They build a network of underground homes, spreading out far and wide.  A commercial product called AMDRO does work on them, but completely inappropriate for using in food growing areas. 

Bifen is also said to work.  Since it is a product made from the chrysanthemum plant, and so is a less expensive product I use called PyGanic, i use the latter, but seem to keep finding new hills all the time to treat.  PyGanic used to be considered an organic compound, but I am not sure it still qualifies as organic.

By the way, you should know that JWA does help a little bit in deterring the ants if applied often.  They don't seem to like the taste.

So, I read on the internet that SUGAR could be used and that it would be taken to the nest and dry out the exoskeleton of the queen.  Finally, to my question: does this make sense to you in your knowledge of insects and chemistry?

(I haven't found diatomaceous earth to be very effective.)  Since sugar is organic, it would be a cheap and easy fix, if it is feasible that it might work.
Please give your opinion.
