Stomach Worms (Draschia megastoma & Habronema muscae)

Lifecycle: Stomach worm larvae are ingested by fly maggots in manure. The worms develop inside the maggots. Mature flies then deposit the larvae on the lips, nostrils, wounds and other naturally moist areas of the horse.

How It Gets Into Your Horse: Stomach worm larvae are swallowed as the horse licks the infested area, or they stay in a wound and create oozing, expanding sores.

Dangers If Left Untreated: Stomach worm larvae can expand a wound and prevent healing, causing "summer sores". Larvae deposited in the eyes can cause conjunctivitis. Larvae that are eaten can cause gastritis and tumor-like growths which may rupture.
