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.

Select from:
A). 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.;
B). If possible, move your potted plants, such as flowering plants or tree branches, away from the eggshells to increase their likelihood of keeping geckos off your property. This eliminates the infestation of the house geckos: they won't see them.;
C). Using a plastic container, place 6 eggs and 0.5 tbsp (22.6 ml) of water. Boil these for 15-20 minutes, until you need enough so that they set.;
D). If your house is large enough, you can install some traps in side-spaced locations. Place tape around your exterior windows to deter flies from hanging up there.;
The answer is:
A).
