The good news is that it's just fleas. The bad news is that the suckers have become immune to pretty much anything. I've never seen as many fleas as I've seen this year. I used to apply a dosage of Frontline or Advantix in May/ June and was good to go for the whole year. Now, they don't give a darn about any of these. I have to use a combination of flea drops from the vet's office, insecticides outside of the house and a chrysanthemum based powder inside of the house, and baths, every month.
