I hate seeing wall geckos around me, however, the most important question I have is if they are dangerous or poisonous in any way.

The common house gecko is not poisonous. If you look into a gecko’s mouth, you may also notice that they do not have sharp teeth, or any teeth at all. So no, they cannot hurt you.
Most geckos are nocturnal, hiding during the day and foraging for insects at night. They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights, and are immediately recognisable by their characteristic chirping. They grow to a length of between 7.5–15 cm (3–6 in), and live for about 5 years. These small geckos are non-venomous and not harmful to humans. Most medium-sized to large geckos are docile, but may bite if distressed, which can pierce skin. A tropical gecko, Hemidactylus frenatus thrives in warm, humid areas where it can crawl around on rotting wood in search of the insects it eats, as well as within urban landscapes
