stir up a hornets' nest, to

To provoke a quarrel or foment trouble. The analogy appears in the Roman playwright Plautus’s Amphitruo (ca. 200 b.c.), in which Sosia tells Amphitryon not to get in trouble by quarreling with his wife. It is cited by Erasmus in his collection of adages and repeated by Rabelais in Pantagruel. In English it appears from the eighteenth century on and remains current.
