Poison control officials are warning people who work and play outdoors to be aware of baby rattlesnakes.

The baby rattlers are primarily born in July and August and range in length from 6 to 12 inches, according to a news release from the UA.

The baby snakes do not have rattlers and can strike without making noise, according to the Arizona Poison and Drug Information Center. The baby snakes have enough venom to be dangerous and often hide in tall grass and brush.

The poison information center, part of the University of Arizona's College of Pharmacy, has received 74 reports of rattlesnake bites of humans this year through July 31. The center handles all calls in Arizona except for Maricopa County.

Some people calling don't realize they've been bitten by a snake, experts say. Anyone outside who experiences a sting, pinch or bite, especially to an arm or leg, can call the center at 1-800-222-1222. Experts taking the call can ask questions to help determine if a person suffered a snake bite.
