Plug the hole with white mint-flavored toothpaste! They hate the mint and the abrasives are bad for their exoskeleton. I imagine that the detergents in it don't do their little tummies any good at all. Anyway, they won't chew through it. If you know where the nest is, make some tobacco "tea" and pour a goodly quantity down it. (Best use for tobacco that I know of :thumbsup: ) It sends them into convulsions. Ants also will import aphids to your plants- they love the sweet secretions that aphids make and raise them like we raise cows for milk. - Granny:hippy:
