When we moved into the house the garden needed some TLC. We sorted it out and in the process discovered lots and lots of ants. I mean lots. The nests were under a path of paving slabs which we took up and disposed of. We like to garden without pesticides but on this occasion we bought the nastiest, most chemically horrible stuff we could and blitzed the place.
Result - no more ants (although next door complained some time later that his garden was mysteriously full of ants ).
That was 4 years ago but now the little blighters are back with a vengeance. They are in my compost bin, coating my rhubarb and spinach and are also all over my climbing rose which is in a planter at the other end of the garden. They're everywhere.
Help! I can't really cover the whole garden in ant powder. Can I? Should I? What do I do?
