I'm a snake over-reactor. I hate to kill anything, but I'm scared of snakes being near the kids, and we just moved to a place where I don't know the wildlife (FL).
I took out what we thought was a dangerous snake a month ago, and it turned out to be a "glass lizard" - a legless lizard that eats mice, frogs, etc. It had a yellow-tipped tail. Weird, huh?
DD was so proud of me, when we thought it was a snake, but she was HORRIFIED when we found out it was a lizard! Luckily, there is another glass lizard that apparently also likes our yard.
