With teeth clenched, no flies enter. Silence and restraint protect a person from trouble — keeping one's mouth shut is a form of practical wisdom.
The Lombard preference for reticence over verbal extravagance finds one of its most vivid expressions in this proverb, which frames silence as a literal hygiene measure. In the agricultural world of the Po Valley, where flies were a summer constant in stables, markets, and kitchens, the image was viscerally relatable. More metaphorically, the saying warned against the dangers of indiscreet speech in a city where the political winds changed constantly under Spanish, Austrian, French, and eventually Italian rule — under each new master, the wrong word in the wrong ear could cost a man his livelihood or his liberty. Carlo Porta's dialect poems show Milanese characters practicing exactly this discretion, saying much with their eyes and little with their mouths. The proverb complements the Lombard archetype of the silent worker who lets deeds speak louder than words.
The agricultural imagery of flies in the Po Valley summer makes this proverb vividly Lombard; its message of discretion was particularly relevant under successive foreign administrations when political speech was dangerous.
