Cockroaches are notorious for being able to survive in almost any environment. They are attracted to moist and warm environments, but they can also live in dry areas. One of the things that make cockroaches so adaptable is their ability to eat almost anything. In this article, we will explore what cockroaches eat and how you can prevent them from infesting your home.

What Do Cockroaches Eat?

Cockroaches are omnivores, which means they eat both plants and animals. They will eat anything that is organic and contains nutrients such as carbohydrates, protein, and fat. Some of the most common things that cockroaches eat include:

  • Sugar: Cockroaches have a sweet tooth and will eat anything that contains sugar. This includes fruits, sugary beverages, and even sweets left out on the counter.

  • Protein: Cockroaches need protein to survive, and they will eat anything that contains it. This includes meat, fish, cheese, and eggs.
