How Do Glue Boards Help Identify Sewer-Based Pest Activity?
If you have ever battled drain flies or American cockroaches, you understand how challenging these pests can be. You complete the inspection, perform the appropriate treatments, address sanitation concerns, and monitor the areas where activity has been reported. The problem appears to improve—then the pests return between service visits.
When standard treatment methods are not producing lasting control, it may be time to look beyond the occupied space and investigate the plumbing system.
Glue Boards Provide More Than a Pest Count
Monitoring boards and fly-light glue boards are valuable tools on almost any pest-control account. They help identify where pests are active, measure population levels, reveal patterns, and show whether a treatment program is working.
However, a monitoring board placed inside a kitchen, restroom, utility room, or commercial facility can only confirm that the pest is present in that area. It does not necessarily identify where the infestation originates.
That distinction becomes critical when drain flies or American cockroaches continue to reappear after standard treatments have been completed.
Recurring Activity May Point to the Plumbing
Drain flies not only breed in organic material inside drains, but they also thrive deep in plumbing systems. Damaged pipes, broken drain lines, and other areas of a plumbing system can provide a direct route into your customers’ homes or business. In most cases unseen, the crack, hole, or break in the pipe is most often concealed. American cockroaches can travel through sewer lines and enter a structure through damaged plumbing, failed seals, dry traps, open connections, or other hidden breaches.
Standard pest-control treatments are typically performed in the accessible areas of a structure. If the source of the infestation is inside the plumbing, those treatments may reduce the pests that emerge without reaching the population where it originates.
This can create a frustrating cycle: activity drops after service, pests continue moving in from the plumbing, and the infestation returns before the next visit.
Monitor Pests Directly Inside the Plumbing System
The Sewer Assassin™ Monitoring Glue Board is designed for use with the Sewer Assassin Plumbing Monitor and Control Station. Its compact 4-inch-by-2-inch design allows it to be placed directly inside either a 3-inch or 4-inch plumbing cleanout.
Instead of only monitoring the room where pests are being observed, the board allows the pest professional to monitor the plumbing system itself.
If the same drain flies or American cockroaches being found inside the structure are captured in the cleanout, the technician now has valuable evidence that the plumbing is contributing to the problem. That evidence can help move the inspection beyond assumptions and toward a targeted solution.
Why Is This Proof Important?
Confirming pest activity in the plumbing helps determine the next step.
When the target pest is captured inside the cleanout, it may be time to convert the Sewer Assassin station from monitoring to treatment and treat the pest directly within the plumbing—where the recurring activity may be originating and where standard treatments cannot reach.
Depending on the site conditions and the products permitted by the label, the station can provide a controlled access point for an appropriate plumbing treatment. Continued monitoring can then help measure the results.
If pests continue to appear, or if the evidence suggests they are escaping from the plumbing into the structure, a professional plumbing fog test may be needed to locate a hidden breach.
The process is simple:
- Monitor directly inside the plumbing cleanout.
- Compare the evidence.
- Treat the directly in the plumbing using the Sewer Assassin clean out station system using products where label allows.
- Use plumbing fog testing when a hidden opening or damaged line is suspected.
One Board, Multiple Glue Monitoring Applications For Pests
Although it was designed to work inside the Sewer Assassin station, the monitoring board is not limited to plumbing applications.
A small adhesive strip allows it to be secured to virtually any suitable surface. Its compact footprint makes it useful in tight, concealed, and hard-to-monitor locations where a larger board may not fit or may be easily moved.
It can be placed on horizontal or vertical surfaces near suspected travel paths, behind or beneath equipment, inside cabinets, near plumbing fixtures, or in other protected monitoring locations. This versatility makes it useful for routine pest monitoring as well as sewer-based investigations.
Stop Treating the Symptom and Find the Source
Recurring drain-fly and American-cockroach activity is not always the result of a failed treatment. Sometimes the treatment never reaches the source.
By placing a monitoring board directly inside the plumbing, pest professionals can gather the evidence needed to determine whether sewer-based pests are entering from a system that is normally out of sight and outside the reach of traditional service methods.
The Sewer Assassin Monitoring Glue Board helps you detect the activity, prove where it is occurring, and make a more informed decision about treatment or plumbing smoke testing.
Stop guessing. Start monitoring the plumbing—and close the final gap in your pest-control program.
FAQs About Glue Boards for Sewer-Based Pest Monitoring
How do glue boards help identify sewer-based pest activity?
Glue boards placed inside a plumbing cleanout can capture pests active within the plumbing system. Comparing these captures with pests found inside the structure helps pest professionals determine whether the plumbing may be contributing to recurring activity.
What pests can the Sewer Assassin™ Monitoring Glue Board help monitor?
The board can help monitor drain flies and American cockroaches inside plumbing cleanouts. Captures provide evidence of activity that can guide further inspection, treatment decisions, and continued monitoring.
Where can the Sewer Assassin™ Monitoring Glue Board be installed?
The compact 4-inch-by-2-inch board is designed for use with the Sewer Assassin Plumbing Monitor and Control Station in 3-inch or 4-inch cleanouts. It can also be secured to suitable surfaces in protected locations, including behind equipment, inside cabinets, and near plumbing fixtures.
Does capturing pests inside a cleanout prove they are entering the building through the plumbing?
A capture confirms pest activity at the monitoring location, but it does not establish the exact entry point into the building. Matching captures with indoor activity provides useful evidence, while further inspection or professional plumbing smoke testing may help locate a hidden opening.
What should pest professionals do after finding pest activity in a plumbing cleanout?
Compare the captures with indoor findings and assess the site conditions. Treatment through the Sewer Assassin station should use only products whose labels permit the intended application. Continue monitoring, and consider professional plumbing smoke testing if a damaged line or hidden breach is suspected.
