Are House Lizards Poisonous
If you’ve ever seen a house lizard, also called a gecko, you may have wondered if they are poisonous. The answer is no, they are not poisonous to humans. However, they can be harmful to other animals if eaten.
These lizards are found in tropical and sub-tropical regions around the world. They vary in size, but most measure less than a foot long from head to tail. House lizards are brown or gray with spots or stripes.
They have large eyes and sticky toes that help them climb walls and ceilings.
While they are not poisonous, house lizards can carry diseases that can be harmful to humans such as salmonella and toxoplasmosis. So it’s important to wash your hands after handling them or anything they’ve been on.

How to Know If a Lizard is Poisonous
There are more than 6,000 species of lizards in the world, and only a handful of those are poisonous. Most lizards pose no threat to humans whatsoever. But if you’re unlucky enough to encounter a poisonous lizard, it’s important to know how to tell if it’s dangerous.
Here are a few things to look for:
1. The majority of poisonous lizards are brightly colored. This is nature’s way of warning predators that they’re not safe to eat.
So, if you see a lizard with bright colors like red, orange or yellow, be wary.
2. Another way to tell if a lizard is poisonous is by looking at its eyes. Many poisonous lizards have vertical pupils (like a cat), while non-poisonous ones have round pupils.
3. Poisonous lizards also tend to have shorter legs in proportion to their bodies than non-poisonous ones do. This helps them move quickly so they can escape predators.
4. Finally, some poisonous lizards have toxic glands near their tails that secrete venom when the lizard feels threatened.
If you see a lizard with this type of gland, it’s best to stay away!
House Lizard Poison Treatment
If you have a house lizard infestation, there are a few things you can do to get rid of them. You can try to trap them and then release them outside, but this may not be effective if there are too many lizards or they keep coming back. Another option is to use poison, but this can be dangerous if not done correctly.
Poisonous chemicals that are commonly used to kill lizards include carbamate and organophosphate pesticides. These poisons work by inhibiting the enzyme acetylcholinesterase, which is essential for the nervous system function. This results in paralysis and death.
There are a few things to keep in mind when using these poisons. First, make sure that the area where you will be applying the poison is well ventilated so that you don’t breathe in any fumes. Second, wear gloves and protective clothing while handling the poison so that you don’t get it on your skin.
Finally, apply the poison only in areas where lizards are active; don’t put it everywhere in your home as this could be dangerous for people and pets.
If you follow these guidelines, using poison should get rid of your lizard problem safely and effectively.
