Description
How Advion Fire Ant Bait works and why it’s beneficial
Advion Fire Ant Bait relies on the active ingredient indoxacarb, present at 0.45g/kg. It works by blocking sodium channels in the ant’s nervous system, and utilises timing to its advantage. Indoxacarb is deliberately slow-acting enough that foraging workers don’t die before returning to the nest, but instead, carry bait granules back for the colony to convert solids into liquid nutrients. Indoxacarb doesn’t break down during the process, but in fact, becomes more potent as it is spread through the queen, larvae, and workers through food sharing. The result is colony-wide mortality.
This is the fundamental difference between Advion and contact insecticides. While a surface spray kills visible ants, the queen will simply produce more workers to replace them. Advion Fire Ant Bait eliminates the source. It also works faster than Insect Growth Regulator (IGR) baits, which take weeks to months and typically 3 to 4 retreatments to be completely effective. Advion can achieve colony eradication in as little as 72 hours with one application, and after the second application 12 to 16 weeks later, offers year-long control.
Applying Advion Fire Ant Bait
- General application rates for Advion Fire Ant Bait are 1.7kg/ha (17g/100m2) for broadcast application, or 15g/mound for individual mound treatment.
- It’s recommended to apply when ants are actively foraging, soil temperatures are above 20°C, and air temperatures are between 24°C and 32°C.
- Morning applications tend to be most effective.
- Do not apply if the area is currently wet with dew, irrigation, or rainfall. Rain within 2 to 3 hours after application may reduce effectiveness and require a repeat application within 7 days.
- Always use fresh baits for best results, as ants are attracted to Advion’s oil content, which degrades once opened.
- Do not apply more than 4 times per year, and always observe 12 to 16-week intervals between applications.
Frequently asked questions
How quickly does Advion Fire Ant Bait work?
Once Advion Fire Ant Bait has been applied, foraging worker activity will drop within 12 to 48 hours. Total colony control, including the queen and brood, typically occurs within 72 hours to 14 days, depending on colony size and density. Two applications 12 to 16 weeks apart can provide year-long control.
Can Advion be used as a red imported fire ant treatment?Â
Yes, Advion Fire Ant Bait can be used to control red imported fire ants — a major pest threatening parts of Queensland and New South Wales.Â
Do I apply the bait on top of the mound?
If applying directly to ant mounds rather than administering via broadcast application, distribute 15g of bait evenly around the mound within 1 metre of where ants enter and forage. Disturbing the mound by applying it on top will cause ants to relocate and reduce bait uptake.Â
Is Advion safe to use on lawns and around buildings?
Yes, Advion Fire Ant Bait is registered for use around buildings, gardens, grazing areas, lawns, and public areas (including commercial and industrial sites). To ensure safety, do not allow livestock or domestic animals to consume the bait directly.
