The proportions of boric acid and sugar are rather important.
At least, it seems that way with the ants around here.
Too much borac acid and the ants won't take it. Too little
and it ain't gonna kill the colony.
The Terro liquid ant baits work better than anything else
I have been able to make or buy commerically. My local ants
love that stuff and although it may take a few days, it does
wipe out the nest.
Boric acid injected into cracks and crevices where it won't
get blown or washed away does seem to be quite effective
at deterring the little buggers from creating freeways
through those areas.
Keep in mind that different ants (depending on species and
the availability of other food sources) may be seeking
"sugary" food but they may be after "fatty" food. In the
latter case, something like peanut butter laced with
boric acid may be more effective.

Since the OP didn't ask, I didn't mention it, but I second the Terro
recommendation. I had a friend that was trying to deal with a nasty
carpenter ant infestation and was using those small, useless plastic
white-flower-looking ant baits. The ants totally ignored the things
and the traps had been in place for weeks with no effect.
I recommended the Terro traps and offered to help. The Borg didn't
carry the Terro liquid, but a local hardware store did. One day later
the traps were full of carpenter ants. Two days later there were even
more ants feasting. Third day - no ants at all.
As another person posted, the boric acid is good for spritzing dry
into crevices and along sill plates and such.
Grin, Either way, it's the main method I've used but then I'm trying to keep
the back yard safe for the dog as well. If still working from an organic
aspect, Boric Acid is pretty safe. You could mix some with sugar water and
soak the hills?

For insects the DE needs to be the food grade DE, not that used in
pools systems. The difference: food grade DE is not processed using
heat. It's just the way it was harvested. The jagged edges remain on
the fossil. Pool DE is heated and that rounds the edges off the
fossil. Rub each between you thumb and finger -- feel the difference.
The sharp edges on the fossil is what causes havoc on the critters.
Were those instant grits?

For carpenter ants, I put down liquid ant bait from
www.gardensalive.com in bottle caps, or tupperware lids. they bellied
up to the bar, drank heartily, and didn't come back. This was maybe
five or more years ago. the Orkin guy wanted $175 per treatment, and
Orkin closed, and the place is now a daycare. I'm not sure I'd want to
house kids in a building that used to have pesticides.
