How to Incorporate a Sewer Assassin & FogTrace as standard operating procedure (SOP) into your treatment programs.

Modern pest control is no longer about how well you treat—it’s about how quickly and accurately you identify the true source of the problem. Sewer-based infestations are one of the most overlooked contributors to chronic rodent, American cockroach, and drain fly issues. By incorporating a clear SOP using the Sewer Assassin system and FogTrace plumbing smoke testing, PCOs can close one of the biggest gaps in conventional pest control programs.

This article outlines how to seamlessly integrate these tools into your existing treatment plans to deliver stronger results, higher customer confidence, and long-term recurring revenue.

Step 1: Start With Rats – Proving Activity Inside the Plumbing

When dealing with rodent activity—especially in accounts with repeated interior sightings or failed exclusion attempts—the first SOP step should be proving or disproving sewer involvement.

The Sewer Assassin cleanout bait station allows you to turn any 3” or 4” sewer cleanout into a working sewer-based bait station. By starting with a non-toxic bait, you immediately gain diagnostic clarity without jumping straight to control. By installing a Sewer Assassin on the day you set traps and monitors, you can find out on your first trip back if the issue is plumbing related.

Why this matters:

If bait disappears, you now have clear, documented evidence of rodent activity inside the plumbing.
This proof immediately changes the conversation with the customer—from speculation to facts.
It strongly indicates that rodents may be entering the structure through plumbing breaches, not just exterior walls or doors.

Instead of guessing, you now know the source—and you can build the treatment plan around that knowledge.

Rodents aren’t the only pests using plumbing as a hidden highway. When American cockroaches and drain flies persist despite repeated treatments, it’s often a sign that the real problem isn’t being addressed—what’s happening inside the plumbing system itself.

Step 2: When Roaches and Drain Flies Don’t Respond—Look to Plumbing

American cockroaches and drain flies are classic examples of pests that thrive inside sewer systems. Too often, PCOs exhaust:

Residual sprays
Baits and dusts
Sanitation recommendations
Trapping
Repeated callbacks

When all conventional treatments fail, the reality is simple: the infestation is likely originating in the plumbing system itself.

This is where the Sewer Assassin changes the game.

The Sewer Assassin system gives PCOs the ability to:

Detect sewer-based pest activity
Prove the source to the customer
Treat pests directly inside the plumbing where they live and breed

Whether it’s rodents, American roaches, or drain flies, Sewer Assassin allows you to control pests at the source instead of chasing symptoms inside the structure.

Identifying the source is only half the solution. For real consistency across accounts, sewer-based detection and treatment must be easy to deploy, easy to document, and easy to repeat—making SOP integration the logical next step.

Step 3: How Easy Is It to Incorporate Into an SOP?

One of the biggest advantages of the Sewer Assassin system is how easily it fits into existing treatment programs.

The SOP is simple:

If you are treating for any of the three common sewer-based pests—rats, American cockroaches, or drain flies—install or use a Sewer Assassin station on day one.
Monitor activity just as you would any other bait station. Or monitor the effectiveness of your regular treatments.

Clear outcomes tell the story:

If bait disappears → activity is confirmed in the plumbing.
If the pest problem clears up → you have successfully treated inside the sewer system, not just the building.

This turns sewer treatment into a repeatable, standardized process, not a specialty service that feels complicated or risky.

Step 4: Confirm the Source With FogTrace Plumbing Smoke Testing

Once sewer involvement is proven, the next SOP step is identifying how pests are entering the structure.

This is where FogTrace plumbing smoke testing becomes essential.

FogTrace allows PCOs to:

Introduce high-density, scent-free fog into the plumbing system
Visually pinpoint cracked pipes, failed seals, broken vents, and hidden breaches
Identify exact locations where sewer-based pests are escaping into walls, floors, and living spaces

Instead of telling customers “there may be a plumbing issue,” you can now show them exactly where the failure exists.

This elevates your role from pest control provider to problem-solver and trusted advisor.

While bait activity confirms what’s happening inside the plumbing, confirmation of how pests are entering completes the picture. FogTrace plumbing smoke testing allows PCOs to visually trace sewer pathways and document structural breaches with absolute clarity.

The Business Impact: Why This SOP Matters

PCOs who incorporate the Sewer Assassin and FogTrace into their treatment plans gain more than just better control—they gain a competitive advantage.

Key benefits include:

Increased customer confidence through clear proof and documentation
Solving infestations at their true source, not just treating symptoms
Proactive IPM instead of reactive callbacks
Higher customer retention due to long-term results
New, consistent revenue from sewer monitoring and smoke testing services

Most importantly, this SOP allows you to close the final gap in pest control programs—the sewer system.

From Guesswork to Proof: How Sewer-Based Pest Control Delivers Better Results

If you are serious about rodents, American cockroaches, and drain flies—and serious about IPM—then sewer-based pest control can no longer be ignored.

By standardizing an SOP around Sewer Assassin for detection and treatment and FogTrace for confirmation and documentation, PCOs can deliver stronger results, differentiate their services, and build lasting customer relationships.

The future of pest control isn’t more treatments—it’s better answers.

Sewer-Based Pest Control FAQs: SOPs, Detection & Proof for Modern IPM

1. Why should sewer inspections be part of a standard pest control SOP?

Sewer systems are a primary breeding and travel route for rats, American cockroaches, and drain flies. When infestations persist despite traditional treatments, the source is often inside the plumbing—not the structure itself. Adding sewer inspection and monitoring to your SOP allows you to identify root causes faster, reduce callbacks, and deliver long-term solutions instead of repeated treatments.

2. How does the Sewer Assassin fit into existing treatment programs?

Sewer Assassin integrates seamlessly into standard rodent, roach, and drain fly programs. By installing it on day one using non-toxic bait, PCOs can immediately determine whether pests are active inside the sewer system. It functions like any other monitoring station—simple, repeatable, and easy to document—making sewer-based detection a standardized process rather than a specialty add-on.

3. When should PCOs suspect plumbing-related pest activity?

Plumbing involvement should be suspected when:

Rodent issues persist after exclusion and trapping
American cockroaches continue despite baiting and residuals
Drain flies return after repeated sanitation and treatment efforts

If traditional methods fail, the infestation is likely originating in the sewer system. Sewer-based monitoring confirms this quickly and eliminates guesswork.

4. What role does FogTrace play in the SOP?

FogTrace is used after sewer activity is confirmed to identify how pests are entering the structure. By introducing high-density fog into the plumbing system, PCOs can visually locate cracked pipes, failed seals, broken vents, and hidden breaches. This turns assumptions into documented proof that customers can see and understand.

5. How does adding sewer-based SOPs improve customer retention and revenue?

Sewer-based SOPs shift pest control from reactive treatments to proactive problem-solving. PCOs benefit from:

Clear proof and documentation for customers
Fewer callbacks and stronger long-term results
Increased trust and professional differentiation
New recurring revenue from sewer monitoring and smoke testing

Instead of selling more treatments, you’re delivering better answers—and customers stay because the problem is truly solved.
