We missed a worming and discovered worms and wormed with a pour on over a week ago, we are still seeing traces of worms (never saw any alive), should we wait a while or reworm with something else?
If you just dewormed these cattle a week or two ago, then no...this is not an instant fix. Give ur product a chance to work and watch the cattle for any signs of needing deworming again...manure sticking to their hip or tail, not gaining, dull hair coat, etc. If they don't start to change within 30 to 60 days, you might follow up with a different product that also has a different active ingredient.
