To quick. Stake the savages out naked over an ant hill and let the hungry little guys go at ‘em.
OH COME ON! You didn’t mention FIRE ANTS! The other kind take too long. You want a body picked clean in 16 hours?!? Contract the job out to fire ants. We can pay them double. It will still be cheaper than that injectible cocktail that we always seem to not have enough of, and the shelf life is running out (an efficient system that we would always have enough and never waste a dose)... so there are efficiencies right there alone, that can be improved upon.
Particularly the fire ants. These are some nasty little fellers.
