What Do Cockroaches Eat?

What Do Cockroaches Eat?

Cockroaches are opportunistic scavengers, which means they'll eat almost anything they can find. While they prefer foods commonly found in kitchens, they're remarkably adaptable and can survive on many organic materials. This ability to eat a wide variety of items is one reason cockroaches are such persistent household pests.

Understanding what cockroaches eat can help you eliminate the food sources that attract them and reduce the chances of an infestation.

Human Food

Cockroaches are strongly attracted to many of the same foods we eat.

Some of their favorites include:

• Bread and crackers

• Cereal and grains

• Rice and pasta

• Fruits and vegetables

• Meat

• Cheese

• Sugary foods

• Grease and cooking oils

• Crumbs left on floors and countertops

Even small amounts of food left behind can attract cockroaches.

Pet Food

Pet food is another common food source for cockroaches.

They are often attracted to:

• Dry dog food

• Dry cat food

• Wet pet food

• Bird seed

• Small animal food

To reduce the risk of attracting cockroaches, avoid leaving pet food out overnight and store it in sealed containers.

Garbage and Food Waste

Cockroaches thrive anywhere food waste is available.

They are commonly found around:

• Kitchen trash cans

• Recycling bins

• Compost containers

• Food scraps

• Dirty dishes

• Grease buildup around appliances

Taking out the trash regularly and cleaning garbage containers can help make your home less attractive.

Non-Food Items

When food is scarce, cockroaches can survive by feeding on many other materials, including:

• Cardboard

• Paper

• Glue

• Book bindings

• Soap residue

• Toothpaste

• Leather

• Hair

• Dead insects

• Pet waste

Their ability to survive on these materials makes them especially difficult to eliminate if other food sources remain available.

How to Reduce Food Sources

Limiting access to food is one of the most effective ways to discourage cockroaches.

Simple prevention tips include:

• Wipe countertops daily.

• Sweep and vacuum floors regularly.

• Store food in airtight containers.

• Wash dishes promptly.

• Empty garbage frequently.

• Clean behind appliances.

• Keep pantry shelves free of spills.

Combined with moisture control and routine treatment, these steps can significantly reduce cockroach activity.

Treat Active Infestations

Removing food sources helps discourage cockroaches, but it won't eliminate an existing infestation on its own.

If you've already seen cockroaches in your home, treat the areas where they hide and travel with a quality roach killer according to the product directions. Combining sanitation with targeted treatment provides the best opportunity for long-term control.
