I love everything about Colorado! From the mountains, to the plains, to the Front Range–there is so much to see and do! Okay, wait…maybe I don’t love everything about Colorado. Now that I think about it, I’ve seen some of the creepiest creepy crawlies in both the mountains and on the plains a time or two. Yuck!! Just who are these neighboring pests? Let’s find out together as we explore 12 of the creepiest crawlies in Colorado.
