Snakes, spiders head back outside as weather warms

Warmer temperatures are bringing spiders and snakes back out into the open air of Arizona - the kind of critters that spark fear in the minds of humans.

"In a 2001 Gallup poll, 51 percent of adults cited snakes as their biggest fear, and spiders were fifth," said Zen Mocarski, public information officer for the Game and Fish Region 3 office in Kingman. "But spiders, scorpions, rattlesnakes, the Gila monster, and a variety of other critters are part of life in Arizona. As it warms up, they'll become increasingly more visible."

People who take the time to educate themselves and their children about these critters can minimize the likelihood of a dangerous encounter, Mocarski said.

Arizona is home to the most dangerous rattlesnake, spider, lizard, and scorpion in the nation. However, bites and stings aren't as common as people might believe.

Mocarski worries most about young children who have a natural curiosity of their surroundings.

"Parents need to teach children not to pick up any type of wildlife," he said. "Teach your kids to come and get you when they see something."

The most commonly encountered rattlesnake in Arizona is the western diamondback, which also accounts for the most bites. While there is no such thing as a typical rattlesnake bite, the Mohave is accepted as the most dangerous, although the potency of its venom can vary from region-to-region.

"What's the most dangerous rattlesnake?" Mocarski asked. "The one that bit you."

Accidental bites are rare and many incidents involve alcohol, Mocarski said. However, if bitten, the rules to follow are simple.

"Remove any restrictive clothing and jewelry and get to a medical facility as quickly as possible," he explained. "Forget what you've seen in movies and get treatment with anti-venom.

"Do not cut open the bite area and try to suck out the venom, don't submerge the bite area in ice, and do not tie off the area with a tourniquet."

While approximately 30 percent of rattlesnake bites are considered dry bites - those that do not require anti-venom treatment - a medical professional should make that determination.

In addition, do not spend time trying to capture or collect the rattlesnake. Identification is not necessary for treatment.

Understanding wildlife behavior can go a long way in avoiding bites and stings.

Rattlesnakes are cold blooded and have to work to maintain an ideal body temperature. During cooler times, such as evening hours, rattlesnakes will seek out a heat source such as pavement. During the heat of the day, they will seek shade.

It is a myth that rattlers always will rattle before a strike, Mocarski added.

"It's our jobs to take certain precautions," Mocarski said. "Keep a close eye on the sides of trails, and never place your hands and feet in an area you can't see."

As for dogs, Mocarski said encounters with rattlesnakes can be dangerous.

"Dogs tend to be bitten around the face and neck," he explained. "Training can help, but keeping your pet on a leash and close to your side will help avoid bites that occur as a result of a dog's natural curiosity."

Mocarski advises people to wear gloves when working around wood or rock piles, and to shake out shoes that have been left outside, in case scorpions and spiders get into them.

Most scorpion stings are comparable to that of a bee. However, the sting of the bark scorpion can be more severe. Its sting can be harmful to young children, the elderly, and individuals in poor health.

"People need to remember that everyone reacts differently to venom," Mocarski explained. "Pay attention to how your body is reacting. If someone is having trouble breathing, slurred speech, or nausea following a bite or sting, they should probably seek medical attention."

While all spiders are venomous, two factors must exist to be considered a threat to humans: the venom must be strong enough to do damage and their jaws must be able to break human skin.

With these factors in mind, two spiders in the area are considered dangerous to humans: the brown (a relative of the brown recluse), and the black widow.

The Gila monster is the only dangerous lizard in North America. Its bite is extremely painful and can result in vomiting and convulsions. The Gila monster also is notorious for not letting go, and victims have been known to show up at an emergency room with the lizard still attached.

"A Gila monster bite is not something an individual wants to experience," Mocarski said. "The good news is that if people leave them alone, they'll leave the people alone. I've never heard of an accidental Gila monster bite."

The Gila monster is protected and it is illegal to disturb, capture, or kill one, Mocarski added. It is rarely seen, spending much of its life underground.

"All these animals are important parts of the ecosystem," Mocarski explained. "Rattlesnakes help keep rodent populations under control while scorpions and spiders feast on a number of different types of insects.

"They've been here a long time. It's our job to learn to live with them, not their job to learn to live with us."
