Do you have to keep horses in after worming?

You don't need to keep your horse stabled after worming them. Worms will be killed by the wormer, so they won't pass into your pasture through droppings.

How long after worming horse are worms expelled?

If your horse has a low worm burden, you may not see any worms being expelled at all. For horses with a large worm burden, they may expel worms for 3 to 4 days after deworming. This is because the dead or paralyzed worms can take a long time to exit via the digestive system.
