I have a dreadful time with ticks every year. We've used Frontline plus, but it never works too well for us. We spray the yard and that helps a lot, but we still find a good amount of ticks. We've tried a natural garlic thing and that kind of worked too. We've not found anything that works 100%.

I've not tried K9 Advantex because I always pick up Frontline while I'm at the feed store and they don't have K9 Advantex, I do want to try it though.
