Do Crested Geckos Bite? Understanding Their Behavior and Habits

Crested geckos have become one of the most popular pets across the world. However, a pressing question lingers on the lips of both potential and current owners: do these geckos bite? Misconceptions swirl, fostering unease among enthusiasts and novice keepers alike.

Do Crested Geckos Bite?

Yes, crested geckos do bite but it’s not a common behavior and is rarely a cause for concern. When compared to common household pets like cats or dogs, crested geckos are considerably less prone to biting.

A dog might bite when threatened, or a cat might swipe when annoyed, but a crested gecko typically reserves its bite for specific circumstances. More often than not, their bites are neither aggressive nor particularly painful.

It’s rare for these geckos to exhibit biting behavior. If they do decide to bite, it’s usually a product of feeling threatened, stressed, or, on rare occasions, confusing a finger for food during feeding times. However, with proper handling techniques, the likelihood of a bite is significantly diminished.

Does a Crested Gecko Bite Hurt?


Firstly, the teeth of a crested gecko are fine and numerous, adapted primarily for a diet of soft fruits and insects. Unlike some other reptiles that have larger, more forceful jaws, crested geckos have relatively small, needle-like teeth.

Dr. Sarah Thompson, a renowned reptile veterinarian, says, “The bite of a crested gecko can best be described as a quick pinch. Their dental anatomy isn’t designed to deliver a powerful grip but to aid in their feeding habits.”

From a personal standpoint, as an avid crested gecko keeper, I’ve experienced a bite or two during handling or feeding sessions. The feeling can best be described as a slight pinch, startling but hardly painful. It’s similar to the sensation of being pricked by a thorn but without any lasting discomfort.

Why Do Crested Geckos Bite?

Below are the main reasons why do crested geckos bite?

1. Fear or Defense Mechanisms

Like many creatures, when threatened, a crested gecko’s first instinct is survival. If they perceive a hand or an object as a potential threat, they might resort to biting as a defense mechanism.

Remember, in their natural habitat, they face various predators. Thus, biting is an ingrained protective behavior.

Recommendation: Always approach your gecko in a calm and gentle manner. Avoid sudden movements, and with time, they will associate your hand with safety rather than threat.

2. Mistaking Fingers for Food

Sometimes, the bite isn’t personal; it’s a case of mistaken identity. Crested geckos primarily hunt insects like locusts, and a wriggling finger might, to an overly enthusiastic gecko, appear as a juicy treat. As comical as it might sound, it’s a common occurrence, especially for younger, more impulsive geckos.

Guideline: When feeding your gecko, use feeding tongs or ensure that your fingers are not in the direct line of sight when introducing food.

Mating Behavior

Though it’s less common, male geckos might occasionally bite when they are in breeding mode. During this time, they can be more aggressive than usual. As a responsible owner, understanding their mating cycles and behavior can help in averting such situations.

Territorial Disputes

Beyond the mating season, crested geckos are innately territorial. Their vivarium is their kingdom, and any perceived intrusion might be met with assertive resistance, which could include biting. Actionable Advice: Ensure each gecko has ample space, hiding spots, and territorial landmarks within their habitat.

Treatments and Precautions for Crested Gecko Bites

The aftermath of a crested gecko bite is usually mild, but it’s essential to understand what to do next.

Immediate First-Aid Steps:

  1. Clean the Area: Gently wash the bitten area with warm water and mild soap. It helps prevent any potential infections.
  2. Apply Antiseptic: Once clean, dab an antiseptic solution to disinfect.
  3. Bandage if Necessary: If the bite broke the skin, which is rare, apply a small bandage.

Proactive Measures to Avoid Bites:

  1. Handle with Care: Always approach your gecko calmly, especially if you’re introducing a new hand into their habitat.
  2. Recognize Stress Signs: Geckos tend to arch their backs, puff up, or open their mouths as a sign of distress. If you notice these, give them some space.
  3. Avoid Sudden Movements: Rapid motions can startle your gecko. When you’re near their territory, be smooth and predictable in your movements.
  4. Establish Trust: Spend time near their habitat without necessarily picking them up. It helps them get used to your presence.
  5. Limit Handling After Feeding: Like many reptiles, crested geckos can become agitated if handled soon after feeding.
