Fleas can build up a resistance to flea products so you might want to try another brand. Advantage isn't waterproof so you just wash it off when you bathe him. K9 Advantix or Frontline are both waterproof.
You obviously have an infestation and fleas are hatching in your carpets. I've never had any luck with sprays. Adam carpet powder works the best if you can find it. You have to work the powder in with a broom.
I had a problem last summer with fleas and had to switch from Frontline to K9 Advantix. I still kept seeing tiny little hatchlings until I treated my carpet. That finally did it. |
