I feel really dumb asking this, so I'm just going to go ahead and say it.
Is there a reason that I can't just give my horse paste dewormer mixed in with his grain?
I'm normally crazy about going deep into detail about my situation, but there's not really any point now, I just have a horse that absolutely hates to be dewormed.
I can use molasses or applesause if I need to, but since this is obviously easier to do (and he'll eat anything if it's in his grain) and costs no money, I'll do it if it's okay to do, but if it's not I will go to other methods, simple as that. No need to lecture me or anything like that, a yes or no with simple explanation is just fine here.
