The Sewer Assassin™ Pest Strip Holder: The First and Only System Designed to Control Sewer-Based Pests at Their Source
For decades, pest management professionals (PMPs) have battled a frustrating and costly reality: American cockroaches and drain flies repeatedly infest homes and commercial properties even after thorough sanitation, drain treatments, enzyme cleanings, and interior applications. Technicians return, customers stay frustrated, and the cycle continues.
At the core of the issue is an often-ignored truth—the pests aren’t coming from the structure. They’re coming through it. The real adults and breeding sources are hidden deep inside sewer lines, drain stacks, and branch lines, far beyond the reach of any traditional control method. As long as those populations remain untouched, reinfestations are guaranteed.
Until now, PMPs had no purpose-built, reliable solution to place long-term control inside the plumbing system itself.
The Sewer Assassin™Nuvan Pest Strip Holder changes that. It is the first and only patented device engineered to sit inside a plumbing cleanout and deliver continuous, targeted suppression of sewer-based pests using Nuvan® ProStrips. For the first time, PMPs can take control directly at the source—where traditional tools have always failed.
Why Traditional Treatments Fail: The Adults Are Still in the Plumbing
Surface treatments can only reach so far. PMPs may treat every visible site—floor drains, sink drains, splash zones, wall voids, expansion joints, and baseboards. And still, within days, customers report pests returning.
Here’s why:The adult populations never left.
American roaches and drain flies thrive inside:
- Sewer and plumbing mains
- Branch lines
- Vertical stacks
- Under-slab lines
- Damaged or poorly vented sections of plumbing
These hidden areas are wet, organic-rich, protected, and completely insulated from conventional sprays, dusts, baits, foams, or gels. Even the best surface-focused IPM program cannot impact the deep internal harborage zones where the pests breed.
If there is a structural or plumbing defect, pests continue living happily inside the system—and as soon as treatments dissipate, they reinvade like nothing ever happened.
The Sewer Assassin™ Pest Strip Holder breaks that cycle.
It’s the first device that lets PMPs put a controlled-release vapor inside the plumbing, moving into the same inaccessible areas pests use as breeding and travel routes.
How the Sewer Assassin™ Works With Nuvan® ProStrips
Nuvan® ProStrips utilize DDVP (dichlorvos), a proven vapor insecticide ideal for enclosed environments. When paired with the Sewer Assassin holder, it becomes a powerful tool for sewer-based pest suppression.
The controlled-release vapor:
- Moves effortlessly through enclosed plumbing networks
- Penetrates deep into pipes, stacks, and voids
- Delivers continuous knockdown for weeks
- Reaches adult roaches, drain flies, and other sewer pests where they actually live
Placed inside a cleanout through the Sewer Assassin holder, the strip releases a consistent, targeted vapor that fills the interior plumbing system. Instead of chasing pests at the surface, PMPs now control them inside their primary habitat. The definition of proactive not reactive treatments.
The Result True Long-Term Control:
Fewer callbacks
Significantly reduced reinfestations
Consistent suppression of sewer-origin roaches and drain flies
A proactive treatment strategy that finally addresses the underlying cause—not just the symptoms
This is the first time PMPs can implement real source control inside the sewer system, giving them long-term, predictable results instead of temporary relief.
Easy Installation: Designed for On-Site Speed and Efficiency
One of the biggest advantages of the Sewer Assassin system is how simple it is to deploy.
Most properties—homes, restaurants, warehouses, retail stores—have an exterior, in-ground main cleanout. Once this cleanout is located, installation is straightforward:
- Remove the existing cleanout cap.
- Attach the pest strip holder to the Sewer Assassin station.
- Insert the Nuvan ProStrip into the holder.
- Drop the holder into the cleanout and secure the Sewer Assassin cap
- Document placement and service frequency.
This process takes minutes and immediately targets the plumbing network where infestations originate. No specialty training or additional equipment is required.
Solving Previously Unsolvable Problems
For decades, PMPs have faced service accounts where:
- Sanitation is perfect
- Drains are clean
- Treatments are done correctly
- Yet sewer roaches or drain flies still return
In these scenarios, PMPs were often forced to say, “There must be something going on with your plumbing—you may need a plumber.”
But plumbers rarely test for pests. PMPs lacked the ability to place control inside plumbing, leaving a major gap in IPM programs.
The Sewer Assassin Pest Strip Holder finally fills that gap.
It targets the root of the problem—adult infestations hidden in the pipes—and gives PMPs a solution for cases previously labeled “unfixable.”
New Revenue, More Value, and Stronger Customer Retention
Since this is the only system of its kind, it naturally creates new service opportunities:
Recurring Revenue
The controlled-release strips last weeks, creating a predictable replacement schedule and new recurring service line for customers.
Premium Service Offering
Solving chronic sewer-based infestations positions your company as a high-level problem-solver—not just a general pest provider.
Customer Retention
When you solve issues that others can’t, customers don’t leave. You become the company that finally gave them relief.
Less Callbacks
Targeting the source significantly reduces reinfestation cycles, saving your team time and resources.
A New Standard in Sewer Pest IPM
The industry has long understood the role plumbing plays in pest movement and harboring—but until now, we didn’t have a tool built specifically for controlling pests inside that environment.
The Sewer Assassin™ Pest Strip Holder is that missing piece.
- It gives PMPs unprecedented access to the internal plumbing system.
- It solves long-term problems that were previously unsolvable.
- It generates new revenue while providing better protection for customers.
- And it delivers true source-based control using a proven vapor technology.
For the first time, PMPs can confidently say:
“We can treat the infestation at its source—inside the plumbing.”
This is the future of sewer-based pest control, and it starts with the Sewer Assassin™ system.

FAQs About the Sewer Assassin™ Pest Strip Holder: The First System to Treat Sewer-Based Pests at Their Source
1. Why do sewer roaches and drain flies keep returning even after proper treatments?
Most reinfestations occur because the adult populations are still alive inside the plumbing system, far beyond the reach of conventional surface treatments, foams, gels, or drain enzymes. Floor drains, sink drains, and wall voids may be treated correctly, yet the real source remains untouched in sewer lines, branch lines, and vertical stacks. Until the internal plumbing is treated, pests simply migrate back into the structure. The Sewer Assassin™ Pest Strip Holder targets these hidden zones directly.
2. How does the Sewer Assassin™ Pest Strip Holder work with Nuvan® ProStrips?
The holder secures a 16-gram Nuvan® ProStrip inside a plumbing cleanout, allowing controlled-release DDVP vapor to move through enclosed pipe systems. This vapor spreads effortlessly through stacks, mains, and branch lines—reaching the breeding adults where they actually live. The result is continuous source-level knockdown for weeks, something no traditional IPM method can accomplish on its own.
3. Is installing the Sewer Assassin™ system complicated or time-consuming?
Not at all. Most properties already have an accessible exterior cleanout. Installation takes only minutes:
- Remove the cleanout cap.
- Insert the ProStrip into the holder.
- Attach the holder to the Sewer Assassin station.
- Drop the assembly into the cleanout and secure the cap.
- Document service intervals.
No special tools or training are required, making it one of the easiest upgrades to existing IPM programs.
