Yes but I didn’t see other brands that were cheaper including shipping to me. Everything is cheaper if you can personally get to the store. It does make a big quantity mixed however.That is what I used...seemed to work fine. Was a bit expensive, but when you consider how much it makes diluted properly, I felt it was quite reasonable.
I admit I also did some panic buying, freaking out about the mites, so after some research I got some preventive things with citric acid in them, wet and dry: I bought the Saturday Lime, and I bought bottles of Poultry Shield here and there until I eventually found Walmart has it most reasonably priced (relative term!), so now I have five bottles. But these sound like good preventatives and will keep.
