Here is a tip for those who are ordering ivermectin from Amazon. Many products (targeted toward horses) say 'apple flavor'. This type is a sticky jelly and messy to use topically. However, the Horse Health brand is a white paste. It comes in a big plunger and is 1.87% so you need to cut it about in half with a lotion or cream of your choice. It is quite inexpensive and they ship fast.
