Afternoon

We have had an increasing problem with ants in our house, not just food areas (although kitchen is actually spared mainly) but upstairs and here and there and (almost) everywhere. I'm not sure if it is the hot weather, last summer was a lot milder, but thought I'd see if we were the only ones with unusual ant activity.
I remember years (decades) ago when we had huge amounts of those little cockroaches for a couple of summers, and I have read somewhere that ants come inside more when its going to rain bigtime..... but the problem with that is no.... Sydney is not in for a deluge any time soon.....
Anyone else have too many ants?
Thanks
