I'm glad to know we aren't the only ones fighting the flea battle. Not a flea in sight until about a week ago. Then, wham! And Roxy and Remi both were treated with Advantix K9. So, I soaked them and scrubbed them and picked all the half dead fleas off, I thought. The came back so I tried BioSpot since Roxy has developed an alergy to the Advantix. Fleas gone for 1 day then back they came. Dawn is next since I don't dare put anything else on them for a couple weeks. I think I'll try Frontline Plus. I HATE FLEAS. Mosquitoes and fleas - what was God thinking?
