I would personally recommend a conventional wormer to be used, even if you are going to try out DE. Most of what I've read is that it does absolutely nothing for internal parasites (it is fine for mild infection of external parasites). It is likely serendipitous when it does 'work' for internal parasites. A dry, hot climate can help kill parasite oocystes in feces before they can be ingested by another animal, for example, leading to a low parasite load.Ok thank u! Ill have to write all this down before I go to the feed store. Oh and yes I understood about the DE. I've read a lot on it and it seems to be controversial as to whether it works. But no one has said its hurt their animals so I might as well try it! Thank you for your help!![]()
