If you have ever tried to pick up a house lizard before, then you’ll know it can bite if you put your finger around its mouth. This is a common defense mechanism that pretty much every lizard is equipped with. It kind of makes them like wild mammals in a way because they both bite to fight their enemies. Of course, house lizards are much smaller and do not appear to be as threatening to humans. But since they can bite humans, a lot of people wonder whether house lizards have any teeth or not?

The answer is yes, house lizards have teeth. How else would they be able to bite you in the first place? If they didn’t have teeth, there would not be anything sharp in their mouth to latch onto you with. So yes, house lizards have teeth because it allows them to bite in self-defense. The average house lizard has about 100 teeth in their mouth. Each tooth is replaced by another tooth every 4 months or so.

If you were to look at the mouth of a house lizard, you might have trouble seeing their teeth if you are farsighted. Their teeth are very small which is why a lot of people don’t see them. But despite the small size of their teeth, they are very sharp and can penetrate through the skin easily. This is how they’re able to hang onto your skin by their mouths after they bite you. The best thing you can do in this situation is gently force open their mouth with your other hand and toss them onto the ground. Try not to pull too hard on them while they’re biting you because it will just cause you more pain and irritation.


House lizards have blood just like any other reptile or mammal. The purpose of blood is to deliver nutrients to the cells and organs of the body. House lizards depend on blood to serve this purpose after eating bugs to survive. The color of a house lizard’s blood will usually be green. If you were to crush or stomp on a house lizard with your foot, then you would see the blood come out. Of course, you should not harm a house lizard because they pose no harm to you. If the blood happens to get on your skin, it will not hurt you. Just wash that area of your skin with soap and warm water.

Fortunately, house lizards are not poisonous and pose no threat to humans. In fact, if they were to bite your skin, it would only leave a small bite mark. There would be no other symptoms like swelling, extreme redness, itching, burning, or anything like that. Those would be symptoms of a toxic bite from poison. But since house lizards don’t have poison, they don’t transmit anything toxic to your skin if they bite you. Therefore, you do not need to be afraid to pick one up with your hands.

Although house lizards are not poisonous, they do carry bacteria in their mouths. Salmonella is a common bacterium which can infect your intestines and give you food poisoning symptoms. The salmonella can be transferred through a house lizard bite if it penetrates your skin. There is also the risk of house lizards scratching you too, which can cause Salmonella to be transferred. In extreme cases, the waste of a house lizard can be contaminated with the bacteria.
