You can now add the Komodo dragon to your list of poisonious lizards, so, now there are three of them in the world. Except that komodo dragons are not venomous they have deadly bacteria in their saliva but have no venom glands to speak of. So the count remains two.

Are house lizard poisonous?

No. The two most venomous species of lizards are the Gila Monster and Beaded lizard, which are closely related. Monitor lizards also have a mild venom, as do a few agamids, but no geckos are venomous. Bites from animals other than the Gila Monster, Beaded Lizard, and Komodo Dragon are considered harmless, as the venom produced by other species is too mild to cause anything more than a little localized swelling. Venomous animals inject or introduce toxins through their bite. Poisonous animals are toxic if eaten. Poisonous lizards are extremely rare (only a couple of species have been found), and no geckos are poisonous, either. Most lizards that are found in homes are geckos or anoles, both of which are completely harmless. They can carry parasites, however, so you should not let your cat or dog eat them.
