California note
Rattlesnake season is mostly about space and attention
Give rattlesnakes room; if someone is bitten, call 911 and do not use ice, cutting, suction, or a tourniquet.
Rattlesnakes are part of California life in many warm, dry, rocky, grassy, and foothill places. Most people will never have a problem if they give snakes room and stay aware on trails and around yards.
The simple habit is to look before reaching, stepping, or moving things. Watch around rocks, brush, woodpiles, tall grass, garages, and shaded edges on hot days. Keep dogs close on trails, and teach kids not to poke or pick up any snake.
If you see one, back away and let it move on. If a snake is where people or pets cannot safely avoid it, use local animal control or qualified help.
If someone is bitten, call 911 and get to a hospital. Keep the person calm. Do not apply ice or heat, cut the bite, try to suck out venom, or use a tourniquet. California Poison Control can give additional guidance at 1-800-222-1222 after emergency help is on the way.
