I've been using Frontline for Sasha for 3 years now and have always given it April-September and then skipped the cooler months. She really isn't outside that much. I think next year, I'm going to switch to Advantix because we have more of a problem with mosquitoes than anything around my house and I like the fact that Advantix not only kills everything but also repels against it whereas Frontline doesn't actually repel. |
