The boric acid usually has to be mixed with something they would want to eat,Most ants are finicky (sometimes it seems they split the kitchen resources so sweet ants can nest in one end, grease ants in the other and mingle freely.) Anyway, it is always worth a bit of observation before spreading poisons to make sure you know your intended audience. We use bottle caps with favorite foods to ID which will be effective then add boric acid to the appropriate one. Samples are: grease, sugar, honey (honey and and sugar ants not the same), meat. Takes very small/short application (and allows dialog for understanding first.) Though one large nest out West we wound up using a dead bird as bait so your big nest may be larger scale for application.
not just straight. Ghost ants are picky eaters (or so I read) and for the
most part they seemed to avoid anything that was tainted. Smart little guys I
guess.
