Every single one of my tubs (except the hanging basket - though I expect an assault by the little beggars soon) has ants, black ants, red ants, they're everywhere 
Can I get rid of them? Move them on somehow? Do I actually need to do anything? It could just be my gardening that's blighting the pots!
We have ant powder for if they come indoors, but with 3 smallish children and a cat it seems a little drastic to sprinkle it over the garden.
I have some beautiful veronicas out the front which should be gorgeous this time of year yet they're muted at best and I suspect it's because of the sheer volume of ants.
When we took over the house the garden was completely overgrown to a good 4ft and we had anthills the size of small mountain ranges, 8 years on I thought it was more under control but this year is particularly bad.
Any suggestions?
