We seem to have developed a little ant problem!
It's strange because they are coming up through the overflow hole in the bathroom sink! They aren't in the kitchen so it's not food that they're looking for - I think maybe they are after water but I can't get rid of that!
Does anyone have any miracle ways of getting rid of the little buggers? I have got Mortein any baits in there and have also put down Antrid. They seem to love theant rid but it's as though they come back each day just to eat it - I have been battling with them for a week now and there seem to be more and more each day. They are driving me nuts!! HELP.

We tried almost everything to get rid of the ants coming into our house. Ant baits did nothing, they marched straight past them, we only used Antrid out the front because we have dogs in the backyard. Finally we got some Mortein Professional outdoor surface spray and that finally worked! It took a while (because they had actually set up a nest INSIDE our house in the wall cavity!) we haven't seen any from about a week after we sprayed around everything (windows, doors, vents, eaves).
