Case Study - German Cockroach Control – Town Centre Fast Food Outlet

Key Takeaway

A busy town centre fast food outlet faced a significant German cockroach infestation. A structured Integrated Pest Management (IPM) approach was implemented, including inspection, chemical treatments, gel baiting, monitoring, and staff guidance. Follow-ups and specialist investigation addressed persistent activity and potential migration from nearby properties. Cockroach sightings dropped to near zero, cleaning standards improved, and the infestation was brought under control. Ongoing preventive measures—such as monitoring, proofing, and routine maintenance—ensure continued protection and compliance.

Introduction

German cockroaches (Blattella germanica) present one of the highest risks to food businesses due to their rapid breeding cycle, resilience, and ability to exploit even minor hygiene or structural vulnerabilities. This case study details the successful control of a significant infestation within a busy town centre fast food outlet in Herefordshire, achieved through a structured, evidence-led Integrated Pest Management (IPM) programme.

The client required a solution that was fast, effective, legally compliant, and operationally discreet, with zero compromise to food safety standards.

The Challenge

A busy fast food outlet in a town centre was experiencing a significant German cockroach infestation, with sightings reported across kitchen and preparation areas. Multiple life stages were present, indicating an established breeding population. Due to the food-handling environment, the client required a fast, effective, and compliant solution with minimal disruption to operations.

Our Approach

We implemented a structured Integrated Pest Management (IPM) programme, combining targeted chemical treatments, gel baiting, intensive monitoring, and client collaboration.

Phase 1 – Assessment & Initial Control

• Full site inspection confirmed German cockroach activity across multiple areas

• Immediate treatment using a high-strength residual insecticide and gel bait to achieve rapid knockdown and long-term control

Phase 2 – Intensive Treatment & Monitoring

• Multiple follow-up visits to target harbourage areas including wall and floor junctions, roof voids, and behind equipment

• Strategic placement of labelled bait stations and monitoring traps

• Activity levels closely tracked using lures and sticky traps

Phase 3 – Re-Treatment & Refinement

• Re-treatment carried out where necessary to eliminate persistent activity

• Cleaning practices adjusted to ensure residual insecticide effectiveness

• Ongoing guidance provided to site staff to support treatment success

Phase 4 – Specialist Investigation

• Accompanied inspection with a field biologist

• Identified only minimal residual activity above the false ceiling

• Root cause investigation expanded to include potential migration from adjacent residential properties

The Results

• Dramatic reduction in cockroach activity within weeks

• Staff reported sightings reduced to near zero

• Cleaning standards improved and fully aligned with pest prevention best practice

• Infestation brought under control with only isolated findings during final monitoring

Ongoing Prevention

To prevent reinfestation, we recommended:

• Inspection of electrical equipment and hidden voids

• Monitoring of adjacent residential properties

• Sealing of structural gaps and proofing works

• Routine drain maintenance

• Continued use of pheromone-based monitoring traps

The Outcome

Through a proactive, professional, and methodical approach, we successfully reduced a high-risk cockroach infestation to controlled, minimal levels.

Continued monitoring and preventative measures ensure the client remains protected, compliant, and confident in their pest management programme.
