I don't normally mind having ants in the garden, but
this year there seem to be 10 times more thn normal!
The garden is swarming with them.

I've tried putting down Nippon ant bait (the liquid
type from sqeezy tubes) but there's no sign yet, after
a week or so, of any fewer ants. A lot of the ants
(there are at least 5 nests) don't seem interested in
the Nippon at all.

Any ideas of other stuff to try..?
