Do lizards bite?

Some do. I've been bitten by tokay geckos. Komodo monitors are predators and bite. So do the Gila monster and Mexican beaded lizard.

Komodo dragons are the largest lizards in the world and are killers, they have a saliva in there mouths that when they bite you it causes blood poisoning.

Lizard bite is very infrequent in children. ... Bites are only inflicted when they are manipulated or when they are cornered and feel threatened. Lizard bites may be frightening but most do not cause serious health problems. The wall lizard or gecko, found in most homes, is not poisonous at all.

Yes. All lizards can and will bite. You can try to prevent it by proper handling (assuming the lizard is a pet such as a leopard gecko) but even then they can still bite. If you're asking if wild lizards bite when being held they most certainly will, even more so than tame geckos. 

yes, they can and they WILL.

I feel like anything with a mouth can bite.

He's the basic house gecko, a.k.a. the Mediterranean gecko. They are wherever on the planet that is sufficiently warm to allow them to endure winter.

In the event that you get him, and on the off chance that he can discover a piece of your hand adequately little to fit in his mouth, he may attempt to tear into you, however I question you'd feel it. They don't have teeth.

All the more critically, you would prefer not to dispose of them. In the event that they're there, this is on the grounds that there's food there. Nourishment for them is little bugs, similar to gnats, flies, insects, silverfish, cockroaches, and so forth They can eat at least twelve of these bugs each day. Consider that briefly and lets do some math.

1 gecko x 12 creepy crawlies a day = 4380 bugs for each year.

In the event that you see one gecko, there are likely at any rate twelve you don't see, stowing away in the dividers, under the floor, in the upper room, and so on 12 x 4380 = 52,560

Thus, in a year that is 50,000 bugs in your home without any hunters to eat them!

Kind of depends on what kind of lizard.
