How do I keep my boa constrictor warm in winter?
Maintain a warm side of 88–92°F (31–33°C) to ensure your boa stays comfortable during the colder months.
Summer Heat Limits
During the summer, it's crucial to keep your boa's warm side at 88–92°F (31–33°C) to prevent overheating. Avoid direct sunlight and use a heat mat or under-tank heater to maintain the temperature.
Ensure the cool side is 78–82°F (26–28°C) to allow your boa to thermoregulate. Monitor the temperature with a reliable digital thermometer placed at the warm and cool sides of the enclosure.
- Keep the warm side at 88–92°F (31–33°C)
- Maintain the cool side at 78–82°F (26–33°C)
- Use a heat mat or under-tank heater
- Monitor with a digital thermometer
Winter Temperature and Daylight Changes
In winter, the temperature on the warm side should remain at 88–92°F (31–33°C), while the cool side can be slightly lower, around 78–82°F (26–28°C).
Daylight hours should be reduced to mimic the shorter days of winter, which can help regulate your boa's activity levels. Aim for 10–12 hours of light per day.
- Warm side: 88–92°F (31–33°C)
- Cool side: 78–82°F (26–28°C)
- Reduce daylight hours to 10–12 per day
Dry Air and Activity Changes
Winter can bring dry air, which can be uncomfortable for your boa. Use a humidifier to maintain humidity levels between 55–70%.
Your boa may become less active during the winter. This is normal and should not be a cause for concern. Continue with regular feeding and handling to keep them engaged.

Seasonal Hazards
Be cautious of seasonal hazards such as holiday plants, which can be toxic to reptiles. Keep poinsettias, holly, and mistletoe out of reach.
Guests and fireworks can be stressful for your boa. Provide a quiet, secure area in the enclosure and consider using a pheromone spray to help calm them.
If you plan to travel, make sure someone is available to care for your boa and maintain the enclosure's temperature and humidity.

Seasonal Checklist
Before the winter arrives, ensure your boa's enclosure is ready. Check the heating and cooling systems, and make sure the thermometer is functioning properly.
Monitor your boa's behavior closely during the winter. Look for signs of stress or illness, such as changes in appetite or activity levels.
Keep a record of the enclosure's temperature and humidity levels to ensure they remain within the recommended range.
- Check heating and cooling systems before winter
- Monitor behavior for signs of stress or illness
- Keep a record of temperature and humidity levels
