Will Rat Poison Kill Iguanas?

Iguanas are a common sight in many backyards and gardens. These large lizards can be beneficial to the environment, but they can also cause problems for homeowners. One of the biggest concerns for those who have iguanas on their property is how to control their population. One popular method is using rat poison. However, the question is, will rat poison kill iguanas?

What is Rat Poison?

Rat poison, also known as rodenticide, is a toxic substance used to kill rodents. It comes in different forms, including pellets, blocks, and liquid. The active ingredients in rat poison are anticoagulants, which prevent the blood from clotting. When a rodent ingests the poison, it slowly bleeds to death over the course of several days.

Can Rat Poison Kill Iguanas?

The short answer is yes, rat poison can kill iguanas. Since iguanas are reptiles, their bodies work differently than mammals. However, just because it can kill them does not mean it is a good idea to use rat poison to control iguanas.

Rat poison can also harm other animals that may ingest it, such as pets or wildlife. It can also contaminate the environment, leading to long-term damage. Additionally, using rat poison to control iguanas does not address the root cause of the problem, which is usually an overabundance of food or shelter.

Alternatives to Rat Poison

If you have an iguana problem on your property, there are other methods you can use to control their population. One option is to remove any potential food sources, such as fruit trees or vegetable gardens. You can also make your property less hospitable to iguanas by removing any shelter, such as piles of debris or overgrown vegetation.

Another option is to use physical barriers to keep iguanas out of certain areas. This can include erecting fences or using netting to cover plants. You can also use humane traps to capture iguanas and release them in a more suitable location.

The Benefits of Using Alternatives

Using alternatives to rat poison has several benefits. First, it is safer for other animals and the environment. Second, it addresses the root cause of the iguana problem, rather than just the symptoms. Finally, it can be more effective in the long run, as iguanas may eventually develop a resistance to rat poison.

Rat Poison vs Alternatives

When comparing rat poison to alternatives, it is clear that the latter is the better option. Rat poison is dangerous and can harm other animals and the environment. It also does not address the root cause of the problem. Alternatives, on the other hand, are safer and more effective in the long run.


In conclusion, while rat poison can kill iguanas, it is not the best method for controlling their population. Using alternatives, such as removing food sources, using physical barriers, and humane traps, is a safer and more effective option. By taking a proactive approach to iguana control, you can create a safer and more enjoyable environment for yourself and all the creatures that share your space.
