Pigs & Ticks

[Zephyr Farms]

My friend and I got our first piglets a couple of days ago. We've penned them next to the dog pens and they seem to be getting what we think are ticks. They are primarily located on the soft skin parts behind the ears, in the ears, 'armpits, with a few located over their body. We've heard lots of ideas on what to do to kill them but no-one seems to have a concrete answer. We wormed them with Ivomec but that hasn't helped. Suggestions?????
