworms posses a mighty appetite, and prefer to not be limited to the blandness of wheat bran. Go ahead and get a little wild, throw in some thrilling potatoes or some outrageous orange rinds, and check on them a few days later. Be amazed at the herbivorous power of the voracious mealworms!
Why do mealworms have to be cold? ›
The cooler temperatures will delay the process of metamorphosis, which stops them from continuing their life cycle and turning into beetles. Therefore, store your container of mealworms in your refrigerator (at 45-50 degrees F), this will cause them to go into a dormant state and be usable for feeding for 6-10 weeks.What kills mealworms? ›
Those bothered by mealworms should remember never to discard infested food without first killing the insects. This is best done by placing the infested food in a container and heating it in an oven at 130° F to 150 °F for 30 minutes.How can you tell if a mealworm is male or female? ›
On the underside of the rear end of the beetle there are segments of the body. The plates of these segments are called sternites. In the female there is little or no separation between the three most posterior sternites while in the male the intersegmental membranes are clearly visible with a lighter coloring.How often should you change mealworm bedding? ›
Mealworms will need at least a couple inches of bedding but it does not have to be deep. After your colony is established you will want to change the bedding out when needed. I change mine about every 3 months, but you may find the need to change it more or less often.What diseases do mealworms carry? ›
Lesser mealworms readily feed on dead and dying birds. They can become contaminated with pathogens such as Salmonella, Escherichia coli, or infectious bursal disease virus.Why is my mealworm curling up? ›
Pupa (Stage 3)
The mealworm larvae will appear to curl up and harden. You would be forgiven for mistaking them for dead but fear not, this is all part of their lifecycle. They will be pretty inactive at this stage, but when you pick them up they should wriggle.
Mealworms like to eat apples and other fruits, potatoes, oats and grains, and birdseed. Wild mealworms also eat decaying matter like fungus, dead leaves, rotting fruits and vegetables, and rotting plants.Can you overfeed mealworms? ›
It's important to note that mealworms do not provide complete nutrition and should be used only as a supplemental food source, offered on a limited basis. Overfeeding can cause health issues for adults and young!”Do mealworms prefer wet or dry? ›
In conclusion, mealworms prefer cold, dry, low elevated environments.How often do mealworms reproduce? ›
The mealworms, which are the larvae of the darkling beetle, will need 10 or more weeks to go through their life cycle and reproduce to make new mealworms. They will change from larvae to pupae, then from pupae to mature beetles. The beetles will copulate and lay eggs in the substrate, which hatch 1 to 4 weeks later.
How long does it take for mealworms to turn into eggs? ›
The female darkling beetle lays hundreds of tiny, white, oval eggs, which hatch into tiny mealworms (the larval stage) - it takes from 4 to 19 days to hatch. Each mealworm eats a tremendous amount and grows a lot, molting (shedding its exoskeleton) many times as it grows.How long does it take for mealworms to lay eggs? ›
Eggs. It takes approximately two weeks for the adult beetle to mate and lay eggs after it emerges from the pupae (cocoon). Each female beetle can lay 100-200 eggs at a time and up to 500 over their life. Eggs are laid to any surface which may be substrate, container bottom or egg cartons.What kills grain mites? ›
Flour mites and their eggs are killed by contact with hot, soapy water. Once all pantry items are cleared out, use a rag with hot soapy water to thoroughly wipe down all pantry surfaces.What temperature kills grain mites? ›
“Controlling grain temperature is critical for maintaining grain quality,” says North Dakota State University engineer Ken Hellevang. “Insect reproduction is reduced below about 70°F., insects are dormant below about 50°F., and insects are killed if grain is below 30°F.What are the little white bugs in my mealworms? ›
One of the worst things that can happen to a mealworm farm is an infestation of grain mites. These tiny white creatures will be obvious when they swarm by the millions up and out of your worm trays.What substrate is best for mealworms? ›
A mealworm substrate can be made from ground up cereals or meals (grain and seeds). Common meals include; wheat, oats or corn. Other alternatives include wholegrain cereals or course flours. You can also provide them with small quantities of whole meal bread and biscuits.Do baby mealworms need water? ›
Use moist foods to provide the worms with water.
Don't put any water in the container. Mealworms will crawl into a water dish and end up drowning. Use the fruit and vegetables as a source of moisture and water. Switch out dried or molded pieces of fruit and vegetables for fresh ones as needed.
Allow the mealworms to stay at room temperature for about 24 hours. This will allow them enough time to “wake up” and become more active so that they can consume food and water. The mealworm bedding is their food source.Do mealworms like wet? ›
Moisture and Relative Humidity: Mealworms do require moisture. Too little moisture slows growth and reduces size. Too much can produce mold. If larvae are provided with dry food, they can survive and produce one generation a year.Can mealworms crawl out of dish? ›
They all can crawl out. Q: Why does this look different than the one I saw in the store? It looks rougher and not smo… A: It's not a water dish so its not smooth, it has a lip for containing the mealworms for you…
How do you care for a mealworm colony? ›
MAINTAINING YOUR COLONY:
While you wait for this process to take place, check the bin every day and take care of the mealworms by regulating the temperature, removing and discarding any dead mealworms or beetles and changing out the food. Getting a second container is essential a few weeks into the process.
Habitat: Where Do Mealworms Live? Their normal habitat is dark, cool and moist locations where there is suitable food and sheltered areas such as under rocks, logs, in animal waste accumulations and in moist, stored grain storage areas.Can I use oatmeal for mealworm bedding? ›
Mealworms are a natural pest of grains, so they will readily feed on the wheat bran and rolled oats used for the bedding.What is the life cycle of mealworms? ›
Life Cycle Stages
Mealworm beetles go through four distinct stages of development: egg, larva, pupa, and adult. The amount of time it takes the insects to go through these stages depends on the temperature of their environment and availability of food.
- Add about 3 or 4 inches of wheat bran to a plastic box or a small fish tank. ...
- Add some pieces of fresh fruit or vegetables as food and to supply moisture. ...
- Secure a piece of cheesecloth over the tank with a large elastic band. ...
- Place the habitat in a warm room.
On average it takes approximately 10-12 weeks (3-4 months) for a mealworm to go from egg to adult size. The beetle stage will go for another 8-12 weeks (2-3 months).Do mealworms like light or dark better? ›
Light: Consistent with the name darkling beetle, they prefer the dark. Keep the container out of direct sunlight. However, one source indicated that if mealworms develop faster when provided with light.What are the tiny white bugs in my mealworm farm? ›
One of the worst things that can happen to a mealworm farm is an infestation of grain mites. These tiny white creatures will be obvious when they swarm by the millions up and out of your worm trays.How do you get rid of grain mites without killing mealworms? ›
When you get your bran or grain for your colony, you can bake it in the oven at 175° F for about 20 minutes to kill the mites. Let it cool completely before adding worms to it. The mites thrive in moist, warm conditions; so it's a good idea to leave your bins open and not put lids on them.
