I believe that is a good sign because where there's snakes there's bugs and critters and such and they wouldn't be there if it wasn't a pleasant place to hang out. The probably feed mostly on rolly pollies. For every snake I've found I've found hundreds of rolly pollies.

Don't mind the mess. One day this will be a greenhouse with actual plants everywhere instead of wood and stuff. Oooh look! You can see some small pots on the bottom left by the light! It's proof...
