If you live in southwestern utah, the banded gecko species that you have is the Utah Banded Gecko (Coleonyx variegatus utahensis). Banded geckos can be found under rocks and debris. I think that it is easier to find them at night, when they are active. Check on roads that go through habitat. Hope that helps! Also remember that the Utah Banded Gecko is a controlled species and you are only allowed 4 individuals at any given time.
