Tango is available, not at the Ag station, but at CPS (Leilani st in Hilo)...but it is wayyyyy expensive - over $600 for 2.5 gals....
I have used Amdro granular formulations ("Ant Block Perimeter" & Fire Ant Bait") , (have had luck with the barrier treatment around the house & on trails, limited luck with bait stations, luck mainly right on trails to fruit trees. We can usually get a good reduction for about a month with a full treatment, but the neighboring hordes will re-establish into the dead ants mounds, and we have to start all over again. This summer we started treating 2 neighboring yards & got another week or 2 out of a treatment...so this is probably best done on a large plot area.... but....
We are now trying Amdros newest & bestest (maybe) "Firestrike Yard Treatment" which again is a corn cob granular base with the old formulation (hydramethylnon) PLUS the S-Methoprene larvae inhibitor of Tango.... it has the same rain problems as the other two... we spread it around our orchard area and perimeter a week ago... ants are still using the trails, but less...
One problem with Tango & this new Amdro product is that they are not fast kill products, it supposed to take MONTHS to see the population decrease, as s-methoprene works on the larval development, not on the adult ants....
So we will see if this newest & best is any better....
