Aint that the truth Henry the Sgt Ants the big red bu**ers here well you go past their nest they usually have 1 guarding the entrance just stir them up to see what happens droves just come pouring from the nest the only way to really kill'em is to get them under your heel and spiral on them as stomping just seems to infuriate them even more...............
I used a concoction on them which mirrored Napalm (gelatinous petrol mixture) had to do it in the cooler months in case you set fire to the wheat crop
