4 Signs That You Have A Cockroach Infestation

There’s no doubt about it– cockroaches love restaurants. Even clean establishments can experience a cockroach infestation if they don’t have an effective pest control program in place. The scary thing with cockroach infestations is that most owners don’t even know they have a problem until it becomes severe. That’s because cockroaches love to hide in small crevices and cracks during the day, waiting to come out at night to eat. This makes it difficult to spot them, but there are still some ways to identify potential red flags so you can nip any problem in the butt. Whether you’ve noticed a cockroach or are just feeling concerned, here are some key signs that you have a cockroach infestation in your restaurant. If you notice any of these, hire a pest control professional right away to inspect and apply the necessary treatment.

A Strong Musky Odor

Mold isn’t the only problem that gives off a strong odour. A cockroach infestation can also emit a musky, oily-like odour. Even if there are no apparent signs of cockroaches, a persistent smell stemming from cracks and crevices or under the sink can indicate an infestation. 

Egg Casings

A cockroach casing carries up to 50 eggs. Once the eggs have hatched, a small, long and brown oval casing will be left behind. If you find more than one lying around, it’s a sign that you could have a serious problem with these pests.


Another red flag to keep an eye out for is the presence of small, coffee-like grounds laying around cracks and crevices. These tiny grounds also resemble black pepper, but they’re actually cockroach feces and often indicate that there’s a nest nearby.

Body Parts

Although cockroaches typically die on their back, which makes it easy to spot them, cockroaches are also cannibals in nature. They will eat the body of another roach that has died, leaving bits of it on the floor. If you spot random bug parts, especially bits of shell, it’s a sign that you have a cockroach infestation.

Expert Advice

Why Cockroaches Are A Concern?

Once a cockroach moves into your restaurant, they immediately start to multiply. One German cockroach can produce up to 50 eggs at a time and create up to 8 egg casings over its lifespan. In just one year, they can produce close to 500 offspring that further reproduces. And like all pests, they search for hiding spots with close access to food and water. Cockroaches not only eat the food, but they also pass on bacteria and viruses like salmonella and are known to heighten allergies and asthma symptoms. 

What Can You Do To Treat and Prevent Them?

Applying a spray or setting traps won’t treat a cockroach infestation. To eliminate cockroaches for good, you need a professional pest control treatment that will destroy the nest and all of the egg casings. Since restaurants are so vulnerable to infestations, it’s important to have a routine pest control plan in place that involves regular building inspections and touch up treatments when needed.
