Respiratory infections are among the most serious health issues leopard geckos can develop. They usually result from poor environmental conditions, especially low temperatures combined with excess humidity. Because geckos are ectothermic, their immune system depends heavily on correct husbandry, and when conditions are off, their body can no longer fight off bacteria.
Left untreated, respiratory infections can be fatal. Recognizing early symptoms and maintaining correct husbandry are the keys to prevention.
Since this condition is one of the major illnesses leopard geckos face, it is also included in the Health Issues & Common Diseases hub, where it stands alongside other preventable conditions like shedding problems and MBD.
Causes of Respiratory Infections
Respiratory infections in leopard geckos almost always stem from husbandry errors that compromise the immune system.
1. Incorrect Temperatures
- If the enclosure is too cold, geckos cannot digest food properly.
- A weak metabolism reduces the body’s ability to fight off bacteria.
2. Excess Humidity
- Constantly high humidity (above 50%) creates an ideal breeding ground for bacteria.
- Poor ventilation traps moisture, leading to damp, stagnant air.
3. Stress & Weak Immunity
- Stress from handling, cohabitation, or poor diet lowers immune resistance.
- Malnourished geckos are far more prone to infections.
Maintaining stable humidity and proper heat gradients is the most effective way to prevent respiratory infections. Best practices are detailed in the Humidity & Temperature Management cluster, where you’ll find optimal ranges and setup strategies.
Symptoms of Respiratory Infections
Respiratory infections can develop gradually, but the signs are often very noticeable once the illness progresses. Recognizing them early makes treatment far more effective.
Early Symptoms
- Wheezing or faint clicking sounds during breathing.
- Excessive time spent under the heat source, as the gecko seeks warmth.
- Reduced appetite and activity.
Visible Symptoms
- Bubbles or mucus around the nostrils and mouth.
- Open-mouth breathing.
- Swelling around the throat area.
Advanced Symptoms
- Severe lethargy.
- Weight loss due to prolonged refusal to eat.
- Constant gaping or struggling to breathe.
Since these infections are a leading cause of leopard gecko illness, they are also highlighted in the Health Issues & Common Diseases hub alongside MBD, parasites, and shedding complications.
Treatment Options
Respiratory infections require swift action, as untreated cases can quickly become life-threatening.
At-Home Support (Early Stages Only)
- Raise enclosure temperatures slightly within the safe range to boost immune response.
- Improve ventilation to reduce stagnant air.
- Ensure humidity remains between 30–40%, with a humid hide available for shedding.
Veterinary Care (Essential for Moderate to Severe Cases)
- Antibiotics: Prescribed by an exotic veterinarian after proper diagnosis.
- Fluid therapy: Supports hydration in weakened geckos.
- Nebulization treatments: Sometimes used to deliver medication directly to the respiratory system.
Because many of these treatments require medical expertise, most cases must be handled under the guidance of an exotic vet. Detailed advice on preparing for reptile veterinary visits is covered in the Vet & Medical Care .
Prevention of Respiratory Infections
Respiratory infections are among the most preventable illnesses in leopard geckos when correct husbandry is maintained.
Key Prevention Strategies
- Temperature Control: Keep a proper heat gradient — warm side 88–92°F, cool side 75–80°F.
- Humidity Balance: Maintain overall humidity at 30–40%, with localized humidity in the shed hide only.
- Good Ventilation: Ensure airflow in the enclosure to prevent damp, stagnant air.
- Cleanliness: Regular cleaning prevents bacterial growth that can trigger infections.
- Stress Reduction: Avoid overcrowding and overhandling, which weaken the immune system.
For a step-by-step breakdown of how to set up and regulate these conditions, see the Humidity & Temperature Management cluster, which provides detailed instructions on maintaining safe, stable environments.
Conclusion
Respiratory infections are one of the most dangerous yet preventable conditions affecting leopard geckos. By maintaining proper temperatures, balanced humidity, and good ventilation, most cases can be avoided entirely.
When symptoms such as wheezing, mucus around the nose, or open-mouth breathing appear, quick action is essential. Early husbandry corrections may help mild cases, but advanced infections require professional care.
This condition fits within the broader overview of illnesses discussed in the Health Issues & Common Diseases hub, reminding keepers that prevention begins with correct husbandry.

Common symptoms include wheezing, bubbles around the nose or mouth, open-mouth breathing, lethargy, and refusal to eat.
Can respiratory infections in leopard geckos be treated at home?
Mild cases may improve with corrected temperatures and ventilation, but most require veterinary care with antibiotics.
How do I prevent my leopard gecko from getting a respiratory infection?
Prevention includes maintaining proper heat gradients, keeping humidity at 30–40%, ensuring ventilation, and reducing stress.
