Sentinel Rodent Control System – Below Ground Protection
Always on Guard. Always Working.
Advanced, Non-Toxic Sewer Rat Control with Smart Monitoring
Rats in sewer systems pose a serious and often hidden threat to homes, food facilities, and sensitive production environments. The Sentinel Sewer Rat Trap from A1 Exterminators delivers a strategic, humane, and poison-free solution that stops rodents before they surface—while giving you real-time monitoring and control.
With its mechanical kill system, CO₂-powered piston, and smart reporting, the Sentinel is built to perform in even the harshest sewer environments, ensuring year-round protection.
Reliable, Flower-Friendly, and Cost-Effective Surface Installation
- Fail-Safe Design – Mechanical kill function even during power failure
- Flow-Friendly – Does not obstruct wastewater flow
- Surface Installation – Easy setup, operation, and maintenance from ground level
- Cost-Effective – Competitive pricing with low ongoing maintenance costs
The trap is securely mounted inside a sewer drain from ground level, adapting to various pipe sizes.
Rats attempting to pass are guided into a sealed killing chamber.
A piston delivers an instant, humane kill.
The rodent is flushed away with the normal wastewater flow.
Even during downtime or malfunction, the trap’s fiberglass damper acts as a permanent rat barrier.
This method avoids the resistance problems seen with chemical baits and eliminates the risk of secondary poisoning to wildlife.
Built-In Rat Barrier (“Rat Rafter”)
The Sentinel functions not only as a trap but also as a physical barrier within the sewer system—preventing rodent movement into protected areas at all times. Rats cannot lift or bypass the built-in locking system, ensuring continuous protection.
