Why Do I Still Have Rat Problems?

Youâve heard the scratching. Youâve seen the droppings. Maybe youâve even hired a pest control company alreadyâyet the rats keep coming back. Itâs a frustrating, unsettling problem, and youâre not alone. But the question remains: why do you still have rats?
The truth is, rat infestations are often more complicated than people realize. Let’s break it down.
You Might Be Creating Your Own Problem
We get itâlife gets busy. But rats are opportunists. Any accessible food, water, or shelter can attract them. That forgotten dog bowl outside, the overflowing garbage can, or even a cluttered garage can be an open invitation.
Sanitation is your first line of defense. If food and water sources are readily available, no amount of trapping will solve the issue. Rats will simply return, again and again.
Not All Pest Control Is Created Equal
Hereâs something many people donât realize: pest control professionals often specializeâjust like doctors. You wouldnât visit a podiatrist for heart surgery. So why hire a generalist PMP (pest management professional) to solve a complex rodent issue?
Rat control isnât just about setting traps. It takes deep knowledge, investigative skill, and a sharp eye for exclusionâthe art of identifying and sealing off every single entry point rats might be using.
If your PMP isnât trained or experienced in exclusions, they may miss critical vulnerabilities, leaving your home open to reinfestation.
The Hidden Culprit: Your Plumbing System
One of the most overlooked entry points for rats? Your plumbing system.
Most peopleâand even many PMPsâdonât consider that rats can come up through the sewer. Yes, you read that right. Rats are agile swimmers, capable of navigating through flooded pipes, sewer lines, and even the U-bend of your toilet to enter your home.
Old or damaged cast iron pipes, degraded seals, and vent stacks without proper screening can create invisible on-ramps from the sewer into your walls, attics, and basements.
Historically, when PMPs suspected plumbing entry points, theyâd say, âCall a plumber.â That often meant more cost, more confusion, and more delaysâwith no guarantees of success.

Enter the Sewer Assassin
Today, top-tier PMPs no longer have to guessâor outsource.
With the Sewer Assassin, pest professionals can now inspect, monitor, and control rat activity coming from the sewer system themselves. No more waiting on plumbers. No more speculation. This tool is a game-changer for rat control in homes and businesses alike.
Using smoke testing, physical barriers, and bait station monitoring designed specifically for sewer lines, PMPs can confirm if rats are using your pipes as a secret highwayâand do something about it.
Final Thoughts
Still have rats? Ask yourself:
- Have all food and water sources been eliminated?
- Have all structural entry points been professionally sealed?
- Has your plumbing system been inspected as a possible access point?
- Is your pest control provider truly specialized in ratsâand capable of exclusions?
If the answer is no to any of the above, it may be time to bring in someone who knows how to think like a ratâand block every possible path.
Rats are persistent. But with the right tools, knowledge, and commitment to exclusionâincluding plumbingâthe problem can be solved, and the Sewer Assassin is helping lead that charge. Itâs the worlds first and best rodent bait station to combat rats coming into homes and business, originating from the sewer system.
