hard to kill mites from the horse lovers mouth(mom) . have you heard of pig oil its a mixture of mineral oil and yellow sulfur her 1st choice , her second choice is castor oil, but she did say tea tree oil , neem oil and something called dmso also works well . these are topical ointments only and I was instructed to tell you not to exceed 10 percent sulfur in the pig oil mixture . moxidectin or ivermectin orally is recommended , I take moxidectin with no food or drink for at least 1 hour after taking , no reason to use more than the recommended dose of moxidectin . P.S. no baby yet and its 315pm eastern usa time and it might be much later as she only dialated to 3 cm
