If you’re smelling something foul or hearing scratching in the walls but can’t figure out where it’s coming from, there’s a good chance your home has a hidden sewer breach. Rats don’t need much to get in, just a small crack in the foundation or an open pipe underground. That’s why we use a method called smoke testing to help pinpoint exactly where the breach is happening.

A smoke test is one of the most accurate ways to identify hidden entry points that rats and other pests use to sneak inside. It works without breaking up walls or digging up floors, making it a favorite tool among top pest control professionals in South Florida.

We use odorless, non-toxic smoke that’s safe for humans and pets. Still, if anyone in the home has asthma or sensitive lungs, we recommend stepping out during the test as a simple safety precaution.

What to Know Before Your Smoke Test

Smoke test for rats in South Florida: for Commercial Buildings and HOAs

If you manage a commercial building or HOA in Palm Beach Gardens, Greenacres, Jupiter Farms, Stuart, or Fort Pierce, make sure to notify your fire alarm monitoring company or sprinkler inspector before the test. This helps avoid unnecessary emergency calls when the smoke triggers indoor sensors.

Why a Smoke Test Can Help You Stop Rats for Good

When rats show up inside, it’s usually not a coincidence. Something underground is breached. Rats often follow sewer lines, using them like highways to enter homes and businesses. A smoke test finds the source, fast.
If a break is detected, you’ll need a licensed plumber or contractor to make the repair — we don’t perform physical pipe work, but we give you the exact location so you don’t waste time or money guessing.
In a place like South Florida where rats, roaches, and sewer flies are common, finding the breach early is key to protecting your home. Don’t wait until the damage gets worse.
