Pig Swig Wormer
Generally you want to deworm most animals twice.....once to get rid of the adults and larva and a second time to get rid of newly hatched eggs. I have read in this forum though that some people don't deworm unless they see worms in the droppings while others say you shouldn't wait for an infestation. The bottle should give you directions. You might also contact the Agricultural specialist for your area. If he doesn't know he can find out for you. So should the person who sold you the stuff btw.
