Cockroaches eat everything edible and poop in homes and workplaces all across the globe. They’re drawn to food sources they can find too.
Although roaches can go long without eating food, they can spend most of their time either searching for food or eating food, fruits, clothes, and more.
So, what do cockroaches eat?
American cockroaches will eat things like:
- Dead or wounded cockroach.
- Small insects.

What Do CockRoaches Eat in the House?
Roaches are omnivorous insects, happily eating both animal and plant matter.
They’re also dedicated scavengers and aren’t picky eaters. They’d happily feed on just about anything you can consume – and a whole lot more. If it comes from humans, plants, or animals, chances are that roaches will consume it, including food we don’t eat and plant products we consume.
- Cockroaches Eat Human Food anywhere they find it
Cockroaches not only like human food but also prefer certain foods we eat over others.
Naturally, they love greasy foods (such as French fried and things covered in bacon grease and butter), meat products, sweets, and starches (like rice, cereal and breads). They have a strong desire for beer so much that it makes a very nice bait in a homemade roach trap.
However, the secret to stopping cockroach invasion is knowing and denying them easy foods.
- Food on Your Kitchen Surfaces
The kitchen is one place where water and food is everywhere and roaches know this! They love feeding off kitchen surfaces.
Countertop crumbs make a great midnight snack and roaches will go after any processed or fresh food items you leave out.
Some stray vegetables or pieces of pasta in the sink will attract these bugs, and provide loads of meals for them to feed on.
Unsealed leftovers serves as a treasure box for roaches, as are dirty dishes,
- Food in Your Pantry
Sugar, cereal, chops, and other pantry items are like a steak dinner to a bunch of roaches. They’ll chew through cardboard, paper, or even thin plastic containers to get to edible contents inside.
As soon as you spot roaches poops, or any other sign of evidence of bugs inside your food, know that it is contaminated. These bugs come from all kinds of nasty places and carry loads of harmful bacteria to your home.
They can and will live in places the thoughts of will make you cringe.
- Food Crumbs on Your Floor
You cannot handle and control these pests if you cannot get down to their level – that would mean focusing on the floor.
Roaches spend a big amount of time actively crawling around your floor and searching for their next meal. Even flying cockroaches often stick to their feet when they’re out in search of their daily meal.
Your carpet stores food morsels and a roach know how to find them out.
Note: Your house carpet doesn’t have to be dirty to trap loads of crumbs for a cockroach. With its keen sense of smell, a roach can and will locate every crumb that lays there.
- Your Pet’s Food
To be honest, most quality pet food come close to human food (at least that is the way roaches see it).
Since most pet parents will leave a bowl of cat or dog food out overnight, roaches will take advantage of this and will feed themselves till they can take no more.
Each time you leave your pet’s food out in the open, you’re creating a buffet for pests and are calling for more than you can bargain for.
Even if your pet licks off everything, residue and crumbs are still enough to fill a roach’s belly.
- Your Restaurants or Store building
Where there is food – you will find these bugs. Grocery stores and restaurants are places that have food, all the time.
A roach infestation in a market or restaurant can be harmful to the employers, customers and business reputation overall.
Sadly, commercial spaces make and deliver so much food on a frequent basis that it may become hard to keep everything spotless.
That’s why grocery stores and restaurants are at higher risk of facing cockroach problems. If you’re a business owner, it’s best to call in a professional pest control company to inspect and treat your property on particular dates to keep roaches out and bring customers in.
