The City of Vacaville is asking residents to be aware that late spring and early summer are times of high activity for rattlesnakes in our area. In recent years some residents - as well as their pets - have been bitten by rattlesnakes. 

According to the California Department of Fish and Wildlife, rattlesnakes, while generally not aggressive, strike when threatened or deliberately provoked, but given room they will retreat. Most snake bites occur when a rattlesnake is handled or accidentally touched by someone walking or climbing. The majority of snakebites occur on the hands, feet and ankles.

Rattlesnakes can cause serious injury to humans on rare occasions. The California Poison Control Center notes that rattlesnakes account for more than 800 bites each year with one to two deaths. Most bites occur between the months of April and October when snakes and humans are most active outdoors. About 25 percent of the bites are “dry,” meaning no venom was injected, but the bites still require medical treatment.

Rattlesnakes are not confined to rural areas. They have been found near urban areas, in river or lakeside parks, and at golf courses. Be aware that startled rattlesnakes may not rattle before striking defensively. There are several safety measures that can be taken to reduce the likelihood of startling a rattlesnake.

• Never go barefoot or wear sandals when walking through wild areas. Wear hiking boots.
• When hiking, stick to well-used trails and wear over-the-ankle boots and loose-fitting long pants. Avoid tall grass, weeds and heavy underbrush where snakes may hide during the day.
• Do not step or put your hands where you cannot see, and avoid wandering around in the dark. Step ON logs and rocks, never over them, and be especially careful when climbing rocks or gathering firewood. Check out stumps or logs before sitting down, and shake out sleeping bags before use.
• Never grab “sticks” or “branches” while swimming in lakes and rivers. Rattlesnakes can swim.
• Be careful when stepping over the doorstep as well. Snakes like to crawl along the edge of buildings where they are protected on one side.
• Never hike alone. Always have someone with you who can assist in an emergency.
• Do not handle a freshly killed snake, it can still inject venom.
• Teach children early to respect snakes and to leave them alone. Children are naturally curious and will pick up snakes.

Though uncommon, rattlesnake bites do occur, so have a plan in place for responding to any situation. Carry a portable phone, hike with a companion who can assist in an emergency, and make sure that family or friends know where you are going and when you will be checking in.

The first thing to do if bitten is to stay calm. Generally, the most serious effect of a rattlesnake bite to an adult is local tissue damage which needs to be treated. Children, because they are smaller, are in more danger if they are bitten.

Get to a doctor as soon as possible, but stay calm. Frenetic, high-speed driving places the victim at greater risk of an accident and increased heart rate. If the doctor is more than 30 minutes away, keep the bite below the heart, and then try to get to the doctor as quickly as possible.

The California Poison Control Center advises:

• Stay calm
• Wash the bite area gently with soap and water 
• Remove watches, rings, etc, which may constrict swelling
• Immobilize the affected area
• Call 911, or if possible, transport safely to the nearest medical facility
