On March 24, 2026, a University of Colorado Boulder student discovered a small snake inside her suitcase after returning from a trip to Costa Rica. Recognizing that the animal was not native to Colorado, a local pest control company contacted Scales ‘N Tails for assistance with identification.
The snake was identified as a slender hognose pit viper, a venomous species native to parts of Central America, including Costa Rica, Guatemala, El Salvador, Honduras and Nicaragua. From there, Scales ‘N Tails contacted experts at Denver Zoo Conservation Alliance (DZCA) and Colorado Parks and Wildlife (CPW) to determine the safest and most appropriate next steps.
A Collaborative and Safe Response
When non-native wildlife is discovered, especially a venomous species, quick and coordinated action is critical to protect both people and animals.
CPW evaluated several options, including returning the snake to its native range, placement with a qualified research or education facility or euthanasia. Due to the complexities of international transport and the specialized care required, CPW and Scales ‘N Tails worked to identify a facility equipped to safely house and care for the animal.
Given DZCA’s expertise in managing venomous reptiles, our team was identified as the best fit to safely rehome this snake. On March 25, following coordination with CPW and Scales ‘N Tails, the snake was safely transferred to DZCA’s care.
Our Tropical Discovery team utilized specialized handling equipment and safety protocols to transport the snake securely to the Zoo, where it is now receiving expert care behind the scenes in Tropical Discovery.
Next Steps for this Slithery Stowaway
The young snake, believed to be just a juvenile and weighing approximately 18 grams, is currently in a quarantine. This standard process helps ensure the health and safety of both the new arrival and the animals already in our care.
Because the snake originated in the wild, quarantine allows our Animal Care and Veterinary Medicine teams time to monitor for any signs of illness or parasites and provide treatment if needed. This precautionary period is a critical step in maintaining the wellbeing of the entire animal population at DZCA.
DZCA is already home to four slender hognose pit vipers, offering the expertise and facilities needed to care for this species long term. However, decisions about the snake’s permanent placement, including whether it may eventually be visible to guests, will be made later based on its health and wellbeing.
Why This Rescue Matters
This situation highlights the importance of responsible travel and wildlife awareness. Animals can sometimes unintentionally hitch a ride in luggage or cargo, creating potentially dangerous situations far from their native habitats.
Through strong partnerships with agencies like CPW and organizations such as Scales ‘N Tails, DZCA can step in when these situations occur, providing a safe outcome for both the animal and the community. In fact, DZCA has supported several complex animal rescues including Tundra the grizzly bear, Pecan and Cashew, our leucistic raccoons, and Marshmallow, our albino red-necked wallaby.
By combining expertise in animal care, conservation and public safety, we remain committed to protecting wildlife around the world and right here in Colorado.
