Do geckos bite

Geckos will bite you if you make them mad. For example, a gecko doesn't like it if you pet them under their chin, of you do that for a while they will bite you. being bit by a gecko doesn't hurt, it feels like someone is squeezing your finger, not even a pinch, a squeeze.

no they are very harmless

it takes a LOT of provoking to make a gecko bite
