Bearded dragons are fascinating reptiles known for their unique appearance and docile nature. As omnivorous creatures, their diet primarily consists of vegetables, fruits, and insects. While it’s clear that insects are an essential part of their nutrition, many reptile enthusiasts wonder whether bearded dragons can eat flies. In this comprehensive guide, we will delve into the topic, exploring the benefits and risks associated with feeding flies to bearded dragons. We will also provide practical solutions to ensure the health and well-being of your pet.

The Nutritional Needs of Bearded Dragons

To understand whether flies are suitable for bearded dragons, it’s important to grasp their nutritional requirements. Bearded dragons require a balanced diet consisting of protein, vitamins, minerals, and fiber. The protein component is crucial for their growth, development, and overall health. While they primarily consume insects, it’s necessary to offer a variety of insects to ensure a diverse nutrient profile.

In terms of protein, bearded dragons require around 20-30% of their diet to come from insects. This protein helps support muscle development, tissue repair, and immune system function. Additionally, they need adequate amounts of calcium and phosphorus for bone health, as well as vitamins A and D3 for proper growth and metabolism. Fiber-rich vegetables and fruits are also necessary to maintain digestive health and prevent constipation.

The Benefits of Feeding Flies to Bearded Dragons

Flies, especially small fruit flies or flightless fruit flies, can be a valuable addition to a bearded dragon’s diet. They offer several benefits:

  1. Protein Content: Flies are protein-rich insects, which is vital for the growth and maintenance of a bearded dragon’s body. Protein aids in muscle development, tissue repair, and immune system function. It provides the necessary building blocks for a healthy reptile.
  • Exercise and Hunting Stimulation: Feeding flies can provide an opportunity for your bearded dragon to exhibit natural hunting behaviors. This activity not only stimulates their mental and physical well-being but also prevents boredom. The act of chasing and capturing flies can mimic their natural foraging instincts.
  • Variety in Diet: Offering flies as part of a varied diet ensures that your bearded dragon receives a wide range of nutrients. By incorporating different insects, vegetables, and fruits, you mimic their natural diet and promote overall health. A diverse diet helps prevent nutrient deficiencies and promotes optimal well-being.
  • Environmental Enrichment: Allowing your bearded dragon to engage in natural behaviors, such as hunting flies, provides environmental enrichment. This stimulation is essential for their mental and emotional health. It can reduce stress and promote a more active lifestyle.

Risks Associated with Feeding Flies to Bearded Dragons

While flies can offer nutritional benefits, there are some risks to consider:

  1. Pesticide Exposure: Wild flies may come into contact with pesticides or other harmful chemicals, which can pose a risk to your bearded dragon’s health. It is crucial to source flies from reputable suppliers or ensure they are from organic sources. By doing so, you can minimize the risk of pesticide exposure and its potential negative effects on your reptile.
  • Disease Transmission: Flies can carry various diseases and parasites that could be harmful to your bearded dragon. This risk is particularly high if the flies are wild-caught. Ensuring the flies come from a reliable source and practicing good hygiene is essential. Regularly inspect the flies for any signs of illness or infestation before feeding them to your pet.
  • Fly Size: The size of the flies you feed your bearded dragon is important. Large flies could pose a choking hazard or cause digestive issues. It is advisable to offer small fruit flies or flightless fruit flies that are appropriate for their size. This ensures that the flies are easily consumed and digested, reducing the risk of any complications.
  • Allergic Reactions: Just like humans, bearded dragons can develop allergies to certain foods. Although rare, some bearded dragons may exhibit allergic reactions to flies. Monitor your pet closely after introducing flies into their diet and seek veterinary attention if you notice any unusual symptoms or behaviors.

Precautions and Guidelines for Feeding Flies to Bearded Dragons

To safely incorporate flies into your bearded dragon’s diet, follow these precautions and guidelines:

  • Source Flies from Reputable Suppliers: Purchase flies from reliable suppliers that provide healthy, pesticide-free insects. This reduces the risk of pesticide exposure and disease transmission. Research and choose suppliers known for their quality and commitment to providing safe and nutritious insects for reptiles.
  • Gut-Loading: Gut-loading is the process of feeding insects nutritious foods before offering them to your bearded dragon. This ensures that the flies are packed with essential nutrients. Provide gut-loading foods such as fresh fruits, vegetables, and high-quality commercial insect gut-load diets. The insects will absorb these nutrients, making them more nutritious for your bearded dragon.
  • Dusting with Calcium and Multivitamins: Before feeding the flies to your bearded dragon, dust them with calcium powder or a calcium and multivitamin supplement. This enhances the nutrient profile of the insects and helps maintain proper calcium levels in your reptile’s body. Calcium is crucial for bone health, muscle function, and overall well-being.
  • Moderation is Key: Flies should be offered as a supplemental food item rather than a primary source of nutrition. While they provide valuable protein, they should not replace the necessary variety of vegetables and other insects in your bearded dragon’s diet. Flies should make up only a small portion of their overall diet.
  • Observation and Monitoring: Keep a close eye on your bearded dragon’s health and behavior when introducing flies into their diet. Observe for any adverse reactions or changes in appetite, digestion, or behavior. If you notice any issues, consult a reptile veterinarian for guidance and support.

Alternatives to Feeding Flies

If you’re concerned about the risks associated with feeding flies to your bearded dragon, there are alternative insect options that offer similar nutritional benefits. Consider incorporating the following insects into their diet:

  • Crickets: Crickets are readily available and provide a good source of protein. Ensure the crickets are appropriately sized and gut-loaded before feeding them to your bearded dragon. They are a popular staple insect for many reptile owners and offer a good nutritional profile.
  • Dubia Roaches: These roaches are a popular choice for reptile owners due to their high protein content and low-fat content. They are also easy to breed and maintain. Dubia roaches provide a nutritious alternative to flies and can be a suitable addition to your bearded dragon’s diet.
  • Mealworms: Mealworms are another common staple insect for bearded dragons. However, they should be offered in moderation due to their high-fat content. Consider using them as an occasional treat rather than a regular part of the diet. They can be a valuable source of protein but should not replace the necessary variety of vegetables and other insects.


In summary, flies can be a suitable addition to a bearded dragon’s diet, offering valuable protein and stimulation. However, it’s essential to consider the risks associated with wild-caught flies and ensure they are sourced from reputable suppliers. Following precautions, such as gut-loading and dusting with calcium, will help maintain a balanced diet for your bearded dragon. If you prefer to avoid flies altogether, there are alternative insects available that provide similar nutritional benefits. By providing a varied and well-balanced diet, you can ensure the optimal health and longevity of your beloved bearded dragon.
