    These small, wiggly creatures are a favorite snack for many lizard species. They are high in protein and can be easily obtained from pet stores or online suppliers.
  • Waxworms:
    A delicious treat for lizards, waxworms are high in fat and can provide a good boost of energy.

Foods to Avoid Feeding Lizards

While it’s essential to provide a diverse diet for your lizard, certain foods should be avoided. Here are some examples:

  • Toxic Plants:
    Some plants, such as lilies, are toxic to lizards and can cause severe health issues or even be fatal. Make sure to research the toxicity of plants before introducing them into your lizard’s habitat.
  • Insects Caught in the Wild:
    Insects caught in the wild may carry pesticides or parasites that can harm your lizard. It’s best to provide commercially bred insects or ones you have raised yourself.
  • Processed or Sugary Foods:
    Lizards have specific dietary requirements and processed or sugary foods are not suitable for them. Stick to natural, whole foods to ensure their health and well-being.


Do Lizards Drink Water?

Water is essential to the survival of all forms of life, including lizards. While lizards can get some of the water they need from their meal, it is still important to offer a water source.

Provide them with fresh water in a small dish and replace it frequently. Misting lizards with water could be relaxing for them because it’s similar to the humidity they’d find in their natural habitat.

If you’re dealing with a cockroach infestation and want to tackle it naturally, lizards can be a helpful ally. However, it’s important to create a safe and comfortable environment for both your lizard and yourself. Here are some natural ways to get rid of cockroaches:

  • Keep a Clean Environment:
    Cockroaches are attracted to food crumbs and dirty spaces. Regularly clean your home, especially the kitchen, to minimize their attraction.
  • Seal Cracks and Entry Points:
    Prevent cockroaches from entering your home by sealing cracks and crevices. Check the areas around the doors, windows, and pipes thoroughly.
  • Use Natural Repellents:
    Natural repellents such as peppermint oil, bay leaves, and cucumber peels can deter cockroaches without harming your lizard.
  • Employ Lizard-Friendly Strategies:
    Provide lizards with places to hide, like small rocks or nooks, and they’ll feel more at home in your house. This will make it easier for them to hunt down and feast on the local cockroach population.
