I never found it particularly effective. Certainly didn't
eradicate them.


I found it had to be fresh Nippon liquid, even if it had just been in
the shop for a while it seems to loose it's killing power.

Whenever I've used Nippon I always had the impression the ants threw a party!

That's the point. it's a sugar syrup with a poison in it that the
foragers take back to the nest and feed to the other ants. It helps to
remove all other food sources so they are just getting the special stuff.

I think the poison is borax. I've found it a bit hit-and-miss: I
wonder if there's more skill and savvy involved in using it than meets
the eye.
