Can rats really come up through a toilet?

Yes. Sewer rats are strong swimmers and can navigate up through a toilet trap if there's an opening anywhere in the line between your home and the city sewer. It's more common than most people realize, especially in neighborhoods with older or deteriorating plumbing.

Is this a pest control problem or a plumbing problem?

Both — but the plumbing comes first. The breach in your sewer line is the source. Bait stations and traps can reduce the population, but new rodents will keep entering through the same opening until it's sealed. We handle the plumbing side and can refer trusted pest control for the removal side.

How do you find the entry point?

A sewer camera inspection comes first — we run a camera through the line looking for cracks, joint separations, or damage. If the camera doesn't reveal a clear breach, we follow up with a smoke test that pressurizes the line with non-toxic smoke to expose hidden openings.

Will I need to excavate my yard?

In most cases, no. Many sewer line repairs are completed using trenchless methods that require no digging. After we assess the line, we'll tell you upfront whether trenchless will work for your situation.

Does this happen more in older homes?

Yes — older homes are at higher risk. Clay and cast iron pipes are more prone to cracking and joint failure over time, creating entry points. That said, we've seen sewer rodent intrusions in newer construction too.

A growing East Valley problem

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.

This isn't a cleanliness issue. It's a plumbing issue and it needs to be addressed at the 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.

Think you have a sewer rodent problem? The sooner the entry point is identified, the less damage they can do.

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.

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.
