Crested Gecko Burns: Heat Injury Signs, Severity & Immediate Steps

Crested geckos are especially vulnerable to heat injury because they are ectothermic and depend on their environment for warmth. In captivity, burns most often happen when a gecko can get too close to an exposed heat source or cannot move away from an overheated area. Reptiles also may not pull away from dangerous heat as quickly as mammals do, so tissue damage can continue longer than a pet parent expects.

Common causes include exposed heat bulbs, ceramic heat emitters placed too close to the enclosure top, climbing onto hot screen lids, unregulated heat mats, and direct contact with hot surfaces. Reptile references also warn against "hot rocks" and other contact heaters because they are a frequent source of thermal burns. Even if a device is marketed for reptiles, it can still cause injury if the wattage is too high, the thermostat fails, or the probe is placed incorrectly.

For crested geckos, husbandry matters a lot because this species does best with relatively gentle temperatures and can overheat easily. A setup that is safe for a desert reptile may be dangerous for a crested gecko. Burns can happen during heat waves, after a bulb change, when a thermostat malfunctions, or when a gecko starts climbing in a new part of the enclosure and reaches a hot screen or fixture.

See your vet immediately if the skin is blistered, open, wet, peeling, charred, white, gray, or black, or if your crested gecko seems weak, painful, dehydrated, or unable to climb normally. Burns on the face, feet, tail base, belly, or over a large body area are also urgent. Reptile burns can become infected and may deepen over the next few days, so a wound that looks small at first can still be serious.

Same-day care is also important if your gecko stops eating, keeps the eyes closed, shows abnormal posture, has a foul smell from the wound, or the enclosure may have overheated enough to cause both a burn and heat stress. If you know your gecko touched a bulb, heater, or hot screen, it is safest to call an exotics-capable clinic even before the skin changes fully appear.

Home monitoring may be reasonable only for a very small, superficial area with mild discoloration and no blistering, no open skin, normal activity, and normal appetite. Even then, close observation is essential because reptile thermal injuries can declare themselves later. If the area worsens at all over 24-72 hours, your gecko should be rechecked promptly.

Your vet will start with a full physical exam and a careful husbandry history. Expect questions about enclosure temperatures, thermostat type, probe placement, bulb wattage, humidity, recent heat source changes, and whether your gecko had direct access to the heater or screen top. In reptiles, the history and exam are often the main tools for diagnosing a thermal burn and judging how deep it may be.

Treatment depends on burn depth, location, and whether infection or dehydration is present. Your vet may clean the wound, remove loose dead tissue if needed, apply reptile-appropriate topical therapy, and prescribe pain control and sometimes antimicrobials when infection risk is high or tissue is already compromised. Some burns need bandaging, though bandage options can be limited in small geckos and must be changed carefully to keep the wound clean.

For more severe injuries, your vet may recommend fluids, assisted feeding support, sedation for wound care, culture or cytology if infection is suspected, and hospitalization for monitoring. They will also help you correct the enclosure setup so the burn can heal and the injury does not happen again. Recovery can take weeks to months, especially for deeper burns.

If your crested gecko may have been burned, first remove access to the heat source. Set up a clean, simple recovery enclosure with paper towels, easy access to water, and safe species-appropriate temperatures. Do not place the gecko back into the original setup until the heating problem has been corrected and checked with reliable thermometers and a thermostat.

Do not use ice, butter, petroleum products, over-the-counter antibiotic ointments, silver creams, lidocaine products, or human burn gels unless your vet specifically tells you to. Many human products are not appropriate for reptiles, and greasy products can trap debris or interfere with wound assessment. Avoid peeling skin, scrubbing the area, or trying to cut away dead tissue at home.

Keep the enclosure very clean because infection is one of the biggest risks after a reptile burn. Change paper towels often, reduce climbing hazards, and handle your gecko only when necessary. Watch closely for worsening discoloration, swelling, discharge, odor, reduced appetite, or trouble moving. If any of those appear, or if your gecko seems painful or weak, contact your vet right away.
