What are Horse Wormers?
Horse wormers (or dewormers) eliminate internal parasites in your horse. They are administered orally in paste, pellet or liquid form. All horse wormers are simple to use, easy to obtain and relatively inexpensive. Until 2005, horse wormers were recommended on regular intervals of 4 to 8 weeks; but since that time experts have come to believe that healthy adult horses do better with quarterly or biannual dewormings. Horses that are exposed to more frequent wormings will build up a resistance, while horses left to minimal exposure will build up a strong immunity to internal parasites over time. If you are in doubt as to when to use a horse wormer, fecal egg count tests are available through your veterinarian. It should be noted that the tests are only 40% to 90% accurate for tapeworms and bots.
