HELP!!! Turkish House Gecko Found

[NatureLady]

First off, we don't have these native in our area. They are only found in 3-4 counties in the entire state (released by a few universities in the 60's to control insects), but my niece found one at AMC 20 movies. To top it off it is a fresh hatchling. Of course she messaged me about it and I told her NOT to release it. Now I need help caring for it. I just purchased her a leopard gecko and the entire set up...would this little one be close in care requirements? I just ordered a fruit fly culture from Joshs Frogs and they are on he way. Any idea's as to what I can feed it until they arrive? I have contacted my biologist friend who works for the state's agency to report the finding. It really worries me that this little guy is here and I can only fear the worst. Any and all help on the needs of this little guy would be helpful. Oh, he is 1-1.5 inches in length!
