I use Frontline because it also kills ticks and they are very active in Fl. Check the dosage, is it correct? Because of their fur, I will sometimes see a flea, usually it is dead and "stuck". You could try another kind. But, as a whole, all of this type is effective. The other thought I have is to make sure you wait a couple of days before bathing. I think the rule is two days before and two days after, otherwise, it is ineffective. |
