A Conversation with Jonathan Sargent, M.S. (Entomology), Owner of Sargent Pest Control
One of the most common questions homeowners ask is simple:
“What are the most common pest problems you see homeowners dealing with in our area, and what do you wish more people understood about why those pests show up in the first place?”
To answer that, we asked Jonathan Sargent, owner of Sargent Pest Control and a Clemson University–trained entomologist.
“South Carolina’s Climate Is a Big Factor”
According to Jonathan, the biggest driver of pest problems in the Upstate is our climate.
“Because South Carolina stays relatively warm year-round, we see a large variety of pests trying to get inside homes and businesses.”
Unlike colder northern states where winter slows insect activity dramatically, Greenville’s mild winters allow many pests to remain active for much longer stretches of the year.
That means pest pressure doesn’t fully “shut down” in the winter months. Instead, it shifts.
The Most Common Pests in Greenville
Jonathan says a handful of pests keep his team especially busy:
Large roaches
Ants (especially persistent colonies around foundations)
Spiders
Rodents
Each of these pests is highly adaptable. And each one is typically responding to the same three basic needs: food, water, and shelter.
When those needs are met near or inside a structure, pest activity increases.
Why Do These Pests Show Up in the First Place?
One of the most important things Jonathan wishes more homeowners understood is this:
“One of the things we try to do as a company is to look for any conducive conditions around your home or business that makes it more attractive to these pests.”
In entomology and integrated pest management (IPM), the term conducive conditions refers to environmental factors that make a property more inviting to insects or rodents.
These can include:
Excess moisture around foundations
Wood-to-soil contact
Cracks and entry points around doors or windows
Overgrown landscaping touching the home
Food sources (including pet food or unsecured trash)
Gaps in crawlspaces or attic vents
Removing or reducing these factors doesn’t guarantee you’ll never see another pest—but it dramatically reduces the likelihood of ongoing problems.
Prevention vs. Reaction
Jonathan explains that effective pest control isn’t just about spraying and leaving.
“If conducive conditions can be removed or mitigated, you may still see pests occasionally, but it should be less.”
That’s the difference between short-term elimination and long-term control.
Because Jonathan holds a Master’s Degree in Entomology from Clemson University, Sargent Pest Control approaches pest management from a science-based perspective. Instead of simply reacting to visible pests, the focus is on understanding:
Why they’re there
What’s supporting their activity
How to interrupt their life cycle
That’s how you move from constant pest frustration to consistent protection.
The Takeaway for Greenville Homeowners
If you live in Greenville, Greer, Simpsonville, or the surrounding Upstate areas, pest activity isn’t unusual. Our climate makes it inevitable to some degree.
But recurring infestations usually point to something more than “just bad luck.”
They point to conditions that can be addressed.
And that’s where expert-level identification and prevention make all the difference.
