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

How It Works Below Ground Rodent Elimination

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.
