Eggs are laid singularly on surface of dung, not dung inside buildings. Minimum development is 7 days, the larvae leave the dung and pupate in surrounding soil.
Adults emerge from puparium in the morning.
Adults feed on facial secretions-tears, nasal mucus, saliva, blood from wounds. Fly numbers can be reduced by sanitaion, thus reducing breeding places. Stacking manure in heaps causes it to ferment, high internal temperatures will kill fly larvae and eggs. Topical applications of insecticides- permethrin, Dimilin sprayed onto manure heaps.
