What finally worked for me was using a good tea tree oil shampoo and tea tree oil cream rinse that I leave in. Every couple of months, I feel them trying to start up again though. I'm thinking that boric acid is safe for the eyes, so I can even use boric acid on my eyelashes and eyebrows. The creepy little mites have eaten over half my eyelashes. UGH! and I don't think tea tree oil is safe around the eyes!
