What Do Cockroaches Usually Eat?
Cockroaches are not very picky eaters. They eat almost anything. Here are some things cockroaches like to eat:
- Food crumbs and leftovers
- Grease and oils
- Paper and glue
- Dead insects
- Starch from books or wallpaper
- Soap and toothpaste
Cockroaches can even survive for weeks without food. They only need water to live longer. Their strong mouthparts help them chew many materials.
Do Cockroaches Eat Hair?
Now, the big question: do cockroaches eat hair? The short answer is yes, but only under certain conditions. Let’s explain this carefully.
Hair is made of keratin. Keratin is a tough protein. Most insects find it hard to eat keratin. Cockroaches don’t usually eat fresh, clean hair. But they might eat hair if it is dirty or mixed with other food.
For example, if hair is on dirty floors or in trash, cockroaches might chew it. They do this because the hair has bits of food or grease on it. This makes the hair easier and tastier for them to eat.
Also, cockroaches sometimes eat shed hair. People lose hair daily. This hair can fall on the floor or in corners. If the hair is old and dirty, cockroaches may nibble on it.
In short, cockroaches do not hunt for hair. Hair is not their favorite food. But they will eat hair if it helps them survive or if it has other food on it.

Why Do Cockroaches Eat Hair Sometimes?
Cockroaches are scavengers. This means they eat what they find. If food is scarce, they try to eat unusual things. Hair might become a food source when nothing else is available.
Hair can also provide some nutrients. It contains small amounts of protein. In harsh conditions, cockroaches use every resource. This helps them stay alive.
Another reason cockroaches eat hair is because it helps them build nests. Cockroaches sometimes use hair strands to make their homes. The hair can hold moisture and keep the nest safe.
