A Western Diamondback rattlesnake, previously undocumented in Denton County, was discovered in an Argyle resident’s garage. This significant finding marks the first official record of this species in the area and is expected to provide valuable data for scientists studying rattlesnake distribution and habitat. The snake has been safely relocated to the University of Texas at Arlington for research purposes, highlighting its unexpected presence in a region typically absent of the species.


First Western Diamondback Rattlesnake Documented in Denton County, Texas

Denton County, Texas – A Western Diamondback rattlesnake, a species previously undocumented in Denton County, was discovered in an Argyle resident’s garage on November 6, 2025. This marks the first official record of the species in the area.

Discovery Details

Rob Boles, a local wildlife handler known as a “snake whisperer,” responded to a call from an Argyle resident who believed a rattlesnake had entered her garage. Expecting to find a harmless bullsnake, Boles instead encountered a 3.5-foot adult female Western Diamondback rattlesnake. The snake’s distinctive markings—a bold white-edged diamond pattern along its back, a black-and-white banded tail, and a fully developed rattle—confirmed its identity.

Scientific Significance

The specimen was safely removed and transferred to the University of Texas at Arlington’s Amphibian and Reptile Diversity Research Center, where it became part of a research collection that includes nearly 600 Western Diamondback specimens, primarily from Texas counties south and west of Denton. This discovery fills a significant gap in the species’ documented range and provides valuable data for herpetologists studying the distribution and habitat requirements of the Western Diamondback rattlesnake.

Background on the Species

Western Diamondback rattlesnakes are the most common and widespread venomous snakes in Texas, found in all but the easternmost parts of the state. Their presence in Denton County is unexpected, as they typically inhabit desert regions, making their appearance in forested areas of the Dallas-Fort Worth region rare. Researchers believe this individual may indicate a small, previously undetected local population rather than migration from neighboring desert regions.

Implications for Local Residents

Residents are advised to exercise caution and contact wildlife professionals if they encounter snakes indoors. Responsible handling can lead to discoveries with lasting scientific value, as specimens like this one contribute to our understanding of species distribution and ecology.
