‘Tis the season for the inevitable onset of growing fly populations on farms. Flies are not only annoying to both people and animals, but they can pose a health threat by spreading diseases and infections, and ultimately reduce milk production. Based on research, high populations of stable flies can reduce milk production by 15-30% (Central Life Sciences, 2021).

This is a good area to place pheromone traps. Think fence lines, short walls, and shelves in barns. Finally, flies rest up high. So placing sticky traps or strips above stalls and in rafters out of animal reach is a good way to target them at rest.
