Ok so weve lived in the same house for 6 years and NEVER had ants! UNTIL NOW.... we are overrun with them. I have tried spraying them, putting ant baits down, and they just move to the next room for a while (including the bathroom!) and then they come back after a while... I have wiped out all the places they hide, so as not to attract them, but they still seem to come back.

We have had our house sprayed for spiders (outside) and had insulation put in recently, maybe this has forced them inside??

Any ideas would be greatly appreciated!! They are doing my head in!
