 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.
