Safety Tips for Dangerous Snakes & Spiders in Nevada

Nevada is home to a diverse variety of wildlife, including a few species of venomous snakes and spiders. While the bites of these snakes and spiders may be painful, the vast majority are not fatal when treated properly. Learning about dangerous snakes and spiders in Nevada allows you to avoid encounters and minimize harm in the event of a bite.

  1. Types

    • The arid, rocky landscape of Nevada is an ideal habitat for reptiles such as snakes. According to the University of Nevada Cooperative Extension, only five venomous snake species have been identified in Nevada. These include the Speckled, Sidewinder, Western Diamondback, Mohave and Great Basin rattlesnakes. Three venomous spider species--including the Desert Recluse, Western Black Widow and Brown Widow--have been identified in Nevada, according to Venombyte.com.

    Identification

    • Being able to identify dangerous snakes and spiders is important for avoiding encounters and treating bites. Most Nevada rattlesnakes are between 1.5 and 4 feet in length and have broader heads than non-venomous snakes. While rattlesnakes sometimes use their rattles when agitated, they do not always do so before striking. Among the spiders, both Brown and Black widows have an hourglass marking on their abdomens, though it may range in color from yellow to red depending on the species. The Desert Recluse is yellow to tan in color and lacks the violin pattern seen on the Brown Recluse spider. All recluse species have six eyes instead of eight like most other spiders. Eyes are grouped in three separate pairs across the head instead of rows of four, further distinguishing the recluse from other U.S. spiders.

    Preventing Bites

    • Avoiding contact with venomous spiders and snakes is the best prevention against bites. When venturing into the outdoors, stay on designated trails while avoiding dark, secluded spots such as bushes and rocks where snakes dwell. Wearing thick protective boots and carrying a walking stick may offer further protection in the event of a snake encounter. If you come into contact with a snake, avoid shooing it away or making other sudden moves toward it. Always take a buddy with you when camping or engaging in other outdoor activities where snakes could be lurking. To prevent spider bites, avoid disturbing spider webs and shake out old blankets and other stored items before use.

    Treatment

    • If you've been bitten by a venomous spider or snake, seek immediate medical attention. Instead of attempting first aid, call for help or drive to the nearest hospital to obtain treatment. Only attempt to identify the snake or spider if you can do so quickly and without risking further injury. When used correctly, a snake bite kit may offer increased protection against snake venom, though more research is needed in this area.
