Hi there, pet lovers! š
For reptile enthusiasts looking for a striking, arboreal snake thatās venomous but manageable, the Baronās Racer (Philodryas baroni)* is a fascinating choice. Known for its vibrant green or blue coloration, long prehensile tail, and mild venom, this South American species offers a unique middle ground between harmless colubrids and highly venomous snakes.
But is it the right pet for you? In this detailed review, weāll cover everything from temperament and handling to enclosure setup, feeding, and legal considerations. Whether you’re an experienced keeper or just curious about this beautiful species, this guide will help you decide if the Baronās Racer belongs in your collection.
Overview
The Baronās Racer is a large, arboreal colubrid native to Argentina, Bolivia, and Paraguay. While venomous, its bite is not medically significant for most people, making it a safer choice than true vipers or elapids. Hereās a quick summary of what makes this snake special:
- Handling & Temperament: Generally docile but can be flighty; bites are rare and mild.
- Care & Maintenance: Moderateārequires climbing space, humidity, and proper heating.
- Health & Durability: Hardy and long-lived (10+ years) if kept in optimal conditions.
- Availability: Uncommon but obtainable from specialty breeders.
- Cost: Mid-range for exotic snakes; setup costs are reasonable.
- Overall: A great choice for experienced keepers who want a venomous-like snake without extreme risk.

Why Choose a Baronās Racer?
For those who love arboreal snakes with striking colors, the Baronās Racer is a jaw-dropping alternative to green tree pythons or emerald tree boas. Unlike more delicate species, itās adaptable, hardy, and feeds readily on rodentsāthough it will also eat lizards and birds.
Its mild venom (comparable to a hognose or false water cobra) makes it a low-risk option for keepers comfortable with rear-fanged species. Plus, its active, inquisitive nature makes it a more engaging pet than many sedentary snakes.
Handling and Temperament
Personality Variations
Baronās Racers are nervous as juveniles but often calm down with age. While some remain skittish and quick-moving, others become curious and tolerant of handling. Unlike true “racers,” they are not prone to biting defensivelyāmost strikes are feeding responses.
Handling Tips
- Support their bodyāthey are lightweight but fast, so avoid sudden movements.
- Avoid grabbing near the headāthis can trigger a defensive reaction.
- Watch for tail vibrationsāa sign of stress (though they rarely musk).
- Supervise beginnersāwhile not dangerous, their speed can lead to escape attempts.
Venom & Bite Risk
Their venom is weak compared to vipers or cobras, causing mild swelling and discomfort (similar to a bee sting). No confirmed severe reactions exist, but allergies are possible. Most bites occur during feeding or accidental hand confusionāso use tongs when offering food.

Care and Maintenance
Enclosure Setup
- Size: Minimum 4x2x3ft (LxWxH) for adultsāthey need vertical space.

Feeding
- Diet: Primarily frozen-thawed rodents (mice/rats). Some may take lizards or chicks.
- Frequency: Every 7-10 days for adults, 5-7 days for juveniles.
- Tip: If a juvenile refuses rodents, try scenting with lizard smell.
Lighting
- UVB Optional but Beneficial: Helps with metabolism and natural behavior.
- Day/Night Cycle: 12 hours light, 12 hours dark.
Health and Durability
Common Health Issues
- Dehydration: Low humidity can cause stuck shed.
