Invite it to lounge around?
I don't have them in the house intentionally because unlike other benign cats mentioned in these lizard-related threads, my trim housecats like nothing more than to stalk and capture anything that moves. I called Howard one week asking how to keep the tarantulas away from the house--after his first response that they're beneficial, don't kill them--I explained that I knew that. I wanted to keep them outside so my cats wouldn't kill them (the calico did nail a tarantula last summer). So geckos, while they're welcome to visit briefly, are not encouraged to stay indoors. And with all of the tarantulas, geckos, native lizards, snakes, birds, and toads, few bugs manage to run that gauntlet to reach the house!
I must say that it isn't like geckos eat bugs and that's all there is to it. The porch geckos regularly duck into my mail box (one with a top that opens upward on the wall next to the front door). They spend the day in there, and greet the mailman by bursting from the box and running up the wall. And every so often I go lift it off the wall and dump out the dry gecko poop. So if they're in your cupboards and around your cabinets and furniture, you'll have to clean carefully (don't vacuum up the darlings!) and I personally would at least wash the top plate when pulling out a stack to set the table for dinner!
