You are so right about the Amdro having a short period of effectiveness. You definitely do not want to apply it late in the day when the ants are getting ready to retire because it won't be effective during their next active cycle.
There is a fire ant bait called Advion that contains the same active ingredient as Provaunt but the HAL said the results were inconsistent, so they ranked it low. Their highest ranked bait granule is Siesta and I can say from experience is not only the best at attracting and killing them, it also holds up well in moisture. Apparently it is effective even if it gets wet, though I've never put it to that test.
"Siesta Insecticide Fire Ant Bait is the only sodium blocker Insecticide that does not require metabolism for bioactivation. It acts on the nervous system, where it blocks the voltage dependent sodium neuron channel. Ants will soon stop feeding, start becomming immobile and then eventually die.
Chemical Family: Semicarbazone
Mode of Action: Metaflumizone is part of a new Insecticide Resistance Action Committee (IRAC) Mode of Action Chemical Group, 22B
Behavior in Ants: Acts through ant ingestion with limited contact activity. Feeding cessation begins quickly - within 15 minutes to 12 hours of ant recruitment of the bait. Insects will die within 72 hours."
