Ranch Style House

HELP?! I am so sick of geckos!we live in an old ranch style house with a crawl space how can I get rid of them

I hate having to kill things as a solution but I have a huge! phobia and dislike for these geckos. And I honestly just want them gone! If anyone can help me please do!! I also herd moth balls would work??

Pest Control company. but before you do that know that geckos eat insects. So if you kill the geckos then you will have worse problems like termites and ants and spiders.
