Mealworms are the larvae of darkling beetles, and are commonly used in salads and as ingredients for protein bars. Most importantly, they are recommended as feeder insects for small captive reptiles that require high levels of protein to stay healthy, just like your bearded dragon! However, there’s a ruckus on whether mealworms are truthfully good, or rather, safe for beardies to eat, and we’ll be discussing all of that in a jiffy!

Bearded dragons can eat mealworms and they’re good for them in moderate amounts. They provide a healthy amount of protein, minerals, and vitamins that are needed collectively to improve and complement your beardie’s vitality. Mealworms also make a good part of the staple diet for bearded dragons in captivity.

Figuring out whether a coined “staple dietary item” is safe for your pet is an honorary thing to do. It’s important to be fully aware of what your bearded dragon can eat and how to feed it for its safety.

Are Mealworms Dangerous For Bearded Dragons? The Surprising Answer

Mealworms are nutritious for bearded dragons and there’s no argument around that fact. However, not all nutrient-dense bugs are great for them. Some are simply difficult to digest or may contain way too many goodies – fat or protein – than your beardie truly needs.

The problem with mealworms is that they’re tedious to digest, more so by younger beardies than adults because hatchlings require a faster digestive process to stay healthy. Since mealworms have a tough exoskeleton that takes time to digest and get excreted, it could lead to impaction and other complications for your bearded dragon.

In a handful of cases, some bearded dragons have died from impaction by eating too many mealworms, particularly the baby and juvenile beardies. The only way to go around this is by feeding your pet mealworms moderately and in appropriate sizes.

While it may be extreme to completely rule out feeding mealworms to beardies, there is still the possibility of injuries from impaction and even death. Nevertheless, as long as the mealworms are fed sparingly, the chances of your dragon meeting problems along the way are relatively low. It’s safe to say that mealworms are 30% dangerous for bearded dragons, and 70% safe.

5 Tips For Safely Feeding Mealworms To Your Bearded Dragon

The best way to feed mealworms to bearded dragons is once or twice a week as a varied diet. This means that you must never feed mealworms alone as the meal of the day. Your beardie should have a few crickets or roaches and its required vegetables in addition to the mealworms to aid digestion and provide your pet with a complete value of nutrients.

Before we get into it, you must know the percentage and balance of protein and vegetables your beardie requires depending on its age. The table below will help you figure that out.

Age (months)Percentage
0 – 2 (Baby stage)30% greens, 70% grubs
3 – 6 (Juvenile stage)30% greens, 70% grubs
6 – 9 (Subadult stage)40% greens, 60% grubs
9 – 18+ (Adult stage)70% greens, 30% grubs

How To Safely Feed Mealworms To Your Bearded Dragon

  1. Put the mealworms in a small cup so that your pet can pick the worms up easily. Mealworms are fond of smuggling away and are too flat for bearded dragons to pick them up from the floor as they move.
  2. Ensure that you feed your pet at most 8 mealworms at a time. Some pet owners may prefer to feed their beardies an unlimited amount of mealworms in a specific period, but this is highly dangerous as the possibility of impaction, in this case, is high and often observed.
  3. The mealworms should be a complement to the meal of the day. Your beardie should also eat healthy vegetables and other protein sources dusted with calcium supplements so that the possibility of impaction is low.
  4. Take note of the size. Do not feed your pet mealworms that are way bigger than the space between its eyes. The size of the insect matters tremendously; if your beardie fills itself with oversized feeder grubs, it could stretch out its belly and cause temporary paralysis of the hind legs. It’s also very uncomfortable and painful for the beardie suffering from it.
  5. Never feed mealworms to your bearded dragon daily. Too much rigorous digestion can cause your pet to develop stomach problems, loss of appetite, and lethargy. You must only feed mealworms not more than twice a week.
