Should've kept reading.... It states a few sentences down that at night the stick out like a sore thumb but during the day they are hard to spot since they can hind behind branches.
Anyways, glad to see this is getting some sort of spotlight. When I lived in Florida, I would go out at night looking to catch them and pythons. Every now and then I would find one, mostly veileds, and bring it to a local zoo for them to take in since I didn't have the means to care for them back then. All I knew back then was that they were invasive and should be removed when found.
