Methods for reducing flying insects from animal feeds or animal feed supplements involve, in a location accessible to flying insects, providing a livestock animal with an animal feed or a liquid supplement and a palatant or a molasses replacement in an amount effective to reduce flying insects from occupying an area on and around the animal feed or the liquid supplement. The palatant or the hydrolyzed whey within the palatant may account for at least about 2 percent of the animal feed or liquid supplement by weight. The hydrolyzed whey may be hydrolyzed whey, whey permeate or delactosed whey permeate containing melanoidins.
