How to get rid of cockroaches in commercial refrigerators

"We keep finding roaches near our walk-in cooler. Can cockroaches live in refrigerator units, and how do we get rid of them?"

Cockroaches are drawn to refrigeration units because of the warmth, moisture, and food residue around them, not the cold air inside. The motor, compressor, and insulation panels on the back or underside of a unit generate heat, and condensation from the coils adds moisture. Combined with crumbs or spilled product nearby, this creates an ideal environment for roaches to settle in, even if they can’t survive in the refrigerator’s cold compartment.

How to get rid of cockroaches behind and under the refrigerator

Getting roaches out of these tight, equipment-heavy spaces takes a targeted approach:

• Pull the unit out (where safe) to inspect behind and underneath it for droppings, egg cases, or grease buildup.
• Clean grease and food debris from the compressor housing, drip trays, and floor beneath the unit.
• Seal gaps around door seals, drain lines, and utility penetrations.
• Use professional-grade baits and monitoring placed away from food-contact surfaces.

Because refrigeration units sit in food-handling areas, DIY sprays carry a real risk of contaminating stored product or equipment. Our technicians are trained to treat sensitive cockroach infestations in commercial kitchens, cold storage, and grocery operations, using methods that target hiding spots while minimizing disruption.

For facilities operating under strict food safety audits, our food processing pest control programs can also include refrigeration inspection points in your regular service schedule.
