The main advantage of boric acid is that it's not significantly toxic to the other darkroom denizen -- the photographer (though you should read the MSDS for it, as it can have some effects -- most notably, it's a laxative). You can also use it as a photographic chemical; it's a nice buffering agent in some formulae.
I'm afraid my Greek isn't up to translating (in fact, almost all the Greek I know is related to food), but you want the acid form of the borate ion. Borax isn't right, that's sodium tetraborate. Boric acid is H3BO3, you might think of it as "hydrogen borate". (darn it, HTML is off and there's not vB code for subscripting)
Extra advantage: boric acid kills ants and fleas as well, and the ants will carry it back to their nests before they die, killing out the whole colony in many cases.
