Why Most Ant Treatments Fail — And What the World's Leading Researcher Taught Me
By Owen Stobart, ACES Pest Control Auckland
In October 2020, while most of the world was locked down, I found myself in a virtual NPMA Pest World meeting alongside pest controllers from all 50 states of America. It was the only time in the NPMA’s 87-year history that PestWorld had ever been held online — originally scheduled for Nashville, moved to virtual because of COVID. The presenter was Dr Robert Puckett from Texas A&M University — the world’s leading researcher in ant super colony management, brought in by the National Pest Management Association to train the entire US pest control industry.
Dr Puckett is known for treating SUPER colonies of ants. Think nests as big as your house, but in the ground.
I was expecting to learn something new. What I got was confirmation that what ACES had been doing in Auckland was right — and a crystal clear explanation of why so many other treatments fail.
The Problem With Most Ant Treatments
If you’ve had ants treated before and they came back, this is probably why.
For ant control most pest controllers reach for fast-acting products. You see a lot of dead ants. It looks like it’s working. But here’s what’s actually happening — those dead ants are all workers. Foragers. The expendable ones. The nest, the queens, and the next generation of ants? Completely untouched.
It gets worse. Ants are remarkably adaptive. Dr Puckett showed video footage of exactly this scenario — fast-acting products creating a perimeter of dead ants, while the colony carries on regardless just centimetres away. Within a short time, surviving ants simply learn to walk over their dead nestmates. The product that killed the first wave stops affecting the ones that follow. The colony has essentially trained itself around fast acting treatments.
You’ve paid for a pest controller. You’ve got a pile of dead ants and a thriving nest.
The Science of What Actually Works
Dr Puckett spent his session rating every major active ingredient available to pest controllers on a scale of one to ten for super colony management. His number one? Termidor — whose active ingredient is fipronil.
Number two was Imidacloprid. Number three indoxacarb.
The ranking wasn’t based on how quickly each product kills ants. It was based on the opposite — how slowly.
Here’s why that matters.
When an ant contacts Termidor, it doesn’t die immediately. It stays alive and mobile for long enough to return to the nest, groom its nestmates, feed the larvae, and interact with the queens. At every point of contact, the treatment transfers. The colony’s own behaviour — the constant grooming, feeding, and movement that makes super colonies so successful — becomes the delivery mechanism that destroys it.
The longer the delay, the deeper the penetration. The deeper the penetration, the more queens are reached. Reach the queens and you end the colony.
Fast-acting products never get there. The ant dies at the perimeter and takes the treatment with it.
Why Super Colonies Need a Different Approach
Dr Puckett deals with super colonies in Texas so vast that nests can be the size of a house. Where standard treatment might cover one metre out from the nest, he gets special permission to go further. Same product, same principle — scaled to the size of the problem.
Argentine ant super colonies in Auckland share a remarkably similar genome across the entire city — which is why they cooperate rather than compete, merging many nests into one super nest around your home or business. The science Dr Puckett applies in Texas applies directly here. Treat beyond what you can see, use a product with the the longest delay of action available (fipronil), and let the colony’s own biology do the work.
What This Means For Your Home
If you’ve had ants treated and they’ve come back, ask your pest controller one question: what active ingredient did you use, and how does it reach the queen (s)?
If they can’t answer that question, the ants will be back.
At ACES, every treatment is built around the science Dr Puckett confirmed — Termador, applied on the exterior (no interior spray), getting colony’s biology to work for us, taking the termador inside the nest/colony. Not because it’s the cheapest option. Because it’s what the world’s leading researcher independently ranked as number one.
