How to get rid of common house geckos 
Place some eggshells. 
This is a very effective and inexpensive way to scare away geckos: they see eggshells and they think " predator. " leave two eggshell halves around your home, such as at outdoor entryways, or in the kitchen.
Do not crush the eggshells, leave them in two halves. One two-halves pair at every entrance should be enough: the geckos just need to run into it, then they'll run away from it.
