Ball Python Respiratory Infection
Respiratory infections (RIs) are one of the more serious health issues ball pythons can develop. Unlike stuck shed or feeding refusal, a respiratory infection almost always requires veterinary treatment. Catching it early makes a significant difference in outcome.

Signs of a Respiratory Infection
Common respiratory infection symptoms in ball pythons include:
- Wheezing or crackling sounds when breathing
- Mucus or discharge from the mouth or nostrils
- Bubbling saliva around the mouth or nostrils
- Open-mouth breathing (gaping) when not feeding or threatened
- Lethargy beyond normal resting behavior
- Holding the head elevated for prolonged periods while breathing or showing obvious breathing difficulty
- Loss of appetite alongside other symptoms
A single symptom in isolation — like occasional open-mouth breathing after a large meal — isn't always cause for alarm. A combination of symptoms, or any symptom that persists, warrants a vet visit.
Causes
Respiratory infections in ball pythons are most commonly caused by:
- Temperatures that are too low — the most common cause; a cold snake has a suppressed immune system
- Poor ventilation combined with persistently damp conditions — stagnant, wet air allows bacterial and viral pathogens to build up
- Stress — chronic stress suppresses immune function
- Introduction of a new animal without proper quarantine
RIs can be bacterial, viral, or parasitic in origin. Bacterial infections are the most common and are generally treatable with antibiotics. Viral respiratory diseases are generally more difficult to treat than bacterial infections and require veterinary diagnosis.
What to Do
1. Check Your Husbandry Immediately
Before anything else, verify your temperatures and humidity. A snake kept too cold is far more susceptible to respiratory infections. Ensure your warm hide surface is reaching 88–92°F and your ambient cool side is 76–80°F. Correct any issues immediately.
2. See a Reptile Vet
Respiratory infections do not resolve on their own. If your ball python is showing symptoms, book a vet appointment as soon as possible. The vet may recommend imaging, cultures, or other diagnostics depending on the severity of the infection. Do not attempt to treat a respiratory infection at home with over-the-counter products.
3. Isolate If You Have Multiple Snakes
If you keep multiple snakes, isolate the affected animal immediately. Some respiratory pathogens are contagious. Wash your hands thoroughly between handling animals and use separate equipment.
Prevention
- Maintain correct temperatures year-round — use a thermostat, not guesswork
- Ensure the enclosure dries out between mistings — don't keep substrate constantly saturated
- Provide adequate ventilation, especially in PVC or glass enclosures
- Quarantine all new animals for a minimum of 90 days before introducing them to a collection
- Minimize chronic stress — correct hides, minimal disturbance, appropriate handling frequency

When to Seek Emergency Care
Seek urgent veterinary care if your ball python is:
- Gasping for air
- Open-mouth breathing that doesn't stop
- Producing thick mucus blocking the nostrils or mouth
- Severely lethargic or unresponsive
