Fly populations can be a major nuisance for livestock. A common method for dealing with livestock fly control is the application of products containing insecticides. Different kinds of dusters, oilers, and sprays are available for the routine maintenance of these unwanted pests. Lice dusters for cattle and swine provide control of fleas, ticks and lice. Long-lasting livestock pour-on remedies offer relief from horn flies, face flies and biting lice.
