Sewer Assassin: The Ultimate Sewer Rat Control System for Pest Control Professionals
Rats thriving in sewer systems are one of the most difficult challenges pest control companies face. Beneath every city, restaurant, and multi-unit building lies a hidden network of tunnels that provide ideal conditions for Norway & Roof rats — warmth, food runoff, and constant moisture. These conditions make plumbing a perfect environment for breeding and migration.
Unfortunately, traditional rodent control methods—such as traps, tracking powders, bait stations, and even game cameras—are not effective below ground. That’s why infestations often persist even after extensive abatement and exclusion programs..
Enter the Sewer Assassin, an innovative, patented system designed to let pest professionals detect & eliminate rats directly inside plumbing lines. Built for the toughest underground environments, it provides a safe, durable, and compliant way to target rodents at their source.
In this guide, you’ll learn how the Sewer Assassin works, why it’s trusted by PMPs nationwide, and how to integrate it into your Integrated Pest Management (IPM) service portfolio for long-term, below-ground control.
Why Rats Inside Sewer Systems Are the Hidden Challenge Pest Control Experts Must Solve
City sewer networks are a perfect storm for rodent survival. Norway rats (Rattus norvegicus) thrive in dark, damp areas rich in food waste and organic debris. These underground environments offer everything they need to nest, breed, and move undetected between buildings.
Rats frequently use drain and sewer lines as subterranean highways, traveling from restaurants to dumpsters, and between structures that share plumbing connections. Their activity can go unnoticed until damage, contamination, or visible sightings occur above ground.
The challenge for pest professionals is that traditional baits and traps fail. In many cases PMP’s don’t look to the possibility of intrusion through plumbing until all other methods have been exhausted, and numerous call backs have occurred.
Introducing the Sewer Assassin™ System — The Next Generation Bait Station for Sewer-Based Rodent & Pest Control
The Sewer Assassin is a professional-grade sewer bait station designed specifically for pest control technicians working in commercial, municipal, and dense urban environments.
This patented device replaces a standard cleanout cap and fits directly into 3-inch and 4-inch cleanouts commonly found in most infrastructure. Inside the sealed unit, bait or monitoring blocks are suspended above the waterline, or placed horizontal in wall above drains, keeping them dry, secure, and accessible only to rodents that would be inside plumbing systems.
By positioning bait exactly where rats are traveling, the Sewer Assassin allows PMPs to treat & prove infestations at the true source — inside the plumbing system — without exposing bait to the exterior environment.
How the Sewer Assassin™ Works — A Revolutionary Bait Station for Sewer-Based Rodent & Pest Control
The Sewer Assassin™ transforms any 3” or 4” cleanout into a fully functional bait and treatment station, giving pest professionals a reliable way to control rodents directly within the sewer system. Designed for easy installation, long-term performance, and compliance, it delivers consistent results where infestations start — below the surface.
Here’s how it works:
- Replace the existing cleanout cap with the Sewer Assassin bit and treatment station.
- Attach EPA/label -approved bait blocks . to the device turning any 3” or 4” clean out into a working bait station.
- Make tamper resistant by simply tightening cap to ensure compliance, safety, & discretion,
Once installed, the system begins delivering consistent rodent control in plumbing systems, while adding new consistent revenue to your pest control operations.
The design prevents bait washout and limits access to non-target species — making it the only rodent control method attacking sewer and plumbing infrastructure.
Why Pest Control Companies Trust Sewer Assassin
results that traditional surface treatments can’t:
- Built tough for commercial and municipal systems.
- Reduces callbacks by treating the source of the infestation.
- Keeps treatment out of sight, maintaining clean, compliant service for food and public-facing environments.
- Improves IPM standards, technician safety, and regulatory compliance.
By integrating the Sewer Assassin into their programs, PMPs can finally control rodent populations before they ever exploit plumbing routes and appear inside structure.
FogTrace™: Detecting Rodent and Sewer-Based Pest Activity with Precision
For maximum precision, the FogTrace smoke testing system pairs perfectly with the Sewer Assassin.
- If Sewer Assassin confirms rodents are present in plumbing, the FogTrace identifies where the cracks, breaches, and rodent pathways are, within the plumbing system.
- Technicians can then pinpoint the most active cleanouts for Sewer Assassin placement.
- By performing your own plumbing smoke tests with the FogTrace, you can prove the fault isn’t in your treatment methods, but in the failing plumbing infrastructure of your customers home or business.
Together, these tools offer a fully visual and measurable way to close the plumbing gap, confirm treatment success, and report it to clients with confidence.
Proven Results: How Sewer Assassin Performs in Real-World Pest Control Environments
The Sewer Assassin system is proving its effectiveness across a wide range of accounts:
- Restaurants and food facilities plagued by recurring rodent, roach, and drain fly issues.
- Municipal sewer departments addressing public health risks.
- Multi-unit residential buildings sharing plumbing and drain systems.
Across these environments, PMPs report fewer reinfestations, improved inspection outcomes, and increased client satisfaction thanks to below-ground control.
How to Add Sewer Assassin to Your Pest Control Program
Integrating Sewer Assassin into your IPM workflow is simple and scalable:
- Inspect plumbing lines with FogTrace to identify activity.
- Locate high-activity cleanouts in kitchens, basements, or utility areas.
- Install Sewer Assassin units at all new jobs to first prove the pests presence, then control it!
- Load or apply appropriate bait and document treatment details.
- Maintain and service units during scheduled service visits to ensure ongoing protection, while generating new revenue in the process.
This systematic approach allows pest professionals to transform plumbing systems from invasion points & breeding grounds into control zones.

FAQs About the Sewer Assassin™ System
1. How does the Sewer Assassin™ work inside plumbing systems?
The Sewer Assassin replaces a standard 3” or 4” cleanout cap, transforming it into a professional-grade bait and treatment station. EPA/label-approved bait blocks are secured inside the device, positioned directly within active sewer or drain lines where rodents travel. This allows pest control technicians to target infestations at their true source—below ground—while preventing bait washout and exposure to non-target animals.
2. Why is the Sewer Assassin more effective than traditional rodent control methods?
Unlike surface traps or outdoor bait stations, the Sewer Assassin operates within the plumbing system itself—where Norway and roof rats breed and migrate. Traditional tools fail to reach these environments, leading to repeat infestations and costly callbacks. The Sewer Assassin’s underground design ensures long-term, discreet, and compliant control that directly addresses the root cause of sewer-based infestations.
3. Can the Sewer Assassin be integrated into existing IPM programs?
Absolutely. The Sewer Assassin is built to enhance Integrated Pest Management (IPM) strategies by adding a new below-ground control layer. PMPs can use FogTrace™ smoke testing to locate active lines, install Sewer Assassin units at strategic cleanouts, and monitor or rebait during regular service visits. This method improves documentation, technician safety, and customer satisfaction. It’s the only system that targets sewer-based pests when plumbing is part of the issue.
4. Where can pest control professionals purchase the Sewer Assassin system?
The Sewer Assassin™ is available through leading pest management distributors, including Veseris, Chemtech Supply, and Turf & Pest. You can also visit SewerAssassin.com to request a quote, view installation videos, or schedule a demo.
