Face fly control approaches

Considerable research with a nematode that destroys female ovaries and a pupal parasite that killed the pupae was conducted in Nebraska, but neither proved effective enough to be employed for control.

The insecticides recommended for control of horn flies will also control face flies. The dusts, sprays, oiler mixes, some feed additives, boluses and ear tags registered for control of horn flies also are registered for face fly control.

The exception is methoprene feed additive and bolus. The pyrethroid insecticide ear tags are registered for face fly control, but should be rotated annually with other insecticides because of horn fly resistance. — WLJ
