Rattlesnake season begins in San Diego: what to know

SAN DIEGO (FOX 5/KUSI) -- Although slithering rattlesnakes can be seen year-round in Southern California, peak season for spotting them is in full effect.

According to officials with the County of San Diego Parks and Recreation, rattlesnake sightings are most common in the region from April to September. This can be attributed to gradually rising temperatures as spring turns to summer.

Although rattlesnakes are crucial for maintaining population control over rats and mice, they should be avoided by humans and pets. If bitten by these venomous and stealthy creatures, a medical emergency is sure to follow.

Those in the medical field have warned that severe and even life-threatening symptoms may occur within minutes of being bitten by a rattlesnake. This includes major bleeding, nausea and lightheadedness, drooling, as well as swelling in the mouth and throat that can then make it difficult to breathe. In rare cases, collapse and shock are even possible.

How to spot a rattlesnake

As explained by county officials, rattlesnakes are moderately easy to identify. The reptiles have large triangular heads with narrow neck. Their bodies are typically wide with a pronounced ridge running down the middle of their backs.

Another defining characteristic -- which they are named after -- is the noise they make while warning intruders of their presence. County officials advised locals to pay close attention to the sound of their rattles -- a sign that shouldn't be taken lightly.

Just this week, Mike Long came across a rattlesnake in Ramona, capturing the moment on video (below).

"Be careful while hiking! This speckled rattlesnake gave me the rattle warning. As I froze, it slowly went away from me," Long told FOX 5/KUSI.

How to prevent rattlesnake encounters

County officials, along with the San Diego Humane Society, have offered up tips for rattlesnake season. Here's a breakdown of some of those suggestions:

-- Be aware of your surroundings and remain alert: Stay on trails and actively scan the path in from of you. This is also true for backyards and residential areas. Officials say it's common for rattlesnakes to nestle in the shrubbery that lines pathways. Keep your pets close while walking them in areas that may harbor rattlesnakes.

-- Leave the rattlesnake alone: County officials said most bites happen when people try to pick up the reptile, tease it, or attempt to kill it. Typically, they will try to avoid encounters if there is an escape route available to them. It's best not to crowd their space.

-- If bitten, stay calm: Call 911 and medical attention as soon as possible. If you do not have a phone on you, county officials advised those with bites to walk at a relaxed pace until they can find help. Do not try to suck out the venom, don't apply ice and do not bandage the wound. Instead, use soap and water or an antiseptic wipe.

Safety is priority this rattlesnake season. Use your best judgment and always play it safe.
