If you’ve spotted cockroaches in your commercial kitchen, act fast. Roaches in food prep areas can lead to health violations, bad reviews and even shutdowns. The good news is—they can be removed and kept out for good.
In this guide, you’ll learn how to eliminate cockroaches from your kitchen using professional methods, sanitation routines and expert pest control solutions.
How to Get Rid of Cockroaches in a Commercial Kitchen
To eliminate cockroaches in a commercial kitchen, you must clean thoroughly, remove food and water sources, seal entry points and apply professional-grade baits or treatments.
Here’s a step-by-step breakdown that works:
1. Deep Clean the Entire Kitchen
Cockroaches thrive on food debris, grease and moisture. Your first step is to clean from top to bottom.
- Scrub grease traps, exhaust hoods and walls
- Clean behind and beneath appliances like ovens and refrigerators
- Empty all bins daily and sanitize the trash area
- Fix water leaks and wipe standing water under sinks
Even tiny crumbs or drips can feed a roach colony, so precision matters here.
2. Remove All Food Sources
Store all food in sealed containers. Never leave ingredients or prepared meals uncovered—even for a few minutes.
Other key actions:
- Keep dry goods in airtight bins
- Label and rotate food stock to prevent spoilage
- Wipe down food prep surfaces regularly throughout the day
A spotless kitchen is your best defense against pests.
3. Seal Entry Points
Roaches enter kitchens through cracks, pipes and wall gaps. Seal every possible entryway.
Use caulk or steel wool to block:
- Gaps around plumbing and electrical lines
- Cracks in walls, floors or storage areas
- Vents and entry points near garbage zones
Also install door sweeps and window screens where needed.
4. Set Professional-Grade Gel Baits
Gel bait is highly effective for commercial kitchens. Roaches eat the bait and take it back to the nest, killing others through contact or droppings.
Apply gel bait in:
- Cracks and crevices under sinks
- Behind fridges and ovens
- Along baseboards and shelving units
Don’t clean baited areas with strong chemicals or spray insecticides nearby. This can repel roaches from the bait.
5. Install Monitors and Sticky Traps
Use glue traps to track infestation levels and locations. Place them in high-risk areas like corners, under equipment and along baseboards.
Check traps daily and document results to adjust your treatment plan.
6. Use Insect Growth Regulators (IGRs)
IGRs disrupt the life cycle of cockroaches, stopping them from reproducing. Combine them with bait systems for long-term control.
IGRs are ideal for commercial spaces because they help suppress future infestations without constant re-treatment.

Signs of a Cockroach Infestation in a Commercial Kitchen
Early detection makes a big difference. Here are common signs of roaches in food prep areas:
- Droppings: Small, black specs near sinks, drawers and cupboards
- Egg casings (oothecae): Brown or tan capsules hidden in corners
- Musty odor: A foul, oily smell from a growing population
- Live sightings: Especially at night near drains or under appliances
If you notice any of these, take immediate action. Roaches breed fast and spread even faster.
Why Roaches Are Dangerous in a Commercial Kitchen
Cockroaches pose serious health risks in kitchens. They carry bacteria that cause:
- Salmonella
- E. coli
- Gastroenteritis
- Food poisoning
They also leave behind allergens that can trigger asthma attacks, especially in enclosed workspaces.
Even worse, one customer complaint or a poor health inspection could damage your reputation and cost you revenue.
How to Prevent Cockroaches from Returning
After removing them, you need a plan to keep them out for good. Prevention is ongoing and includes:
| Prevention Task | Frequency |
|---|---|
| Deep clean all kitchen zones | Weekly |
| Check for leaks and fix plumbing | Daily |
| Seal new cracks or gaps | Monthly |
| Rotate stock and inspect food items | Each delivery |
| Schedule pest control inspections | Every 1 to 3 months |
Stick to this checklist and you’ll reduce pest risk dramatically.
