I'm the kind of person who has a lot of time on my hands (school summer holidays
) so my personal approach would be to follow them back to their nest and use small explosives to remove the problem
of course baking powder and vinegar are just as fun and less noisy (though both will ruin surrounding area, if done effectively
)
Are the ants doing any damage? I see ants carry away dead plant waste, though now thinking, those scissor ants cut leaves to ribbons.
