Species care guide
Milk Snake
Milk snakes (Lampropeltis triangulum) are popular, docile colubrids known for their vibrant red, black, and white/yellow banded patterns that mimic venomous coral snakes. These hardy, medium-sized constrictors make excellent pets for beginners due to their manageable size, calm temperament, and relatively simple care requirements. They are native to North and Central America and adapt well to captivity.
Difficulty
Beginner
Lifespan
15-20 years with proper care
Adult size
24-36 inches (some subspecies may reach 48 inches)
Humidity
50-60%
Temperature
Maintain a thermal gradient with basking spot on one end and cooler area on opposite end. Use under-tank heater or ceramic heat emitter with thermostat control.
Hot side
85-88°F
Cool side
75-80°F
Night
70-75°F
Humidity
Moderate humidity levels with good ventilation to prevent respiratory issues. Provide water bowl and occasional light misting during shedding periods.
Target range: 50-60%
Feeding
Feed appropriately sized frozen-thawed prey items. Prey should be roughly the same width as the thickest part of the snake's body. Feed in separate container to reduce substrate ingestion.
Frequency: Every 7-10 days for adults, every 5-7 days for juveniles
micesmall rats (for larger specimens)
Handling
Generally docile and tolerate handling well. Support body when lifting, move slowly and confidently. Handle 2-3 times per week maximum. Avoid handling during shedding, after feeding (wait 48-72 hours), or if snake appears stressed.
Health
Hardy species with few health issues when proper husbandry is maintained. Monitor for signs of illness including mites, respiratory infections, or stuck shed. Consult qualified reptile veterinarian for any health concerns.
- respiratory infections from poor humidity/temperature
- mites
- stuck shed
- feeding refusal during winter months
- scale rot from overly wet conditions
Breeding
Sexually mature at 2-3 years. Require winter cooling period (brumation) at 50-55°F for 8-12 weeks to stimulate breeding. Females lay 6-24 eggs after 60-day gestation. Eggs incubate at 78-80°F for 55-65 days. Breeding should only be attempted by experienced keepers.
Morphs
Popular morphs include albino, anerythristic, snow (albino + anerythristic), tangerine, and various pattern mutations. Normal/wild-type specimens display classic tricolor banding. Regional subspecies show natural variation in coloration and pattern.
