there re no effective natural remedies agains that pain in the u know (i mean those bloody ants which i hate very much). anyway, there is very very very good remedy – baition from bayer. it is a powder, u dissolve it in water and poor into holes where those nasty things live. in evening u do that in the morning they all re dead. i used it under plants too, it doesn’t harm plants. i also have kids and i do not think it is harmful for kids – liquid is absorbed into soil and i don’t think your kids re playing under plants. anyway, i gave that advice before and a man wrote that he couldn’t find bayer in usa. how can that be? yes, this is the same firm which makes medicines. and i wouldn’t advice u to buy those granules which u put near ants’ home and they re supposed to carry it in and die later. that never happened to me. so the same bayer makes raid in granules in a fancy blue bottle. that doesn’t help against ants. anyway, if u don’t find that particular product by bayer u find anything which u dissolve in water and poor it inside, not granules. good luck. u know that those nasty ants spread aphids on plants cos they eat their sweet residue? nasty

You can also make ant bait from diatomaceous earth and peanut butter.
However… ants do not eat plants. They are on your plants because of the aphids that are making honeydew. Ants eat honeydew. Kill the aphids and the ants will go away.
