When I took the photograph of this lizard, he was looking at me. I often see them in home. However they never attack us. They only eat insects. They take cockroach head inside their mouth and swallow gradually. I have heard that they can be poisonous. To know the fact, I searched on google and read an article which claimed that home lizards are not poisonous. They only consume insects to reduce their population.
