Are Cockroaches Safe for Lizards to Eat?

One of the main concerns of lizard owners is whether or not the insects they feed their pets are safe. Cockroaches are a common prey item for lizards, but are they safe for them to eat?

According to PestWeek, cockroaches are safe for lizards to eat because they do not sting and their bites are not deadly.

In fact, baby lizards can even eat little roaches as long as they can fit in their mouths.

It is important to note that cockroaches in their natural form do not contain any poison and it is safe for lizards to eat them in plenty.

However, it is important to ensure that the cockroaches are not contaminated with any pesticides or chemicals that could harm the lizards.

It is also important to consider the size of the cockroaches being fed to the lizards.

Larger cockroaches may be difficult for smaller lizards to consume, which could lead to choking or other health issues. It is recommended to feed appropriately sized prey items to ensure the safety of the lizard.

Overall, cockroaches are a safe and nutritious food source for lizards.

As long as they are not contaminated with any harmful substances and are appropriately sized, they can be a great addition to a lizard’s diet.

How Do Lizards Hunt Cockroaches

Some species of lizards are also able to climb walls and ceilings, which makes them particularly effective at hunting cockroaches in hard-to-reach places.
These lizards are able to use their sticky toes to climb up walls and ceilings and then pounce on their prey from above.

Types of Cockroaches Lizards Eat

When it comes to feeding your pet lizard, you might be curious about which types of cockroaches are safe and nutritious options. In this section, you will learn about some popular types of cockroaches that are ideal for lizards to eat.

Firstly, the Discoid Roach (Blaberus discoidalis), also known as the False Death’s Head Cockroach, is a popular choice for many reptile owners. These roaches are quite hardy, provide ample nutrition, and have a high moisture content that helps prevent dehydration. Discoid Roaches can grow up to 2 inches as adults, offering a good range of sizes for different lizard species.

Another common option is the Brown-Banded Roach. These roaches are smaller and generally easier for smaller lizards to digest. Oriental and German Cockroaches are additional varieties that can be included in your lizard’s diet, providing necessary nutrients and proteins.

Red Runner Roaches are another fantastic choice, offering your pet reptile a good balance of nutrients and an ideal size for snacking. Like the other types mentioned, these roaches are bred specifically for the purpose of feeding captive reptiles and should never be confused with pest roaches located in or around your home.

To recap, here are the most popular types of cockroaches for your lizard’s diet:

  • Discoid Roach (Blaberus discoidalis)
  • Brown-Banded Roach
  • Oriental Cockroach
  • German Cockroach
  • Red Runner Roach

Always ensure that the cockroaches you provide your pet lizard come from a reliable and safe source. This helps to guarantee a healthy and balanced diet, allowing your lizard to thrive and maintain its overall well-being.

Do Lizards Eat Dead Cockroaches?

When it comes to feeding your pet lizard, you might wonder if dead cockroaches are a suitable option. While lizards do eat cockroaches, they generally prefer live prey over dead insects. However, let’s dive into the topic to help you understand the reasons and exceptions to this preference.

Live cockroaches provide not only a tasty meal but also a stimulating hunting experience for your lizard. Catching prey allows them to exercise their natural instincts, making them more active and healthy. Offering dead cockroaches may not provide the same level of enrichment for your pet.

There are also a few health concerns to consider. Dead roaches that have been lying around for a while can become tasteless and full of germs, which could be harmful to your lizard’s health. As a responsible pet owner, you want to ensure that your lizard consumes fresh, nutritious meals to keep them healthy and thriving.

That being said, there might be situations where you need to offer dead prey temporarily. For instance, if you’re unable to find live roaches, or your lizard is recovering from an injury and needs a less challenging meal. In these cases, you can consider using pre-killed cockroaches that have been preserved in a sanitary manner, such as frozen or canned insects available at pet stores.

When feeding dead cockroaches to your lizard, try the following tips to increase their appeal:

  • Warm them up slightly to mimic the body temperature of live prey.
  • Use tongs to wiggle and move the dead insect to imitate a living creature.
  • Ensure the dead roaches are from a reputable source and have not been treated with pesticides or exposed to harmful substances.

In summary, while lizards generally prefer live cockroaches, there may be instances where dead prey is needed. To provide the best care for your pet lizard, always prioritize their nutritional needs and monitor their feeding habits carefully.


It is clear that lizards do eat cockroaches, and they do so for good reason. Cockroaches provide lizards with a high protein and vitamin-rich meal that can be beneficial to their health. This is especially true for wild lizards, who cannot afford to be picky about their meals.

While captive-bred lizards may have different dietary needs, many still enjoy a diet that includes cockroaches. In fact, some species of lizards have even evolved to be particularly suited to hunting and consuming cockroaches as their primary source of food.

Just Remember, while cockroaches are a popular food source for lizards, they should be served in combination with several other insects and worms. This is because a diet consisting solely of cockroaches may not provide all the necessary nutrients for a lizard’s overall health and well-being.

For those who are looking to control pest populations in their homes, keeping a house lizard or gecko as a pet can be an effective solution. These natural predators of insects, including cockroaches, can help keep your home free of unwanted pests.
