The Evolution of Plumbing Smoke Tests: From Smoke Candles to FogTrace
For many years, plumbing smoke tests have been a go-to diagnostic method for spotting cracks, leaks, and breaches in drain and sewer lines. This is especially true in commercial settings where pests like rodents, roaches, and drain flies can sneak in through the plumbing. In the past, these tests relied on smoke candles, which were dependable but have become somewhat outdated. This method has its drawbacks, particularly in today’s fast-paced pest control landscape.
The Era of Smoke Candles
Before modern fog machines took the stage, smoke candles were the go-to solution. These sulfur-based sticks were ignited and placed in the trays of fan-based smoke test machines, releasing thick, heavy smoke into plumbing systems to uncover any leaks or weaknesses in the pipes. For years, smoke candles were the industry standard—affordable, effective, and easy to use. But everything changed when a devastating fire wiped out the main manufacturing plant that produced most of the country’s smoke candles.
This disaster brought supply chains to a grinding halt. Professionals in the field found themselves waiting months for new shipments, and when the candles finally hit the market again, prices had soared, transforming what was once a budget-friendly option into a financial strain. This was especially problematic on job sites where multiple tests were necessary, like in large commercial kitchens, warehouses, or hospitals. The cost of using several candles per site quickly became unmanageable. It was clear: the industry was in desperate need of a better solution.
The Rise of FogTrace: Modern Testing for Modern PMPs
Introducing FogTrace—the groundbreaking smoke testing tool crafted just for pest management pros. This innovative device uses top-notch fog machines to create a thick, visible, and odorless fog that mimics smoke, minus the downsides of sulfur candles.
So, why is FogTrace the smarter choice? With FogTrace, pest control companies can enjoy:
- Instant readiness—no waiting around because of supply chain hiccups.
- Significantly reduced operating costs, especially for sites that need multiple test points.
- Reliable performance, with no open flames, no ash, and absolutely no sulfur smell.
But What About the Smell?
Many seasoned PMPs will share this insight: the smell of smoke can be a surprisingly useful tool. Often, you can catch a whiff of a leak before you even spot it, which is crucial for pinpointing those tricky breaches. The good news? There are plenty of fogging agent companies out there that offer customizable scent options. While the standard fog is scent-free, perfect for homes and indoor spaces—you can enhance it with light, air-freshener-like fragrances that replicate the effect of smoke candles without that lingering sulfur stench.
Here are some popular scent choices:
- Citrus or Fresh Linen (ideal for indoor settings)
- Mint or Menthol (sharp and noticeable in larger areas)
- Buttered Popcorn (for those techs who enjoy a tasty treat)
These scents are temporary, clean, and gentle on the senses, unlike the harsh, lingering smell of burnt sulfur that can cling to carpets, curtains, or ductwork for days.

Smoke Testing for Rodents & Roaches: FogTrace FAQs & Pro Insights
What is a plumbing smoke test, and why is it used for pest control?
A plumbing smoke test pushes visible vapor through drain and sewer lines to reveal cracks, leaks, or breaches where air escapes, indicating structural issues and potential pest pathways.
In commercial and residential settings, this method helps identify entry points for rodents, American roaches, and drain flies so technicians can target exclusion and treatment more effectively.
Why are traditional sulfur smoke candles falling out of favor?
Sulfur-based smoke candles were once the affordable, easy-to-use standard, producing thick smoke via fan-based machines to expose plumbing weaknesses.
A major plant fire disrupted supply chains, causing long delays and price spikes that made multi-point testing costly, while drawbacks like open flames, ash, and lingering sulfur odor further reduced their practicality.
What is FogTrace, and how does it improve smoke testing?
FogTrace uses a professional fog machine to generate a thick, visible, odorless fog that mimics smoke without sulfur, flames, or ash, improving safety and cleanliness on site.
It offers instant readiness without supply-chain bottlenecks and significantly lowers operating costs for jobs requiring multiple test points, especially in large facilities like commercial kitchens, warehouses, and hospitals.
Can fog-based tests still use scent to help locate leaks?
Yes—while standard FogTrace fog is scent-free, technicians can choose fogging agents with light fragrances so leaks can be detected by smell as well as sight.
Common options include citrus, fresh linen, mint, menthol, and buttered popcorn, and these scents dissipate quickly without the harsh, persistent residue associated with burnt sulfur in carpets, curtains, or ductwork.
