After I was about to reach for something more natural than Frontline and Advantix, which not helped by the way this year, we tried Melaflon from Anibio. I do not know whether the ticks are generally become so little, or if it really is in this preparation. The fact is after about 2-3 times application (every 7-10 days a few drops = after about 14 days period of use) we have no problem with the pests.
