Can Bearded Dragons Eat Nightcrawlers


Bearded dragons are popular pets due to their docile nature and fascinating appearance. As responsible owners, it is essential to provide them with a well-rounded and nutritious diet. While commercial reptile food is readily available, many owners wonder if they can incorporate natural prey items into their bearded dragon's diet, such as nightcrawlers. In this article, we will explore the nutritional value of nightcrawlers, their potential benefits and risks for bearded dragons, and provide guidance on incorporating them into their diet.

Nutritional Value of Nightcrawlers

High Protein Content

Nightcrawlers, also known as earthworms, are rich in protein, making them an attractive food source for bearded dragons. Protein is essential for growth, tissue repair, and the production of enzymes and hormones. A diet lacking in sufficient protein can lead to stunted growth and overall health issues in bearded dragons.

Essential Amino Acids

Amino acids are the building blocks of protein, and some are classified as essential, meaning the body cannot produce them on its own and must acquire them through diet. Nightcrawlers offer a complete profile of essential amino acids, including lysine, methionine, and tryptophan. Including foods that provide these amino acids can contribute to a balanced and healthy diet for your bearded dragon.

Vitamins and Minerals

Nightcrawlers are a good source of vitamins and minerals necessary for the overall well-being of bearded dragons. They contain vitamins A, D, E, and K, which are essential for proper bone development, immune function, and overall growth. Additionally, nightcrawlers are rich in calcium, phosphorus, and magnesium, crucial minerals for maintaining healthy bones, muscle function, and enzyme activity in bearded dragons.

Benefits of Nightcrawlers for Bearded Dragons

Variety in Diet

Offering a diverse diet is crucial to ensure your bearded dragon receives a wide range of nutrients. Nightcrawlers can be a valuable addition to their diet, providing a different texture and taste compared to commercial reptile food. Introducing new food items can also prevent monotony and increase the overall appetite of your bearded dragon.

Natural Hunting Behavior

Bearded dragons are natural hunters, and allowing them to exercise this behavior can contribute to their overall mental and physical well-being. Feeding nightcrawlers can stimulate their hunting instincts, providing a more enriching feeding experience for your pet. However, it is important to ensure the nightcrawlers are appropriately sized and easy for your bearded dragon to consume.


In addition to their nutritional benefits, nightcrawlers have a high moisture content, making them a hydrating food option for bearded dragons. Adequate hydration is crucial for their overall health and proper organ function. Including moisture-rich foods like nightcrawlers can help maintain optimal hydration levels in your bearded dragon.

Cost-effective Option

Commercial reptile food can be expensive, especially for owners with multiple bearded dragons or those on a tight budget. Nightcrawlers are a cost-effective alternative that can provide a nutritious and balanced diet for your pet. They are readily available in most pet stores and can be purchased in bulk for additional savings.

Risks and Considerations

Parasite Concerns

One of the main risks associated with feeding nightcrawlers to bearded dragons is the potential presence of parasites. Earthworms harvested from outdoor environments may carry various parasites that can be harmful to reptiles. To minimize this risk, it is crucial to source nightcrawlers from reputable suppliers or breed them yourself in a controlled environment. Additionally, freezing the nightcrawlers before offering them to your bearded dragon can help eliminate any potential parasites.

Allergic Reactions

Some bearded dragons may be sensitive or allergic to certain food items, including nightcrawlers. It is important to monitor your pet closely after introducing them to nightcrawlers for the first time. Look for any signs of distress, such as vomiting, diarrhea, or changes in behavior. If any adverse reactions occur, it is best to discontinue feeding nightcrawlers and consult with a veterinarian.

Size Considerations

Nightcrawlers come in various sizes, and it is crucial to choose ones that are appropriate for your bearded dragon's size. Feeding overly large nightcrawlers can pose a choking hazard or cause digestive issues. As a general rule, the size of the nightcrawler should be no larger than the space between your bearded dragon's eyes.

Moderation is Key

While nightcrawlers offer numerous benefits, they should be fed in moderation to avoid nutritional imbalances. It is important to remember that a well-rounded diet for bearded dragons should consist of a variety of food items, including insects, vegetables, and fruits. Nightcrawlers should be viewed as a supplement to their diet rather than the sole food source.


Incorporating nightcrawlers into a bearded dragon's diet can provide numerous nutritional benefits and enrichment opportunities. Their high protein content, essential amino acids, vitamins, and minerals make them a valuable addition to a well-rounded diet. However, it is important to consider the potential risks associated with parasites, allergies, and appropriate sizing. By following proper sourcing techniques, monitoring your pet's reactions, and practicing moderation, you can safely introduce nightcrawlers as a part of your bearded dragon's diet. Remember to consult with a veterinarian for personalized advice and to ensure the overall health and well-being of your beloved reptile companion.
