Well I poured the dregs of a sprayer containing clove oil and water onto a
ant hill in the lawn
about two months ago ( I know, stupid or what?). It got rid of the ants
all right, but it also
killed the grass as well. In fact there is still a brown patch the size of
a dinner plate. I'm
waiting to see how long it takes the grass to grow back. Incidentally, at
the same time a tree
feller spilled petrol on the lawn, which killed the grass as well, but
that has now regenerated so
you cannot see where it was.

So, beware, clove oil is good, but it will kill plants if they are
overdosed.

Rick...

Thanks for the advice Rick. I will use it sparingly.
