Horses get tapeworms from forage mites that have ingested tapeworm eggs. Forage mites live in horse pastures, lawns and vegetation and feed on horse manure. As the horse digests the forage, tapeworms emerge from the infected mites and attach themselves to the intestinal lining of the horse. Once the tapeworms mature, they shed their eggs into the manure of the horse. The cycle begins again when mites in the pasture consume the eggs.
• Tapeworms can infect horses of nearly any age but horses between three and five years and older than 15 years harbor the greatest number of tapeworms.
• Tapeworms can't be directly transmitted from horse to horse.
• Forage mites favor temperate climates.
• Tapeworms are most common in late fall because higher humidity helps the tapeworm eggs move from the grass to the grass mite to your horse.
