I fought these things off and on for years. My dog and some of my friends dogs have also had to fight this off. I was putting Vanguard (with mite control) flea control drops on my dog and thought... why not... and put just a couple of drops on my arm... in 2 days I was itch free and stayed that way for quite a while. They came back, I treated again. I don't have any idea the long term complications of my actions... but that was first back in 2011 and pretty much they were gone until I recently moved and got old bed clothing out of storage and now... we're back to fighting them again! But one thing I do like about using the frontline... every time they bite me I'm poisoning them. After a while it would seem that if they all take a bit, they'll all die.
