I don't have anything on the flea bites while bathing, but I've done quite a bit of research into flea/tick treatments later. I know several people who use Comfortis and like it, and we've had very good luck with Trifexis (flea/tick/worm). We do, however, have these crazy mutated fleas that can pretty much beat any of the topical flea treatment (Advantage, Frontline, etc) and even with the Trifexis we've pulled a very few off Ghost this spring. A lot of the folks on my Husky forum use natural repellants, and I've recently added those into our arsenal. I use a combination of Tea Tree, Lavender, and Rose Geranium oils and haven't seen a flea since we started with them. Aaron is a little sensitive to the rather potent scent of the oils so I'm careful when I apply them, but all you do is a single drop of each on the collar as needed. We're applying weekly here, just because fleas are so horrible in this area. In addition to the three I use, I know people who use Cottonwood oil as part of their treatment. We're going to continue with the Trifexis, but I have several friends who use nothing but the oils and a commercial heartworm medication, and never have fleas. You can get any of the oils on Amazon, and they're really not expensive and last a long time.
