How Termite Bait Stations Work: Trelona vs. Traditional Liquid Treatments
When it's time to treat a termite problem, most homeowners run into two very different options: a bait system like Trelona, or a traditional liquid treatment applied to the soil around the foundation. Both are effective at what they're designed to do, but they work in completely different ways, and understanding that difference helps explain why we lean on bait systems as our primary approach.
Quick answer: Trelona bait stations use termites' own foraging and feeding behavior to carry a slow-acting substance back to the colony, eliminating it at the source over several weeks to months. Traditional liquid treatments create a chemical barrier in the soil that kills termites faster near the structure, but doesn't necessarily reach the colony itself.

How Trelona Bait Stations Work
Trelona stations are installed in the ground around the perimeter of your home, spaced at set intervals so foraging termite workers are likely to find them as they search for food. Each station starts with an attractant, and once termites are actively feeding, it's replaced with the actual bait. The termites carry that bait back to the colony and share it with their nestmates, including the immature workers and reproductives that never visit the station directly.
How Novaluron Disrupts the Colony
The active ingredient in Trelona is novaluron, a chitin synthesis inhibitor that interferes with a termite's ability to molt. Because termites can't survive without periodically molting, colony members that feed on the bait, or share it with others, gradually die off over the following weeks to months. According to the Alabama Cooperative Extension System, baiting systems are environmentally friendly with extremely low toxicity to humans and pets compared to other treatment types, and they can be installed without drilling or trenching around the home.
How Liquid Treatments Work
Traditional liquid treatments take a different approach entirely. A licensed technician digs a trench around the perimeter of the home and applies a liquid termiticide to the soil, creating a treated zone termites have to cross to reach the structure. Depending on the product, this either repels termites away from the treated area or, with non-repellent formulas, allows them to travel through undetected before it takes effect.
The tradeoff, according to the Alabama Cooperative Extension System, is that liquid treatments generally require more disruption to install and can be more difficult to apply completely around structures with additions, slabs, or complex foundations. They also don't rely on the colony carrying anything back to the nest, so their impact is concentrated at the barrier itself rather than at the source of the infestation.
Key Differences, Side by Side
| Factor | Trelona Bait System | Liquid Treatment |
|---|---|---|
| Installation | In-ground stations placed around the perimeter, no trenching | Trenched or drilled application around the foundation |
| How it works | Termites carry bait back to the colony through natural feeding behavior | Creates a treated soil zone termites must cross |
| Speed | Slower, typically weeks to a few months for colony elimination | Faster knockdown near the treated area |
| Ongoing role | Requires regular monitoring and station maintenance | Generally a one-time application, reapplied as needed |
| Disruption to property | Minimal, no digging or drilling near the home | Requires trenching or drilling around the structure |
Why Envirogreen Uses Trelona
We use the Trelona system as our primary termite treatment because it targets the source of the problem, not just the perimeter of the home. Colony elimination addresses the actual population causing damage, rather than only keeping termites from crossing a treated line, and it does so without the drilling or trenching a liquid application requires.
Built for Long-Term Protection, Not Just a Quick Fix
Because bait stations stay in the ground and get checked on an ongoing basis, they double as an early-warning system for renewed termite activity long after the initial treatment. That ongoing monitoring is part of the value, not an afterthought, and it fits naturally with Envirogreen's no-contract approach: if a station shows activity again, we're already positioned to address it.
What to Expect During Treatment
After a free in-person inspection, we'll walk your property to identify the best station placement based on your home's layout and any existing termite activity. Stations are checked on a regular schedule after installation, and bait is replaced once feeding is confirmed. Because the process relies on termites finding and sharing the bait naturally, full colony elimination takes patience, but it's built to last well beyond the initial treatment window.
When to Call a Professional
If you've already spotted termite swarmers, mud tubes, or damaged wood, or you simply want a proactive inspection before signs appear, a licensed professional can evaluate which treatment approach fits your property. The right system depends on your home's construction and how the termites are already behaving, which is exactly what a proper inspection is for.
