How do I get rid of Blue Tailed Skinks?

Question:They are all over my house. Do they carry diseases ?

Answers:
Kill every single insect in your house. If they can't get food, they'll move on. Of course, since skinks don't carry any transmittable diseases (and insects do), why would you want to get rid of them? I have a home overseas and we have lots of geckos (everywhere). They don't bother me and we don't bother them.
I suppose if I wanted to get rid of the lizards, I could always find a snake or bird (or filthy, disgusting rat for that matter) that would eat them.
On a side note, I have spiders in my house in America. Live and let live (within reason, no brown recluse or black widows, etc) Should I spray poison to kill them (and my family) or chill and let them do what nature designed them for?
