Always watching where you place your hands and feet. Avoid sticking them blindly under rock edges, logs or brushy vegetation where these creatures commonly are found. Shake out your clothing, boots, or shoes before wearing. Leave your sleeping bag rolled up until you're ready to lie down, and always shake it out before getting inside. Use a flashlight at night.
Scorpions are nocturnal and very active during the summer months.
Stings are not uncommon. They are painful and while symptoms may vary in severity, they usually do not require evacuation and spontaneously improve within 24- 48 hours. Rattlesnake bites are uncommon in the Grand Canyon and those that happen are usually the result of attempted handling the snake by overly excited and uninformed visitors. Fortunately, like scorpion stings, no one has ever died from a rattlesnake bite in Grand Canyon. If a snake is causing problems in camp, let your guides know right away and let them handle the situation according to their training.
