I bought some this weekend, too. I went with the water based because I thought it would be better than the alcohol based. Also went with the no IGR. I just frontlined the dogs a week ago, so I can't use the Adams on them yet, but I am going to spray their bedding. Saw my first tick on the dogs in years a week ago. All this dam rain. Looking forward to trying it, and I may get some lavender baby powder too, after reading the other post
