We religiously use the powder and it has been amazing so far! We live in the Midwest (Quad cities, IA) and we have a farm near here. We also live on an acre of land filled with trees, wildlife and ticks. So our pup (5 months old) is constantly exposed to ticks. When I remember to use the flea + tick spray that’s an added bonus. So our dog did have one tick so far, but it was just crawling on his fur. That’s bound to happen regardless. So I have been really happy with this product so far. I use the “tickless” tag as well and that hangs on his collar. But he doesn’t always have a collar on so I wanted a couple lines of defense especially because we are constantly in foresty areas where ticks are very prevalent. I would recommend these products, because I was very skeptical of switching to natural but it works!!
