Q: [header] How to care for mealworms [title] Keep the mealworms in a glass, metal, plastic or wax coated container. [step] You want to be sure they can't get a grip on the sides of the container you keep them in, as they could likely climb out. Containers with smooth, slippery sides and surfaces are best for keeping the mealworms inside. <sep> (A) Be sure to try to wash and disinfect the container in water between uses. [substeps] Remember you may want to use bleach when treating a foamy container as a place to keep a lot of the sugar. (B) [substeps] The higher the lid of the container, the more likely the mealworms are to poke holes in the lid and become trapped. They can fly in a pinch and escape. (C) [substeps] The sides of the container should be airtight and keep them from breaking. That would mean sealed containers with glass or flint flakes, which could potentially expose them to bacteria or germs. (D) [substeps] Avoid containers made of things like cardboard, or any containers lined in fabric. These surfaces will be easy for the worms to latch onto and climb up, which could allow them to get out.
