JustiFLY® Feedthrough is a feed-through insect growth regulator
formulated to help control horn flies, face flies, stable flies, and
house flies in cattle operations. Designed for use in feedlot cattle,
pasture cattle, calves, and lactating or non-lactating cattle, this fly
control solution works by breaking the fly life cycle in manure after
passing through the animal’s digestive system. The easy-to-use add-pack
mixes directly into free-choice minerals, helping reduce handling stress
while providing season-long fly control support.
