Expert Review: Verified by The PCC Research Team
Every homeowner has experienced it: You place a bait station on the kitchen counter, watch thousands of ants swarm it, and celebrate when they disappear a few days later. But two weeks later, a new trail of ants marches right back across your floor.
If you are trapped in an endless loop of killing worker ants without ever stopping the colony, the problem isn’t your bait placement—it is the active ingredient inside your bait. This is the exact reason professional exterminators use Advion Ant Gel instead of the Terro Liquid Baits you find at the grocery store.
Wait! Are You Seeing WINGED Ants?
If the “ants” swarming your home have wings, they may actually be a termite swarm looking to establish a new colony in your walls. Do not use ant bait.

The 2026 Verdict: The Speed of the Kill
When it comes to baiting social insects, killing them too quickly is actually a bad thing. You need the worker ants to live long enough to feed the queen.
Advion Ant Gel (Pro Grade)
Uses a highly engineered, delayed-action neurotoxin. It guarantees the worker ant has enough time to carry the lethal bait deep into the nest, ensuring total colony collapse.
Terro Liquid Baits (DIY)
Uses a sugar syrup mixed with Borax. It works well for small, isolated ant problems, but the high borax concentration often kills workers too fast before they can share it with the colony.
Quick Navigation:
1. The Science: Why Terro Often Fails Long-Term
Both products rely on “Trophallaxis”—the process where foraging worker ants consume liquid food, carry it back to the nest in their social stomachs, and regurgitate it to feed the larvae and the queens.
The Flaw in Terro (Borax)
Terro utilizes Sodium Tetraborate Decahydrate (Borax) at a 5.4% concentration. Borax works by disrupting the ant’s digestive system. The problem? 5.4% is a highly lethal concentration. Worker ants often ingest the sweet syrup and die on their journey back to the nest. You see a pile of dead ants next to the bait station and think it worked, but the queen was never fed the poison. She simply breeds more workers to replace the ones you killed.
The Power of Advion (Indoxacarb)
Advion is manufactured by Syngenta using Indoxacarb. This is a highly advanced, non-repellent active ingredient that requires the ant’s own enzymes to convert it into a lethal form. This creates a mandatory delay in mortality. The worker ant can consume a massive amount of gel, safely return to the deepest parts of the colony, and transfer the poison to multiple queens before finally dying 24 to 48 hours later.

3. The California “Super-Colony” Problem
If you live in California, the ants in your kitchen are likely Argentine Ants. This species forms massive “super-colonies” that stretch for miles, containing hundreds of individual queens cooperating together.
Terro’s borax stations simply cannot dent an Argentine super-colony. The only way to stop an invasion of this scale is to combine a high-quality interior bait like Advion with a professional exterior liquid trenching barrier (such as Fipronil/Termidor) to cut off the colony’s supply lines.
4. Frequently Asked Questions
Q: Why are there suddenly MORE ants after I put out Advion?
A: This is supposed to happen! It means the bait is working. Do not kill them or spray them. Let them gorge on the gel so they can carry maximum amounts back to the nest. The trail will vanish in roughly 48 hours as the colony collapses.
Q: Can I use bug spray next to the bait?
A: NEVER. Spraying Raid or any other repellent near Advion or Terro will contaminate the bait. The ants will smell the poison, avoid the bait completely, and your infestation will continue.
Q: Will Advion dry out?
A: Yes, gel baits lose their moisture over time. Place small, pea-sized dots of gel rather than long lines. Check the dots daily and refresh them if they are fully consumed or look hard and crusty.
