I'll share another good repellent with you. Treat your dog with a good, internal flea and tick repellent, like Frontline. Then, spend a lot of time with your dog, petting him. Insects seem to stay away from you then.
Previously, I would be put into bed for a week by these critters every spring until I had developed a resistence. My lymph nodes would swell up like walnuts.
It's win-win!
Just no heavy petting.
I think there's more to these critters than a simple bite. I worry that they're passing a bacteria, maybe something like Lyme Disease.
