The article said that they used, "[...]Spinosad, a bacterial insecticide considered harmless to humans and most beneficial insects." Boric acid kills bugs. All of them (as far as I understand). Based on this incomplete data it looks like if Boric acid were used it would have to be baited with something that would not attract friendly bugs. Perhaps a vat of pig's blood laced with Boric acid or something similar would only kill of blood sucking insects. That'd be kind of nice...
