A bottle of Tango is about $60 and IIRC makes enough for at least three acres worth of ant bait. It's for making up the gel bait for spraying into trees, which are otherwise very hard to get LFA out of. If you're targeting ants on the ground, Siesta is a relatively low-toxicity alternative to Amdro - same type of granular bait but different active ingredient. It works just as well in my experience, though both have trouble when it's wet. Bifenthrin is so poisonous you don't really want to use it except as a barrier treatment around your house after you've gotten rid of the ants inside.
