Can Bearded Dragons Eat Mealworms? Yes, Gut-Loaded
Yes, bearded dragons can eat mealworms. VCA Animal Hospitals lists calcium-dusted mealworms with crickets and dubia roaches as suitable feeder insects for bearded dragons. Like every feeder, mealworms should be gut-loaded within 12 hours before feeding and dusted with calcium. They work best as one insect in a rotation rather than the only one. Buy them from a pet store or breeder; never collect insects from outdoors.

Where mealworms fit among feeder insects
VCA describes the bearded dragon diet as roughly half plants and half insects, varying with age. Young dragons are mainly insectivores; adults eat more plants. For the insect half, VCA lists calcium-dusted crickets, mealworms and dubia cockroaches, along with silkworms and hornworms.
VCA treats waxworms and superworms differently, recommending them only sparingly and not daily because they are high in fat and can cause obesity. Mealworms are on the main list, which makes them a reasonable regular feeder in rotation with others.
Gut-loading and dusting make the insect useful
An insect is only as nutritious as what it ate. VCA recommends gut-loading feeders within 12 hours of offering them to the dragon, and notes that vegetables can be fed to the insects beforehand. That way the insect carries extra nutrition into your dragon.
Dusting matters just as much. The Merck Veterinary Manual names metabolic bone disease, caused by diets low in calcium relative to phosphorus, low vitamin D3 or poor UVB lighting, as the most common bone disease in reptile practice. VCA advises a phosphorus-free calcium powder daily and a calcium powder with vitamin D3 two to three times a week.
Offering food in the warm end of a properly heated reptile terrarium helps digestion; our bearded dragon enclosure guide explains how to set up that gradient.
How to feed mealworms
Keep mealworms in a ventilated container with a dry bedding such as oats or bran and a slice of vegetable for moisture and gut-loading. Before a meal, put the number you plan to feed into a small bag or cup with calcium powder and shake gently to coat them.
Serve them in a smooth-sided shallow dish so they cannot burrow into the substrate and escape. Choose mealworms sized for your dragon; small juveniles do better with smaller insects such as crickets until they grow. Remove any uneaten worms after the meal.
Feed insects from a smooth-sided dish or with tongs so they cannot escape into the substrate of the bearded dragon tank; the rest of the habitat basics are in our reptile supplies.
How many and how often
Juveniles eat insects once or twice a day, VCA says, and need more insects than adults. Rotating mealworms with crickets and dubia roaches through the week gives a growing dragon variety and keeps it interested.
Adults are fed every 24 to 72 hours depending on appetite, and their diet shifts toward plants. For an adult, a small serving of mealworms a few times a week as part of the insect portion is reasonable. Watch body shape and adjust if your dragon is gaining weight.
Why not wild-caught insects
VCA warns against collecting wild or garden insects because fertilizers and insecticides may make them toxic. Store-bought or home-bred mealworms avoid that risk entirely.
VCA also says never to feed fireflies, which are generally toxic to lizards. If you breed your own feeders, keep the colony away from outdoor insects and chemicals, and feed the colony clean vegetables and grain. A dragon that eats a firefly needs a call to a reptile vet right away.
Signs to watch and when to see a vet
Merck notes that reptiles become obese quickly on excess calories with little exercise, so a dragon that is rounding out may need fewer fatty insects and more greens. Merck lists poor appetite, lethargy, abnormal walking, a swollen or distorted jaw or limbs, muscle twitching and tetany as signs of metabolic bone disease.
Those signs need a reptile veterinarian soon. So does a dragon that stops eating, strains without passing droppings, or loses weight. Bring details of the insects, dusting products and lighting you use.

Common questions
Can bearded dragons eat mealworms every day?
They can be part of the daily insect portion for a juvenile, but rotating them with crickets and dubia roaches is better. Adults eat fewer insects overall, so mealworms a few times a week is plenty.
Can baby bearded dragons eat mealworms?
Small mealworms can be offered occasionally, but many keepers rely mainly on appropriately sized crickets and roaches for babies. Whatever the insect, it should be gut-loaded and dusted with calcium, as VCA recommends.
Can bearded dragons eat dried mealworms?
Live insects are what VCA's guidance describes, because they can be gut-loaded and are easy to dust. Dried mealworms cannot be gut-loaded and are a poorer substitute, so use them only occasionally if at all.
Are mealworms or superworms better for bearded dragons?
VCA lists mealworms among suitable regular feeders and says superworms should be fed sparingly, not daily, because they are high in fat and can cause obesity. Mealworms are the more routine choice.
How many mealworms should I feed my bearded dragon?
It depends on age and size. Juveniles need more insects than adults, and adults eat mostly plants. Offer what your dragon eats in one sitting as part of a mixed insect portion, and ask a reptile vet if unsure.
