How do I know whether my mealworms are dead?

You can determine if your mealworms are dead by looking for signs of movement; healthy mealworms will wriggle when disturbed. If they are stiff, discolored, or have an unusual odor, these are also indicators of death. Additionally, dead mealworms may show signs of desiccation or become shriveled. If you're unsure, it's best to err on the side of caution and remove any suspicious mealworms from the habitat.
