Mealworms look a little like worms, but they are not actually worms at all -- they are darkling beetle (Tenebrio molitor) larvae. Golden yellow and divided into 12 segments, mealworms are a rich source of protein, vitamins and calcium for birds, according to the Cornell Lab of Ornithology website. Pet stores and online retailers sell packaged live mealworms, and you can store them at home in plastic containers such as ice cream buckets.
Mealworms take up to three months to develop into beetles when stored in a cool, dark area of the home. The packaging mealworms arrive in isn't suitable for storing them. You should pour them into another container, where they can live for several weeks with food and a source of moisture.
When transferring the mealworms to a container, place a piece of white paper underneath the container to see any that escape. Alternatively, put the container outside before adding the mealworms.
Items you will need
Dry oatmeal, wheat bran, chicken mash or cornmeal
2- to 5-gallon plastic container with sealing perforated lid
A chunk of raw potato, apple, carrot or a banana peel
Spread a layer of dry oatmeal, wheat bran, chicken mash or cornmeal 1 inch deep over the bottom of a 2- to 5-gallon plastic container.
Place a chunk of raw potato, apple or carrot or a banana peel on the grain.
Pour the packaged mealworms into the container.
Cover the container with a secure, perforated lid. Poke tiny holes in the lid if necessary.
Place the container in a dark place at temperatures below 80 degrees Fahrenheit. The North American Bluebird Society explains that the speed at which mealworms develop into beetles is affected by temperature. Low temperatures slow mealworm development.
Replace the piece of potato or other vegetable or fruit when it becomes moldy or smells offensive.
In a refrigerator, mealworm life cycles slowand they can be stored for several months. Store mealworms for the long term in plastic containers with a 1-inch layer of grain. Don't add any vegetable or fruit pieces. Cover the container with a lid that allows air to pass through. Label the container and place it in a corner of the refrigerator.
