PHOENIX (KSAZ) - If you hear a rattle on Halloween night, just know it might not be a prop to scare you.
"We need to be very careful when we have the little ones out and about tonight, running around, collecting candy and stuff like that," Daniel Marchand said.
Marchand is with the Phoenix Herpetological Society and says rattlesnakes are out in bigger numbers right now because of the lingering heat into this season.
"So, you have to pay attention to where you are putting your hands and feet at all times, making sure you're not getting yourself in trouble," he said.
Most of the rattlesnakes come out during the heat of the day.
"As the Sun comes up and warms up during the day, the temps are perfect for them and between 80 and 90 degrees, that's when they're most comfortable to come out and do what they do," Marchand said.
Marchand says trick-or-treaters need to make sure they are paying attention when going from door-to-door and to especially pay attention to anything slithering behind decorations.
"Decorations here, the rattlesnakes could be just hiding right amongst the decorations among your front door," he said.
