Solutions Invented by Professionals, for Professionals
ATC Thermal was founded by real pest control professionals. Every system we design and every solution we build is backed by decades of hands-on experience and field-tested performance.
ATC Thermal is part of the ATC family—a multi-generational pest control company with more than 30 years of real-world field experience. From our headquarters in Pennsylvania, we’ve helped thousands of customers eliminate infestations safely, effectively, and responsibly.
Along the way, we saw the gaps in traditional heat treatment firsthand—systems that added moisture, required extreme temperatures, increased risk, and delivered inconsistent results. We knew there had to be a smarter way.
So we built one.
ATC Thermal helps pest professionals to eradicate bed bugs for their clients, every single time.
Thermification™ is a patented dry-heat remediation process that combines indirect-fired heat with active de-humidification to fundamentally change how thermal treatments work. By removing moisture from the environment, Thermification™ lowers the effective thermal death point—allowing bed bugs and their eggs to be eliminated at up to 30°F lower temperatures than conventional heat systems, with faster kill times and significantly reduced risk.
Operators. Educators. Innovators.
The ATC Radio Show
Every Saturday evening, Bryan Guderjohn and Ashley Almony host the ATC Radio Show—a live, educational podcast focused on answering the pest control industry’s most common and most complex questions. From pest identification and seasonal behavior to prevention strategies and treatment science, each episode delivers practical guidance grounded in real field experience.
ATC doesn’t just talk about the work—we do it. We actively operate, train, and deploy the same systems we teach, drawing on decades of hands-on pest control and thermal remediation experience to educate both professionals and the public.

Heat, Perfected by Science
When you choose ATC Thermal, you’re not purchasing a generic heat system—you’re partnering with the team that developed, patented, and field-validated a smarter approach to bed bug remediation. Like most professional pest control companies, we began with the standard heat treatment systems available at the time. They worked—but only if you accepted slow ramp-up times, heavy equipment, electrical strain, and constant compromises as “normal.”
Then COVID hit.
Supply chains collapsed. Critical components were discontinued. We exhausted domestic options and even worked directly with overseas manufacturers in an attempt to source replacement parts—only to learn the parts simply were no longer being made. The industry’s core technology had quietly aged out. Instead of moving forward, the industry moved backward. Electric heat systems became the fallback. They were slow, extremely heavy, punishing on electrical infrastructure, and unreliable in real-world conditions. Breakers tripped. Buildings couldn’t handle the load. Generators were constantly down for repair. Treatments took longer, setups became more demanding, and efficiency suffered across the board.
That’s when the question changed from “How do we make this work?” to “Why are we still doing it this way?” The initial push to rethink the equipment came from Bryan, a lifelong pest control operator who recognized that the tools we were using no longer matched the realities of modern treatment work. But recognizing the problem was only the first step.
Ashley took that idea and carried it forward—breaking down the science, testing real-world applications, rebuilding workflows, and ultimately transforming a concept into a fully engineered system. She bridged field experience with physics, operations with safety, and theory with execution. This wasn’t a lab experiment. This wasn’t a manufacturer’s brainstorm. This was built by a family of professional pest control operators, solving problems they faced every day in the field. We didn’t set out to invent something new. We set out to make the job work the way it should. What followed was a complete rethinking of thermal remediation—how heat moves, how moisture changes outcomes, how equipment should support operators instead of fighting them. The result wasn’t an upgrade to existing technology.
It was an entirely new approach.
Invented by professionals.
Built by a family business.
Designed for the real world.
