I live in Arizona. These have been coming out in the evening. They are 1-2β long and looking like really skinny earthworms. I took it to the local pest supply store and they had never seen anything like it.
Update: my pest control company had never seen anything like it. They sent some examples to ASU to identify. Turns out they are a type of millipede. Very uncommon in this region.
Looks to me like a juvenile Texas Blind Snake. Iβm no reptile expert though, canβt tell for sure
