I can't believe I have these geckos in my own yard!
They usually hide on the other side of the fence and will pop out every once in awhile. I've been trying to leave jelly out for them.
The following info is from here.
Rather than arriving as a stowaway as other geckos and skinks have, the gold dust day gecko was illegally smuggled in and released. The entire Hawaiian population stems from only eight lizards a University of Hawaiʻi student released near the Mānoa campus in 1974. Shortsighted lizard enthusiasts intentionally dispersed the geckos, which then colonized new areas on their own.
