Enclosure

To make your own enclosure all you need is…

  1. Sterilite 6Qt (5.7 L) Tupperware container
  2. Screen
  3. (Choose one, a few, or all) Wheat bran, oatmeal, cornmeal, wheat flour, Wheaties, Cheerios, ground up dry dog food, or a mixture of these dry foods.
  4. Scissors
  5. Hot Glue Gun

Get your sterilite 6Qt (5.6 L) Tupperwear container and cut a big hole in the lid of the container. Then hot glue a piece of screen that you cut out to cover the hole in the lid. This will allow for proper ventilation in your worm enclosure. Next, place about 3-4 inches of food/bedding into the tupperwear along with your worms. Lastly put a piece of fruit or  vegetation in the tupperwear and place the lid on the enclosure. Then you are done.

 

Most of the time, the worms are unable to get out of the tupperwear depending on how much food/bedding you put in. The smooth surfaces of the tub are too slick for the worms to climb. So a lid isn’t even necessary.

Furnishing

No furnishing is needed.

Lighting and Heating

Mealworms and Superworms do not need any special lighting whatsoever. The only thing they need is a source of heat through a normal house bulb or heat lamp. You may even use a heating pad.

Temperatures should be…

Day Time

70 – 80 °F is recommended.

Night Time

No lights are necessary. 65 – 75 °F is recommended. If it is too cold to achieve this temperature without lights, I recommend using a heat emitter or a reptile infrared heat light. Make sure to check temps at night, to reassure the temps are good to avoid stress.

Feeding

Your mealworms and superworms will get their food through their bedding that you choose to put in their enclosure which may include…. wheat bran, oatmeal, cornmeal, wheat flour, Wheaties, Cheerios, ground up dry dog food, or a mixture of these dry foods.

Humidity and Hydration

Humidity should be low (almost dry). Too much humidity will most likely wipe out your colony of worms. Humidity builds up bacteria and mold in a worms enclosure.

 

Hydration will be given to your worms through a source of fresh fruit and vegetables. A good source of hydration would be apples, carrots, slices of potatoes, pieces of kale, and etc. Make sure to remove pieces of uneaten fruit and vegetation every other day or weekly to avoid mold build up in the enclosure. Do not use a bowl of water since worms will crawl in and drown.

Substrate

Their substrate will be their food which will be… wheat bran, oatmeal, cornmeal, wheat flour, Wheaties, Cheerios, ground up dry dog food, or a mixture of these dry foods.
