Rattlesnake Awareness and Safety
If you are concerned about rattlesnakes, it helps to know what to do when you may be in an area that is known to be populated by them. If you have knowledge on hand, you can avoid potentially dangerous encounters and respond in the instance that an attack does occur. There are a few key steps to rattlesnake safety, they include:
1. Look ahead
Always keep your eyes ahead of you, rather than where you’re stepping. Rattlesnakes blend into their environment quite seamlessly, so it won’t be easy to spot them. Look out for dark, oval shaped patterns on the path that you are walking on to ensure that snakes don’t catch you off guard.
2. Keep your distance
If you are seen by a rattlesnake, give it as much space as possible. Rattlesnakes are very sensitive to vibrations, so it will feel your footsteps as you approach and become more on-guard and aggressive. By keeping yourself at a distance, you limit the snake’s ability to reach you, making the encounter as safe as possible.
3. Stay calm
Rattlesnakes see humans as a danger, so its best to stay calm when around them. Quick movements may startle the snake, so you want to avoid reacting dramatically to a snake encounter. The best course of action is to calmly back away from the area the snake is in or choose a new route.

How To React To Rattlesnake Bites
While there is a chance that a rattlesnake bite won’t be venomous, you should still seek medical attention immediately if you are bitten. Do not attempt to suck out the venom, as this could cause complications throughout the area where the snake bit you. You also shouldn’t cut the wounded area or wash the wound, as venom from your skin can be used to identify which type of anti-venom is needed to help you.
You should also do your best to keep the affected area below your chest to keep the venom from reaching your heart too quickly. To this same end, you should remain as still as possible to minimize the flow of the venom to your heart. Staying calm helps too, as remaining calm will keep your heart rate low.
