Question: I am having a problem with geckoes - I know they can't harm me but I am really afraid of them and don't want to think about them being in my house. I know they are good because they eat bugs - but I prefer they stay outside. How can I keep them out of my house?

ANSWER  Geckoes are common in houses and buildings that are surrounded by vegetation especially homes that have shaded yards. They are pests simply by their presence indoors. They do not live in or infest houses, but come in from surrounding vegetation to find insects (food).
 
Usually they are following the insects that are attracted to outdoor lights. Lights often attract moths and many other insects. Of course, geckoes don't bite people or animals, and would eventually move out of the house, unless they get lost indoors.
 
The best control strategy is to keep them out by keeping doors and windows closed or screened. Replace missing or damaged weather-stripping. Reducing the vegetation around the house and limiting outdoor lights at night may also be helpful.
