The Valley Has a Sewer Rodent Problem and It's Getting Worse
Phoenix is seeing a serious rise in sewer-based rodent intrusions. As the area grows rapidly, aging infrastructure and expanding neighborhoods create ideal conditions for rats to move from city sewer systems directly into residential plumbing and then into your home.
What that means for your home:
Chewed Pipes & Structural Damage
Rats gnaw through PVC, ABS, and cast iron to create and widen access points throughout your plumbing.
Contamination & Health Risks
They carry serious health risks for your household including Leptospirosis, Hantavirus, and Salmonella.
A Pest Problem that Won't Stop
Without sealing the entry point in the sewer line, new rodents will continue entering no matter how many traps are set.
Foul Odors & Hidden Damage
Decomposing material inside walls and compromised pipe seals create persistent odors with no obvious surface source.

How Sewer Rodents Enter Phoenix homes
- 01
City sewer system
Rats live and breed inside municipal sewer lines, the same network that connects to every home. 02
Cracked or deteriorated lateral line
A breach in your home's sewer lateral, from aging pipe, root intrusion, or soil shift, creates an entry point.03
Entry into the home's plumbing
Rats navigate the breach and into your internal drain system including the toilet trap.04
Inside your home
Without a plumbing repair, they establish nesting, chew insulation and wiring, and contaminate the structure.
The Yellowstone approach
We Find the Entry Point and Seal It for Good
Sewer rodent problems are a plumbing problem first. Pest control companies can set bait and traps, but if the entry point in your sewer line isn't identified and addressed, new rodents will continue to enter.
We focus on the plumbing side of the problem by locating the breach, repairing it, and coordinating with pest control professionals for the removal side.

We don't just send a pest control referral. We inspect your sewer line, find where they're getting in, and fix it so the problem doesn't come back.
01
Acoustic Leak Detection
Sensitive listening equipment picks up the sound of water escaping under pressure, even through concrete slabs, soil, and wall cavities. Pinpoints the leak without opening anything up.
02
Sewer Smoke Testing
When a camera inspection isn't enough, a smoke test reveals hidden breaches by pressurizing the line with non-toxic smoke. If there's an opening in your plumbing, the smoke will find it. This is one of the most reliable ways to confirm whether your sewer system has a gap that's allowing rodent entry.
03
Pipe Repair or Lining
Once the breach is located, we repair it. Depending on the condition of the pipe and the extent of the damage, we'll recommend the right method:
Trenchless Pipe Lining (CIPP)
A resin liner inserted and cured in place, a new pipe wall inside the old one, no excavation required.
Targeted Spot Repair
For isolated cracks or joint failures that don't require full line replacement.
Pipe Replacement
For sections too far deteriorated to reline, installed properly and to current code.
04
Cleanout Cap Assessment
We evaluate your existing cleanout caps and fittings to ensure no open or improperly sealed access points are present. An unsecured cleanout cap is one of the most commonly overlooked rodent entry points.
05
Pest Control Coordination
We coordinate with pest control professionals for trapping and monitoring when needed. We handle the plumbing. They handle the population. Together, you get a complete solution and not just a temporary fix.
Schedule a Sewer Camera Inspection
We'll find the entry point or rule it out completely.
Know the warning signs
Signs You May Have a Sewer Rodent Issue
Some of these are obvious. Some are easy to miss or misattribute. If you're seeing more than one, it's worth a call.
A Rat In or Near Your Toilet
Not a fluke. If a rat has surfaced in your toilet, your sewer lateral has a breach large enough for active entry. This needs immediate inspection.
Scratching Sounds Inside Walls or Ceilings
Especially at night. Movement in wall cavities is a strong indicator of an established rodent presence that entered through the plumbing.
Foul, Unexplained Odors from Drains or Walls
Distinct from normal sewer smell, a persistent organic odor inside walls or from drain openings can indicate rodent activity in the line.
Pest Infestations that Keep Coming Back
If you've had pest control out multiple times and the problem keeps recurring, the entry point is almost certainly in your plumbing and not just in your walls.
Slow or Sluggish Drains Throughout the House
Rodent activity and debris buildup in a cracked lateral can partially restrict flow and show up as slow drains at multiple fixtures simultaneously.
Chewed Wiring, Insulation, or Plumbing Material
Discovered during repairs or renovation and a clear sign of an active rodent presence. Trace where they came in, not just where they've been.
Visible Rodent Droppings Near Plumbing Access Points
Around cleanouts, under sinks, or near the base of toilets — droppings near plumbing indicate the access point is in the drain system, not just above ground.
If you've had pest control out multiple times and the problem keeps coming back, the entry point is likely in your plumbing. Don't wait, these problems don't go away on their own.
